Overview of Changes from GTK+ 2.90.7 to 2.91.0
==============================================
* The rendering cleanup work has landed. This is a large change that
affects many APIs.
- All gtkstyle functions have been changed to take a cairo_t argument
instead of a window + area.
- GdkPixmap is gone. APIs that took pixmaps are being replaced by ones
that take pixbufs or cairo surfaces, or regions (where pixmaps were
used as masks). In background handling, pixmaps have been replaced
by cairo patterns, see gdk_window_set_background_pattern().
- GdkColormap is gone. It is replaced by visuals, see
gtk_widget_set_visual().
- The ::expose-event signal on GtkWidget has been replaced by a
::draw signal.
- gtk_widget_get_snapshot() has been removed. Instead, gtk_widget_draw()
can render a widget onto an cairo_t.
* The GtkSizeRequest interface has been merged into GtkWidget, and
GtkCellSizeRequest has been merged into GtkCellRenderer. The wrapper
functions have been renamed to include 'preferred', e.g
gtk_size_request_get_width() is now gtk_widget_get_preferred_width()
and gtk_cell_size_request_get_width_for_height() is now
gtk_cell_renderer_get_preferred_width_for_height().
* GtkObject has been removed. The ::destroy signal has been moved
to GtkWidget. At the same time, GtkWidgetFlags have been removed,
they already had getters and setters anyway.
* GtkWidget has gained generic alignment and padding properties:
halign, valign, margin-left, margin-right, margin-top, margin-bottom
These can be used instead of container-specific child properties or
GtkMisc and GtkAlignment widgets.
* Container widgets can now let GTK+ handle border-width for them, using
gtk_container_class_handle_border_width()
* The GtkEditableClass struct has been renamed to GtkEditableInterface
* Mouse wheel scrolling has been removed from GtkNotebook
* The default policy for scrolled windows has been changed to 'automatic'
* Global url hooks have been removed from GtkAboutDialog and GtkLinkButton
* The global window creation hook has been removed from GtkNotebook
* The error handling in GDK has been modernized and avoids synchronizing
X requests as much as possible
* Fixed Bugs:

property, including setter/getter, the GTK_DIALOG_NO_SEPARATOR
flag and the GtkMessageDialog::use-separator style property
- gtk_status_icon_set/get_blinking

- The GtkItem class has been removed. Its functionality has
been merged into is sole subclass, GtkMenuItem
* The GtkIconView::orientation property has been renamed
to 'item-orientation'
* GtkProgressBar and GtkCellRendererProgress implement GtkOrientable
now, and their 'orientation' property have been split into
a 'orientation' property of type GtkOrientation and a boolean
'inverted' property
* GDK no longer exports variables: gdk_threads_lock, gdk_threads_unlock,
gdk_threads_mutex and gdk_display are no longer available
* GTK no longer exports variables: gtk_major_version, gtk_minor_version,
gtk_micro_version, gtk_binary_age, gtk_interface_age have been
converted to functions. gtk_debug_flags has a getter and a setter.
Misc. variables that had been exported by the semi-private text
API have been removed.
* All GDK keysym names have been changed from GDK_keysym to GDK_KEY_keysym;
the previous names are still available in gdkkeysyms-compat.h.
* GtkWrapBox is a new container, which distributes its children
over multiple rows/columns
* GTK+ now uses standard icon names when looking up stock icons
* More widgets and cell renderers have been converted to support
width-for-height: GtkCellRendererText, GtkAccelLabel, GtkCellView,

Overview of Changes from GTK+ 2.90.1 to 2.90.2
==============================================
* GtkApplication: an application class, based on GApplication. Currently,
this is fairly minimal, but it is good enough already to replace libunique.
Future work:
- Add a way to say "This is my application menubar", which gets
put into all toplevel windows on non-OS-X, and into the top
on OS X
- Support session management
- Maybe support application settings
* Misc new api:
- gtk_window_has_group: determines if a window is part of a window group
- gtk_status_bar_remove_all: removes all messages from a statusbar
* DND on offscreen windows works now
* GtkIconView:
- arrow keynav can now be connected over adjacent icon views
* GtkAssistant:
- gtk_assistant_commits: prevents going back beyond a certain
point in the page sequence, adjust shown buttons appropriately
- It is now officially supported to have a progress page at the
end of the page sequence
* Introspection:
- Many annotation fixes
- gdkx.h api is exported in a separate typelib, GdkX11-3.0
* Cleanups:
- the draw_string function has been removed from GtkStyle
- gdk_get/set_use_xshm have been removed
- Deprecated gdk_color api has been removed
* Documentation related to GTK+ 1.2, etc has been removed. Instead
there is an initial GTK+ 3 porting guide now.
* Bugs fixed:
620509 Progress bar rendering is broken
607628 DnD operation doesn't work when using offscreen.
619838 kill off references to gtk 1.2 in docs/comments
608218 GtkOffscreenWindow causes bad window with GtkEntry

Overview of Changes from GTK+ 2.90.0 to 2.90.1
==============================================
* Printing: The list of locales using US Letter papersize has
been updated to match the CLDR 1.8.1
* The default location for the 'module cache' files (ie the files
produced by gdk-pixbuf-query-loaders and gtk-query-immodules) has
been changed to $libdir/gtk-3.0/3.0.0/{loaders,immodules}.cache.
This should avoid multilib problems with the previous location.
Additionally, the query utilities accept an --update-cache argument
to update the cache file directly, instead of writing to stdout
* gtk_radio_action_join_group: A binding-friendly way to manage
radio actions.
* GtkAdjustment enforces values to the range [lower, upper - page_size]
* GDK has been GSEALed, with the addition of suitable accessors
* The XI2 branch with better support for multiple input devices has
been merged, together with backends for XInput, XInput2, win32 and
Quartz, and corresponding updates to input-device handling code
in GTK.
* A number of orientable widgets are no longer abstract: GtkBox,
GtkButtonBox, GtkPaned, GtkRuler, GtkScale, GtkScrollbar, GtkSeparator.
All of these can now be instantiated and flipped between horizontal
and vertical orientation at runtime. Their H/V subclasses are still
available, as convenience API.
* More deprecated API has been removed
* Bugs fixes:
613132 GtkBoxChild should probably be deprecated
592580 GDK needs sealing
618870 GTK+ uses wrong pkg-config to reveal the CAIRO_PREFIX
616817 Remove code to support deprecated GtkToolbar api
619114 undefined reference to `XkbBell'
617863 Actually expose the X11 funcs through introspection
613302 GtkWidget not emitting the unmap signal
565559 Incorrect leave-notify signals for treeview
533946 GtkHScale does not update correctly
618000 Sync paper size fallbacks with CLDR 1.8.1
614581 Gtk print dialog freezes on start up
551322 configure does not use -lm in jasper (JPEG2000) testing

Overview of Changes from GTK+ 2.20.x to 2.90.0
==============================================
* GtkExtendedLayout: Width-for-height geometry management.
This change is known to currently cause minor problems in
some applications, see
617444 GNU emacs warnings with extended layout GTK+
617556 inkscape toolbars broken with extended layout
* GtkExtendedLayout: Width-for-height geometry management
* gtk_icon_theme_load_symbolic: Support for 'symbolic' icons
* Applications can indicate their preference for a dark theme
variant by setting GtkSettings::gtk-application-prefer-dark-theme
* GtkTreeModelFilter can be more usefully subclassed
* Tooltip positioning has been changed to make it less likely
that the tooltip covers up the widget that it relates to
* Deprecated functions have been removed (though some more work
remains to be done in GDK)
* This release is parallel installable with GTK+ <= 2.22, by renaming
.pc files, libraries, include paths, module paths, gtkrc files, etc
to include a '3.0' in its name.
* Updated translations:

to GTK_SENSITIVITY_ON, so that the button is always sensitive or
GTK_SENSITIVITY_OFF to make it insensitive respectively.
* GtkAdjustment now enforces that values are restricted to the
range [lower, upper - page_size]. This has always been the documented
behaviour, and the recommended practice is to set page_size to 0
when using adjustments for simple scalar values, like in a slider
or spin button.
* In the early 2.14.x releases, GtkAdjustment was changed to enforce
that values are restricted to the range [lower, upper - page_size].
This has always been the documented behaviour, and the recommended
practice is to set page_size to 0 when using adjustments for simple
scalar values, like in a slider or spin button.
Due to the large number of applications that are affected by this
change, the behaviour has been reverted to the old behaviour in
2.14.3, with an explicit warning that this change will be
reintroduced in 2.90.
* gdk-pixbuf will use GIO for mime type detection if possible. For
this to work, shared-mime-info needs to be installed and XDG_DATA_DIRS

2000-08-25 John Harper <john@dcs.warwick.ac.uk>
Work to create an Xlib version of gdk-pixbuf (with the Xlib
port of GdkRGB for rendering):
* configure.in: check for X libraries, set and substitute
GDK_PIXBUF_XLIB_{LIBDIR,INCLUDEDIR,LIBS} variables
* gdk_pixbuf_xlibConf.sh.in: new file -- gnome-config details
for the gdk-pixbuf-xlib library
* Makefile.am: build and install gdk_pixbuf_xlibConf.sh
* gdk-pixbuf/gdk-pixbuf-xlib-render.c,
gdk-pixbuf/gdk-pixbuf-xlib.c, gdk-pixbuf/gdk-pixbuf-xlib.h,
gdk-pixbuf/gdk-pixbuf-xlib-private.h,
gdk-pixbuf/gdk-pixbuf-xlib-drawable.c: new files, ported the
GDK dependent parts of gdk-pixbuf to use Xlib. Functions that
were called gdk_pixbuf_FOO are now gdk_pixbuf_xlib_FOO
* gdk-pixbuf/gdk-pixbuf-xlibrgb.c,
gdk-pixbuf/gdk-pixbuf-xlibrgb.h: added Chris Blizzard's Xlib
port of GdkRGB (from Mozilla CVS)
* gdk-pixbuf/Makefile.am: build a library libgdk_pixbuf_xlib.la
including the non-GDK dependent objects from libgdk_pixbuf.la
plus the Xlib ports and xlibrgb

GTK+ Coding Style
-------------------------------------------------------------------------------
This document is intended to be a short description of the preferred
coding style to be used for the GTK+ source code. It was strongly
inspired by Clutter's CODING_STYLE.
Coding style is a matter of consistency, readability and maintainance;
coding style is also completely arbitrary and a matter of taste. This
document will use examples at the very least to provide authoritative
and consistent answers to common questions regarding the coding style,
and will also try to identify the allowed exceptions.
The examples will show the preferred coding style; the negative examples
will be clearly identified. Please, don't submit code to GTK+ that
looks like any of these.
Part of the rationales for these coding style rules are available either
in the kernel CodingStyle document or in Cairo's CODING_STYLE one.
When in doubt, check the surrounding code and try to imitate it.
+ Line width
The maximum line width for source files is 80 characters, whenever possible.
Longer lines are usually an indication that you either need a function
or a pre-processor macro.
+ Indentation
Each new level is indented 2 or more spaces than the previous level:
if (condition)
single_statement ();
This can only be achieved using space characters. It may not be achieved
using tab characters alone, or using a combination of spaces and tabs.
Do not change the editor's configuration to change the meaning of a
tab character (see below); code using tabs to indent will not be accepted
into GTK+.
Even if two spaces for each indentation level allows deeper nesting than
8 spaces, GTK+ favours self-documenting function names that can take
quite some space. For this reason you should avoid deeply nested code.
+ Tab characters
The tab character must always be expanded to spaces. If a literal
tab must be used inside the source, the tab must always be interpreted
according to its traditional meaning:
Advance to the next column which is a multiple of 8.
[ these two lines should be aligned ]
+ Braces
Curly braces should not be used for single statement blocks:
if (condition)
single_statement ();
else
another_single_statement (arg1);
In case of multiple statements, curly braces should be put on another
indentation level:
if (condition)
{
statement_1 ();
statement_2 ();
statement_3 ();
}
The "no block for single statements" rule has only four exceptions:
① if the single statement covers multiple lines, e.g. for functions with
many arguments, and it is followed by else or else if:
/* valid */
if (condition)
{
a_single_statement_with_many_arguments (some_lengthy_argument,
another_lengthy_argument,
and_another_one,
plus_one);
}
else
another_single_statement (arg1, arg2);
② if the condition is composed of many lines:
/* valid */
if (condition1 ||
(condition2 && condition3) ||
condition4 ||
(condition5 && (condition6 || condition7)))
{
a_single_statement ();
}
③ Nested if's, in which case the block should be placed on the
outermost if:
/* valid */
if (condition)
{
if (another_condition)
single_statement ();
else
another_single_statement ();
}
/* invalid */
if (condition)
if (another_condition)
single_statement ();
else if (yet_another_condition)
another_single_statement ();
④ If either side of an if-else statement has braces, both sides
should, to match up indentation:
/* valid */
if (condition)
{
foo ();
bar ();
}
else
{
baz ();
}
/* invalid */
if (condition)
{
foo ();
bar ();
}
else
baz ();
In general, new blocks should be placed on a new indentation level,
like:
int retval = 0;
statement_1 ();
statement_2 ();
{
int var1 = 42;
gboolean res = FALSE;
res = statement_3 (var1);
retval = res ? -1 : 1;
}
While curly braces for function definitions should rest on a new line
they should not add an indentation level:
/* valid */
static void
my_function (int argument)
{
do_my_things ();
}
/* invalid */
static void
my_function (int argument) {
do_my_things ();
}
/* invalid */
static void
my_function (int argument)
{
do_my_things ();
}
Curly braces must not be placed on the same line as a condition:
/* invalid */
if (condition) {
statement_1 ();
statement_2 ();
}
+ Conditions
Do not check boolean values for equality:
/* invalid */
if (condition == TRUE)
do_foo ();
/* valid */
if (another_condition)
do_bar ();
Even if C handles NULL equality like a boolean, be explicit:
/* valid */
if (some_pointer == NULL)
do_blah ();
/* invalid */
if (some_other_pointer)
do_blurp ();
In case of conditions split over multiple lines, the logical operators should
always go at the end of the line:
/* invalid */
if (condition1
|| condition2
|| condition3)
{
do_foo ();
}
/* valid */
if (condition1 &&
condition2 &&
(condition3 || (condition4 && condition5)))
{
do_blah ();
}
+ Functions
Functions should be declared by placing the returned value on a separate
line from the function name:
void
my_function (void)
{
}
The arguments list must be broken into a new line for each argument,
with the argument names right aligned, taking into account pointers:
void
my_function (some_type_t type,
another_type_t *a_pointer,
final_type_t another_type)
{
}
The alignment also holds when invoking a function without breaking the
80 characters limit:
align_function_arguments (first_argument,
second_argument,
third_argument);
To respect the 80 characters limit do not break the function name from
the arguments:
/* invalid */
a_very_long_function_name_with_long_parameters
(argument_the_first, argument_the_second);
/* valid */
first_a = argument_the_first;
second_a = argument_the_second;
a_very_long_function_name_with_long_parameters (first_a, second_a);
+ Whitespace
Always put a space before a parenthesis but never after:
/* valid */
if (condition)
do_my_things ();
/* valid */
switch (condition)
{
}
/* invalid */
if(condition)
do_my_things();
/* invalid */
if ( condition )
do_my_things ( );
A switch() should open a block on a new indentation level, and each case
should start on the same indentation level as the curly braces, with the
case block on a new indentation level:
/* valid */
switch (condition)
{
case FOO:
do_foo ();
break;
case BAR:
do_bar ();
break;
}
/* invalid */
switch (condition) {
case FOO: do_foo (); break;
case BAR: do_bar (); break;
}
/* invalid */
switch (condition)
{
case FOO: do_foo ();
break;
case BAR: do_bar ();
break;
}
/* invalid */
switch (condition)
{
case FOO:
do_foo ();
break;
case BAR:
do_bar ();
break;
}
It is preferable, though not mandatory, to separate the various cases with
a newline:
switch (condition)
{
case FOO:
do_foo ();
break;
case BAR:
do_bar ();
break;
default:
do_default ();
}
The 'break' statement for the default: case is not mandatory.
If a case block needs to declare new variables, the same rules as the
inner blocks (see above) apply; the break statement should be placed
outside of the inner block:
switch (condition)
{
case FOO:
{
int foo;
foo = do_foo ();
}
break;
...
}
When declaring a structure type use newlines to separate logical sections
of the structure:
struct _GtkWrapBoxPrivate
{
GtkOrientation orientation;
GtkWrapAllocationMode mode;
GtkWrapBoxSpreading horizontal_spreading;
GtkWrapBoxSpreading vertical_spreading;
guint16 vertical_spacing;
guint16 horizontal_spacing;
guint16 minimum_line_children;
guint16 natural_line_children;
GList *children;
};
Do not eliminate whitespace and newlines just because something would
fit on 80 characters:
/* invalid */
if (condition) foo (); else bar ();
Do eliminate trailing whitespace on any line, preferably as a separate
patch or commit. Never use empty lines at the beginning or at the end of
a file.
Do enable the default git pre-commit hook that detect trailing
whitespace for you and help you to avoid corrupting GTK+'s tree with
it. Do that as follows:
chmod a+x .git/hooks/pre-commit
You might also find the git-stripspace utility helpful which acts as a
filter to remove trailing whitespace as well as initial, final, and
duplicate blank lines.
+ Headers
Headers are special, for GTK+, in that they don't have to obey the
80 characters limit. The only major rule for headers is that the function
definitions should be vertically aligned in three columns:
return value function_name (type argument,
type argument,
type argument);
The maximum width of each column is given by the longest element in the
column:
void gtk_type_set_property (GtkType *type,
const gchar *value,
GError **error);
G_CONST_RETURN gchar *gtk_type_get_property (GtkType *type);
It is also possible to align the columns to the next tab:
void gtk_type_set_prop (GtkType *type,
gfloat value);
gfloat gtk_type_get_prop (GtkType *type);
gint gtk_type_update_foobar (GtkType *type);
Public headers should never be included directly:
#if !defined (__GTK_H_INSIDE__) && !defined (GTK_COMPILATION)
#error "Only <gtk/gtk.h> can be included directly."
#endif
All headers should have inclusion guards (for internal usage)
and C++ guards:
#ifndef __GTK_FOO_H__
#define __GTK_FOO_H__
#include <gtk/gtk-bar.h>
G_BEGIN_DECLS
...
G_END_DECLS
#endif /* __GTK_FOO_H__ */
+ Includes
GTK+ source files should never include the global gtk.h header, but
instead include the individual headers that are needed. Every file must
include config.h first, then its own header, then other GTK+ headers
that it needs, then system and third-party headers that it needs.
/* valid */
#include "config.h"
#include "gtkfoo.h"
#include "gtkwidget.h"
#include "gtkbutton.h"
...
#include <string.h>
+ GObject
GObject classes definition and implementation require some additional
coding style notices.
Typedef declarations should be placed at the beginning of the file:
typedef struct _GtkFoo GtkFoo;
typedef struct _GtkFooClass GtkFooClass;
typedef struct _GtkFooPrivate GtkFooPrivate;
This includes enumeration types:
typedef enum
{
GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT,
GTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH
} GtkSizeRequestMode;
And callback types:
typedef void (* GtkCallback) (GtkWidget *widget,
gpointer user_data);
Instance structures should only contain the parent type and a pointer to a
private data structure, and they should be annotated as "private":
struct _GtkFoo
{
/*< private >*/
GtkWidget parent_instance;
GtkFooPrivate *priv;
};
All the properties should be stored inside the private data structure, which
is defined inside the source file - or, if needed, inside a private header
file; the private header filename must end with "private.h" and must not be
installed.
The private data structure should only be accessed internally using the
pointer inside the instance structure, and never using the
G_TYPE_INSTANCE_GET_PRIVATE() macro or the g_type_instance_get_private()
function.
Always use the G_DEFINE_TYPE(), G_DEFINE_TYPE_WITH_CODE() macros, or
their abstract variants G_DEFINE_ABSTRACT_TYPE() and
G_DEFINE_ABSTRACT_TYPE_WITH_CODE(), and the similar macros for defining
interfaces.
Interface types should always have the dummy typedef for cast purposes:
typedef struct _GtkFoo GtkFoo;
The interface structure should have "Interface" postfixed to the dummy typedef:
typedef struct _GtkFooInterface GtkFooInterface;
Interfaces must have the following macros:
- Macro: - Expands to:
• GTK_TYPE_<iface_name> <iface_name>_get_type
• GTK_<iface_name> G_TYPE_CHECK_INSTANCE_CAST
• GTK_IS_<iface_name> G_TYPE_CHECK_INSTANCE_TYPE
• GTK_<iface_name>_GET_IFACE G_TYPE_INSTANCE_GET_INTERFACE
+ Memory allocation
When dynamically allocating data on the heap either use g_new() or,
if allocating multiple small data structures, g_slice_new().
Public structure types should always be returned after being zero-ed,
either explicitly for each member, or by using g_new0() or g_slice_new0().
+ Macros
Try to avoid private macros unless strictly necessary. Remember to #undef
them at the end of a block or a series of functions needing them.
Inline functions are usually preferable to private macros.
Public macros should not be used unless they evaluate to a constant.
+ Public API
Avoid exporting variables as public API, since this is cumbersome on some
platforms. It is always preferable to add getters and setters instead.
All public functions must be listed in the gtk.symbols file.
+ Private API
Non-exported functions that are needed in more than one source file
should be named "_gtk_...", and declared in a private header file.
Underscore-prefixed functions are never exported.
Non-exported functions that are only needed in one source file
should be declared static.
+ Documentation
All public APIs must have gtk-doc comments. For functions, these should
be placed in the source file, directly above the function.
/* valid */
/**
* gtk_get_flow:
* @widget: a #GtkWidget
*
* Gets the flow of a widget.
*
* Note that flows may be laminar or turbulent...
*
* Returns: (transfer none): the flow of @widget
*/
GtkFlow *
gtk_get_flow (GtkWidget *widget)
{
...
}
Doc comments for macros, function types, class structs, etc should be
placed next to the definitions, typically in headers.
Section introductions should be placed in the source file they describe,
after the license header:
/* valid */
/**
* SECTION:gtksizerequest
* @Short_Description: Height-for-width geometry management
* @Title: GtkSizeRequest
*
* The GtkSizeRequest interface is GTK+'s height-for-width (and
* width-for-height) geometry management system.
* ...
*/
To properly document a new function, macro, function type or struct,
it needs to be listed in the gtk3-sections.txt file.
To properly document a new class, it needs to be given its own section
in gtk3-sections.txt, needs to be included in gtk-docs.sgml, and the
get_type function needs to listed in gtk3.types.
+ Old code
New code that is being added to GTK+ should adhere to the style
explained above. Existing GTK+ code does largely follow these
conventions, but there are some differences, e.g. occurrences
of tabs, etc.
It is ok to update the style of a code block or function when you
are touching it anyway, but sweeping whitespace changes obscure the
git history and should be avoided.

Some definitions can have a c-declaration field that gives the C code
we parsed to arrive at the definition. The c-declaration is a quoted
string because it can contain parentheses and such.
Defined types and their attributes:
===
(module module-name
(submodule-of module-name)) ;; submodule is optional
Ex: (module Gtk)
Ex: (module Rgb
(submodule-of Gdk))
modules are later referred to with a list of module names, like
(Gdk Rgb) or (Gtk)
Object and boxed type definitions automatically create a submodule.
For example, GtkCList creates the module (module CList (submodule-of
(Gtk))) which is referred to as module (Gtk CList).

"Type" bindings are automatically assumed for objects, boxed types,
etc. as defined below.
The alias field is used to refer to the type later on.
Whenever a type alias can be used, it is also possible to use the
keyword "native", which implies that the type in question is too
C-specific to represent. Then a c-declaration will typically be
available for use.
C types containing [] or () are function pointers or arrays. For
arrays that don't specify a size, we just treat them as pointers. For
function pointers, we need special (type) syntax/attributes of some
kind, but since there basically aren't any of these right now in the
libs we care about we can just ignore them. For arrays that specify a
size ditto, you would handle them by adding an (array-size) attribute
or something or using the "native" keyword and skipping the (type)
stuff.

(parent Object) ;; could say (parent Object (Gtk))

An "object" declaration automatically implies the type definition:

It is never OK to use memcpy() to copy a boxed type, or use
malloc()/free() to alloc/free one.
Ex:
(boxed Pixmap
(in-module (Gdk))
(c-name GdkPixmap)
(ref-func pixmap_ref)
(release-func pixmap_unref))
An "object" declaration automatically implies the type definition:
(type
(alias concat-module-elements-and-boxed-name)
(in-c-name pointer-to-c-name)
(out-c-name pointer-to-pointer-to-c-name)
(inout-c-name pointer-to-c-name))
Ex:
(type (alias GdkPixmap)
(in-c-name GdkPixmap*)
(out-c-name GdkPixmap**)
(inout-c-name GdkPixmap*))
===
(struct struct-name
(in-module modname)
(c-name c-name)
(field (type-and-name type-alias-of-struct-field name-of-struct-field) (access access-rule)))
Unlike a boxed type, a struct type can be copied with memcpy() and
allocated on the stack or with g_malloc().
Ex:
(struct Rectangle
(in-module (Gdk))
(c-name GdkRectangle)
(field (type-and-name gint16 x) (access readwrite))
(field (type-and-name gint16 y) (access readwrite))
(field (type-and-name guint16 width) (access readwrite))
(field (type-and-name guint16 height) (access readwrite)))
Implies GdkRectangle type alias:
(type (alias GdkRectangle)
(in-c-name GdkRectangle*)
(out-c-name GdkRectangle*) ;; note - not the same as boxed types
(inout-c-name GdkRectangle*))
===
(user-function name
(in-module module)
(c-name c-typedef-name)
;; return-type and parameters as for (function)
)
Ex:
(user-function PrintFunc
(in-module (Gtk))
(parameter in (type-and-name gpointer func_data))
(parameter in (type-and-name gchar* str)))
===
(typedef new-name
(in-module module)
(c-name c-full-name)
(orig-type alias-of-orig-type))
Ex:
(typedef Type

CONFIGURING PACKAGES TO WORK WITH GTK
-------------------------------------
Compiling a program successfully against the GTK, GDK, and GLIB
libraries can require a large number of command line options
to your compiler and linker that are hard to guess correctly.
The additional libraries required may, for example, depend on the
manner which GTK was configured
Several tools are included in this package to make process
easier.
First, there is the shell script 'gtk-config' (installed in
$exec_prefix/bin):
Invoking gtk-config
-------------------
gtk-config takes the following flags:
--version
Prints out the version of GTK installed
--cflags
Prints '-I' flags pointing to the installed header files.
--libs
Prints out the linker flags necessary to link a program against GTK
--prefix[=PREFIX]
If PREFIX is specified, overrides the configured value of $prefix.
(And of exec-prefix, unless --exec-prefix is also specified)
Otherwise, prints out the configured value of $prefix
--exec-prefix[=PREFIX]
If PREFIX is specified, overrides the configured value of $exec_prefix.
Otherwise, prints out the configured value of $exec_prefix
You may also add to the command line a list of additional
libraries that gtk-config should supply the CFLAGS and LIBS
for. The only currently supported library is 'gthread'.
As an example of this latter usage, you can get the
appropriate cflags for a threaded program with:
gtk-config --cflags gthread
Example of using gtk-config
---------------------------
Typically, gtk-config will be used within a configure script,
as described below. It, however, can also be used directly
from the command line to compile a simple program. For example:
cc -o simple `gtk-config --cflags` simple.c `gtk-config --libs`
This command line might expand to (for example):
cc -o simple -I/usr/local/lib/glib/include -I/usr/local/include \
-I/usr/X11R6/include simple.c -L/usr/local/lib -L/usr/X11R6/lib \
-lgtk -lgdk -lglib -lXi -lXext -lX11 -lm
Not only is the form using gtk-config easier to type, it will
work on any system, no matter how GTK was configured.
AM_PATH_GTK
-----------
For packages configured using GNU automake, GTK also provides
a macro to automate the process of running GTK.
AM_PATH_GTK([MINIMUM-VERSION, [ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])
This macro:
* Determines the location of GTK using gtk-config, which is either
found in the user's path, or from the environment variable
GTK_CONFIG
* Tests the installed libraries to make sure that there version
is later than MINIMUM-VERSION. (A default version will be used
if not specified)
* If the required version was found, sets the GTK_CFLAGS variable to
the output of `gtk-config --cflags` and the GTK_LIBS variable to
the output of `gtk-config --libs`, and calls AC_SUBST() for these
variables so they can be used in generated makefiles, and then
executes ACTION-IF-FOUND.
* If the required version was not found, sets GTK_CFLAGS and GTK_LIBS
to empty strings, and executes ACTION-IF-NOT-FOUND.
This macro is in file 'gtk.m4' which is installed in $datadir/aclocal.
Note that if automake was installed with a different --prefix than
GTK, you will either have to manually move gtk.m4 to automake's
$datadir/aclocal, or give aclocal the -I option when running it.
Configuring a package that uses AM_PATH_GTK
-------------------------------------------
Simply make sure that gtk-config is in your path, and run
the configure script.
Notes:
* The directory where the GTK libraries are installed needs
to be found by your system's dynamic linker.
This is generally done by
editing /etc/ld.so.conf and running ldconfig
Or by:
setting the environment variable LD_LIBRARY_PATH,
or, as a last resort,
Giving a -R or -rpath flag (depending on your linker) when
running configure, for instance:
LDFLAGS=-R/usr/home/owen/lib ./configure
* You can also specify a gtk-config not in your path by
setting the GTK_CONFIG environment variable to the
name of the executable
* If you move the GTK package from its installed location,
you will need either need to modify gtk-config script
manually to point to the new location or rebuild GTK.
Advanced note:
* configure flags
--with-gtk-prefix=PREFIX
--with-gtk-exec-prefix=PREFIX
are provided to override the prefix and exec-prefix that were stored
in the gtk-config shell script by GTK's configure. You are generally
better off configuring GTK with the right path to begin with.
Example of a package using AM_PATH_GTK
--------------------------------------
The following shows how to build a simple package using automake
and the AM_PATH_GTK macro. The program used here is the testinput.c
You should first read the introductory portions of the automake
Manual, if you are not already familiar with it.
Two files are needed, 'configure.in', which is used to build the
configure script:
==configure.in===
dnl Process this file with autoconf to produce a configure script.
AC_INIT(testinput.c)
AM_INIT_AUTOMAKE(testinput.c, 1.0.0)
AC_PROG_CC
AM_PROG_CC_STDC
AC_PROG_INSTALL
AM_PATH_GTK(0.99.5,
[LIBS="$LIBS $GTK_LIBS"
CFLAGS="$CFLAGS $GTK_CFLAGS"],
AC_MSG_ERROR(Cannot find GTK: Is gtk-config in path?))
AC_OUTPUT(Makefile)
=================
The only command in this which is not standard for automake
is the AM_PATH_GTK() macro.
That command does the following:
If a GTK version greater than 0.99.5 is found, adds $GTK_LIBS to
$LIBS and $GTK_CFLAGS to $CFLAGS. Otherwise, dies with the error
message "Cannot find GTK: Is gtk-config in path?"
And the 'Makefile.am', which will be used to build the Makefile.
== Makefile.am ==
bin_PROGRAMS = testinput
testinput_SOURCES = testinput.c
=================
This Makefile.am, says that we are building a single executable,
from a single sourcefile 'testinput.c'. Since every program
we are building uses GTK we simply added the GTK options
to $LIBS and $CFLAGS, but in other circumstances, we might
want to specify them on a per-program basis: for instance by
adding the lines:
testinput_LDADD = $(GTK_LIBS)
INCLUDES = $(GTK_CFLAGS)
to the Makefile.am.
To try this example out, create a new directory, add the two
files above two it, and copy the testinput.c file from
the gtk/ subdirectory to the new directory. Edit the line:
#include "gtk.h"
in testgtk.c, to read:
#include <gtk/gtk.h>
Now execute the following commands:
automake --add-missing
aclocal
autoconf
You now have a package that can be built in the normal fashion
./configure
make
make install
Notes:
* If you are converting a package that used a pre-1.0 version of
GTK, you should remove the autoconf tests for X. The results
of these tests are included in gtk-config and will be added
to GTK_LIBS and GTK_CFLAGS by the AM_PATH_GTK macro.

<appendix>
<title>Porting applications from &Imlib; to &gdk-pixbuf;</title>
<para>
This appendix contains the basic steps needed to port an
application that uses the &Imlib; library to use &gdk-pixbuf;
instead.
</para>
<note>
<para>
This appendix refers to version 1 of the &Imlib; library; this
discussion is not relevant to Imlib 2. Also, we discuss the
gdk_imlib API instead of the Xlib-based API.
</para>
</note>
<!-- Introduction -->
<sect1>
<title>Introduction</title>
<para>
Prior to the GNOME 1.2 platform, the &Imlib; library was the
preferred way of loading and rendering images in GNOME
applications. Unfortunately, &Imlib; has important design
limitations that make it hard to write efficient and highly
modular applications.
</para>
<para>
The &gdk-pixbuf; library was designed as a solution to
&Imlib;'s shortcomings. It provides a simple, orthogonal API
and convenience functions for the most common operations. In
addition, it supports full transparency information for
images, or alpha channel. More importantly, it has
well-defined semantics for memory management through the use
of reference counting; &Imlib; has an intractably complex
memory management mechanism and cache that will make your head
spin.
</para>
</sect1>
<!-- Differences between Imlib and gdk-pixbuf -->
<sect1>
<title>Differences between &Imlib; and &gdk-pixbuf;</title>
<para>
Generally, applications that use &Imlib; do not have to be
changed extensively to use &gdk-pixbuf;; its simple and
flexible API makes things easy. This section describes the
differences between &Imlib; and &gdk-pixbuf;; you should take
these into account when modifying your applications to use
&gdk-pixbuf;.
</para>
<!-- Initialization -->
<sect2>
<title>Initialization</title>
<para>
The &gdk-pixbuf; library does not need to be initialized.
</para>
<note>
<para>
In GNOME applications you normally don't need to
initialize &Imlib;, as <function>gnome_init()</function>
calls <function>gdk_imlib_init()</function> automatically.
</para>
</note>
</sect2>
<!-- Memory management -->
<sect2>
<title>Memory management</title>
<para>
The &gdk-pixbuf; library provides a simple, well-defined
memory management mechanism for images in the form of
reference counting. This makes it very convenient to use
for large-scale applications that need to share images
between different parts of the program. In stark contrast,
&Imlib; has a terribly complex mechanism of an image and
pixmap cache which makes it very hard for applications to
share image structures between different parts of the
program. Unfortunately this mechanism makes things very
prone to memory leaks and tricky bugs.
</para>
<para>
The basic principle in &gdk-pixbuf; is that when you obtain
a new <link linkend="GdkPixbuf">GdkPixbuf</link> structure,
it is created with an initial reference count of 1. When
another part of the program wants to keep a reference to the
pixbuf, it should call <function>g_object_ref()</function>;
this will increase the reference count by 1. When some part
of the program does not need to keep a reference to a pixbuf
anymore and wants to release the pixbuf, it should call
<function>g_object_unref()</function>; this will decrease
the reference count by 1. When the reference count drops to
zero, the pixbuf gets destroyed or
<emphasis>finalized</emphasis> and its memory is freed.
</para>
<para>
For applications that need to implement a cache of loaded
images, &gdk-pixbuf; provides a way to hook to the last
unreference operation of a pixbuf; instead of finalizing the
pixbuf, the user-installed hook can decide to keep it around
in a cache instead.
</para>
<para>
Finally, &gdk-pixbuf; does not provide a cache of rendered
pixmaps. This is unnecessary for most applications, since
the scaling and rendering functions are quite fast and
applications may need to use subtly different values each
time they call these functions, for example, to take into
account dithering and zooming offsets.
</para>
<para>
Most applications will simply need to call
<function>g_object_ref()</function> when they want to keep
an extra reference to a pixbuf, and then
<function>g_object_unref()</function> when they are done
with it.
</para>
</sect2>
<!-- The Rendering Process -->
<sect2>
<title>The Rendering Process</title>
<para>
The &gdk-pixbuf; library has the policy of always rendering
pixbufs to GDK drawables you provide; it will not create
them for you. This is in general more flexible than
&Imlib;'s policy of always creating a pixmap and making you
use that instead.
</para>
<para>
The disadvantage of always having a pixmap created for you
is that it wastes memory in the X server if you intend to
copy that rendered data onto another drawable, for example,
the final destination window or a temporary pixmap for
drawing. This is the most common case, unfortunately, so
the &Imlib; policy introduces unnecessary copying.
</para>
<para>
Also, &Imlib; can only render pixmaps that are the whole
size of the source image; you cannot render just a subset
region of the image. This is inconvenient for applications
that need to render small portions at a time, such as
applications that do scrolling. Since the whole image must
be rendered at a time, this can lead to performance and
memory usage problems.
</para>
<para>
The &gdk-pixbuf; library lets you render any rectangular
region from an image onto any drawable that you provide.
This lets the application have fine control the way images
are rendered.
</para>

<title>Converting Applications to &gdk-pixbuf;</title>
<para>
This sections describes the actual changes you need to make in
an &Imlib; program to make it use &gdk-pixbuf; instead.
</para>
<!-- Image loading and creation -->
<sect2>
<title>Image loading and creation</title>
<para>
The &gdk-pixbuf; library can load image files synchronously
(i.e. with a single function call), create images from RGB
data in memory, and as a convenience, it can also create
images from inline XPM data.
</para>
<para>
To load an image file in a single function call, simply use
<function>gdk_pixbuf_new_from_file()</function>. Note that
this will make the program block until the whole file has
been read. This function effectively replaces
<function>gdk_imlib_load_image()</function>.
</para>
<para>
If you have RGB data in memory, you can use
<function>gdk_pixbuf_new_from_data()</function> to create a
pixbuf out of it; this is a replacement for
<function>gdk_imlib_create_image_from_data()</function>.
&gdk-pixbuf; does not copy the image data; it is up to you
to define the ownership policy by providing a destroy
notification function that will be called when the image
data needs to be freed. The function you provide can then
free the data or do something else, as appropriate.
</para>
<para>
As a convenience, you can use the
<function>gdk_pixbuf_new_from_xpm_data()</function> function
to create a pixbuf out of inline XPM data that was compiled
into your C program. This is a replacement for
<function>gdk_imlib_create_image_from_xpm_data()</function>.
</para>
<para>
After you have created a pixbuf, you can manipulate it in
any way you please and then finally call
<function>g_object_unref()</function> when you are done
with it. This can be thought of as a replacement for
<function>gdk_imlib_destroy_image()</function> but with much
cleaner semantics.
</para>
</sect2>
<!-- Rendering Images -->
<sect2>
<title>Rendering Images</title>
<para>
Applications that use &Imlib; must first call
<function>gdk_imlib_render()</function> to render the whole
image data onto a pixmap that &Imlib; creates. Then they
must copy that pixmap's data into the final destination for
the image.
</para>
<para>
In contrast, &gdk-pixbuf; provides convenience functions to
render arbitrary rectangular regions of an image onto a
drawable that your application provides. You can use
<function>gdk_draw_pixbuf()</function> to do this; having
your application provide the destination drawable and
specify an arbitrary region means your application has
complete control over the way images are rendered.
</para>
<para>
As a convenience, &gdk-pixbuf; also provides the
<function>gdk_pixbuf_render_pixmap_and_mask()</function>
function; this will create new pixmap and mask drawables for
a whole pixbuf and render the image data onto them. Only
trivially simple applications should find a use for this
function, since usually you want finer control of how things
are rendered.
</para>
</sect2>
<!-- Scaling Images -->
<sect2>
<title>Scaling Images</title>
<para>
&Imlib; lets you render scaled image data at the time you
call <function>gdk_imlib_render()</function>. Again, this
unfortunately scales and renders the whole image onto a new
pixmap.
</para>
<para>
&gdk-pixbuf; provides a number of functions that do scaling
of arbitrary regions of a source pixbuf onto a destination
one. These functions can also perform compositing
operations against the data in the destination pixbuf or
against a solid color or a colored checkerboard.
<footnote>
<para>
You can use a colored checkerboard as the background for
compositing when you want to provide a visual indication
that the image has partially opaque areas. This is
normally used in image editing and viewing programs.
</para>
<para>
Compositing against a single solid color is actually a
special case of a checkerboard; it simply uses checks of
the same color.
</para>
</footnote>
</para>
<para>
Very simple applications may find it sufficient to use
<function>gdk_pixbuf_scale_simple()</function> or
<function>gdk_pixbuf_composite_color_simple()</function>.
These functions scale the whole source image at a time and
create a new pixbuf with the result.
</para>
<para>
More sophisticated applications will need to use
<function>gdk_pixbuf_scale()</function>,
<function>gdk_pixbuf_composite()</function>, or
<function>gdk_pixbuf_composite_color()</function> instead.
These functions let you scale and composite an arbitrary
region of the source pixbuf onto a destination pixbuf that
you provide.
</para>
</sect2>
<!-- Getting Image Data from a Drawable -->
<sect2>
<title>Getting Image Data from a Drawable</title>
<para>
&Imlib; lets you create an image by fetching a drawable's
contents from the X server and converting those into RGB
data. This is done with the
<function>gdk_imlib_create_image_from_drawable()</function>
function.
</para>
<para>
&gdk-pixbuf; provides the
<function>gdk_pixbuf_get_from_drawable()</function> function
instead. It lets you specify a destination pixbuf instead
of always creating a new one for you.
</para>

The &gdk-pixbuf; library provides a simple mechanism to load and represent
animations. An animation is conceptually a series of frames to be displayed
over time. Each frame is the same size. The animation may not be represented
as a series of frames internally; for example, it may be stored as a
sprite and instructions for moving the sprite around a background. To display
an animation you don't need to understand its representation, however; you just
ask &gdk-pixbuf; what should be displayed at a given point in time.

Creating a pixbuf from image data that is already in memory.
<!-- ##### SECTION Long_Description ##### -->
<para>
The most basic way to create a pixbuf is to wrap an existing pixel
buffer with a #GdkPixbuf structure. You can use the
gdk_pixbuf_new_from_data() function to do this You need to specify
the destroy notification function that will be called when the
data buffer needs to be freed; this will happen when a #GdkPixbuf
is finalized by the reference counting functions If you have a
chunk of static data compiled into your application, you can pass
in %NULL as the destroy notification function so that the data
will not be freed.
</para>
<para>
The gdk_pixbuf_new() function can be used as a convenience to
create a pixbuf with an empty buffer. This is equivalent to
allocating a data buffer using <function>malloc()</function> and
then wrapping it with gdk_pixbuf_new_from_data(). The gdk_pixbuf_new()
function will compute an optimal rowstride so that rendering can be
performed with an efficient algorithm.
</para>
<para>
As a special case, you can use the gdk_pixbuf_new_from_xpm_data()
function to create a pixbuf from inline XPM image data.
</para>
<para>
You can also copy an existing pixbuf with the gdk_pixbuf_copy()
function. This is not the same as just doing a g_object_ref()
on the old pixbuf; the copy function will actually duplicate the
pixel data in memory and create a new #GdkPixbuf structure for it.

<!-- ##### SECTION Title ##### -->
GdkPixbufLoader
<!-- ##### SECTION Short_Description ##### -->
Application-driven progressive image loading.
<!-- ##### SECTION Long_Description ##### -->
<para>
#GdkPixbufLoader provides a way for applications to drive the
process of loading an image, by letting them send the image data
directly to the loader instead of having the loader read the data
from a file. Applications can use this functionality instead of
gdk_pixbuf_new_from_file() or gdk_pixbuf_animation_new_from_file()
when they need to parse image data in
small chunks. For example, it should be used when reading an
image from a (potentially) slow network connection, or when
loading an extremely large file.
</para>
<para>
To use #GdkPixbufLoader to load an image, just create a new one,
and call gdk_pixbuf_loader_write() to send the data to it. When
done, gdk_pixbuf_loader_close() should be called to end the stream
and finalize everything. The loader will emit three important
signals throughout the process. The first, "<link
linkend="GdkPixbufLoader-size-prepared">size_prepared</link>",
will be called as soon as the image has enough information to
determine the size of the image to be used. If you want to scale
the image while loading it, you can call gdk_pixbuf_loader_set_size()
in response to this signal.
</para>
<para>The second signal, "<link
linkend="GdkPixbufLoader-area-prepared">area_prepared</link>",
will be called as soon as the pixbuf of the desired has been
allocated. You can obtain it by calling gdk_pixbuf_loader_get_pixbuf().
If you want to use it, simply ref it.
In addition, no actual information will be passed in yet, so the
pixbuf can be safely filled with any temporary graphics (or an
initial color) as needed. You can also call
gdk_pixbuf_loader_get_pixbuf() later and get the same pixbuf.
</para>
<para>
The last signal, "<link
linkend="GdkPixbufLoader-area-updated">area_updated</link>" gets
called every time a region is updated. This way you can update a
partially completed image. Note that you do not know anything
about the completeness of an image from the area updated. For
example, in an interlaced image, you need to make several passes
before the image is done loading.
</para>
<refsect2>
<title>Loading an animation</title>
<para>
Loading an animation is almost as easy as loading an
image. Once the first "<link
linkend="GdkPixbufLoader-area-prepared">area_prepared</link>" signal
has been emitted, you can call gdk_pixbuf_loader_get_animation()
to get the #GdkPixbufAnimation struct and gdk_pixbuf_animation_get_iter()
to get an #GdkPixbufAnimationIter for displaying it.

<para>
This canvas item displays #GdkPixbuf images. It handles full
affine transformations in both GDK and antialiased modes, and also
supports the <ulink url="http://www.w3.org">W3C</ulink>'s <ulink
url="http://www.w3.org/Graphics/SVG/">SVG</ulink>-like scaling and
translation semantics for absolute pixel values.
</para>
<para>
#GdkPixbuf structures may be shared among different pixbuf canvas
items; the pixbuf item uses #GdkPixbuf's reference counting
functions for this.
</para>
<refsect2>
<title>Custom Scaling and Translation</title>
<para>
In addition to the normal affine transformations supported by
canvas items, the #GnomeCanvasPixbuf item supports independent
object arguments for scaling and translation. This is useful
for explicitly setting a size to which the pixbuf's image will
be scaled, and for specifying translation offsets that take
place in the item's local coordinate system.
</para>
<para>
By default, the pixbuf canvas item will attain the size in units
of the #GdkPixbuf it contains. If a #GnomeCanvasPixbuf is
configured to use a #GdkPixbuf that has a size of 300 by 200
pixels, then the pixbuf item will automatically obtain a size of
300 by 200 units in the item's local coordinate system. If the
item is transformed with a scaling transformation of (0.5, 2.0),
then the final image size will be of 150 by 400 pixels.
</para>
<para>
To set custom width and height values, you must set the <link
linkend="GnomeCanvasPixbuf--width-set">width_set</link> or <link
linkend="GnomeCanvasPixbuf--height-set">height_set</link>
arguments to %TRUE, and then set the <link
linkend="GnomeCanvasPixbuf--width">width</link> or <link
linkend="GnomeCanvasPixbuf--height">height</link> arguments to
the desired values. The former two arguments control whether
the latter two are used when computing the final image's size;
they are both %FALSE by default so that the pixbuf item will
attain a size in units equal to the size in pixels of the
#GdkPixbuf that the item contains.
</para>
<para>
The custom translation offsets are controlled by the <link
linkend="GnomeCanvasPixbuf--x">x</link> and <link
linkend="GnomeCanvasPixbuf--y">y</link> arguments. The logical
upper-left vertex of the image will be translated by the
specified distance, aligned with the item's local coordinate
system.
</para>
</refsect2>
<refsect2>
<title>Absolute Pixel Scaling and Translation</title>
<para>
The <ulink url="http://www.w3.org/Graphics/SVG/">Scalable Vector
Graphics</ulink> specification (SVG) of the <ulink
url="http://www.w3.org">World Wide Web Consortium</ulink> also
allows images to be translated and scaled by absolute pixel
values that are independent of an item's normal affine
transformation.
</para>
<para>
Normally, the pixbuf item's translation and scaling arguments
are interpreted in units, so they will be modified by the item's
affine transformation. The <link
linkend="GnomeCanvasPixbuf--width-in-pixels">width_in_pixels</link>,
<link
linkend="GnomeCanvasPixbuf--height-in-pixels">height_in_pixels</link>,
<link
linkend="GnomeCanvasPixbuf--x-in-pixels">x_in_pixels</link>, and
<link
linkend="GnomeCanvasPixbuf--y-in-pixels">y_in_pixels</link>
object arguments can be used to modify this behavior. If one of
these arguments is %TRUE, then the corresponding scaling or
translation value will not be affected lengthwise by the pixbuf
item's affine transformation.
</para>
<para>
For example, consider a pixbuf item whose size is (300, 200).
If the item is modified with a scaling transformation of (0.5,
2.0) but the <link
linkend="GnomeCanvasPixbuf--width-in-pixels">width_in_pixels</link>
is set to %TRUE, then the item will appear to be (300, 400)
pixels in size. This means that in this case the item's affine
transformation only applies to the height value, while the width
value is kept in absolute pixels.
</para>
<para>
Likewise, consider a pixbuf item whose (<link
linkend="GnomeCanvasPixbuf--x">x</link>, <link
linkend="GnomeCanvasPixbuf--y">y</link>) arguments are set to
(30, 40). If the item is then modified by the same scaling
transformation of (0.5, 2.0) but the <link
linkend="GnomeCanvasPixbuf--y-in-pixels">y_in_pixels</link>
argument is set to %TRUE, then the image's upper-left corner
will appear to be at position (15, 40). In this case, the
affine transformation is applied only to the x offset, while the
y offset is kept in absolute pixels.
</para>
<para>
In short, these arguments control whether a particular dimension
of a pixbuf item is scaled or not in the normal way by the
item's affine transformation.
</para>

<para>
When you set the #GdkPixbuf structure that a #GnomeCanvasPixbuf
item will use by setting the <link
linkend="GnomeCanvasPixbuf--pixbuf">pixbuf</link> argument, a
reference count will be added to that #GdkPixbuf structure.
When the pixbuf item no longer needs the #GdkPixbuf structure,
such as when the item is destroyed or when a new pixbuf
structure is passed to it, then the old #GdkPixbuf structure
will be automatically unreferenced.
</para>
<para>
This means that if an application just needs to load a pixbuf
image and set it into a pixbuf canvas item, it can do the
following to &lsquo;forget&rsquo; about the pixbuf structure:
<programlisting>
GdkPixbuf *pixbuf;
GnomeCanvasItem *item;
pixbuf = gdk_pixbuf_new_from_file ("foo.png");
g_assert (pixbuf != NULL);
item = gnome_canvas_item_new (gnome_canvas_root (my_canvas),
gnome_canvas_pixbuf_get_type (),
"pixbuf", pixbuf,
NULL);
gdk_pixbuf_unref (pixbuf);
</programlisting>
</para>
<para>
After this happens, the reference count of the pixbuf structure
will be 1: the gdk_pixbuf_new_from_file() function creates it
with a reference count of 1, then setting the <link
linkend="GnomeCanvasPixbuf--pixbuf">pixbuf</link> argument of
the #GnomeCanvasPixbuf item increases it to 2, and then it is
decremented to 1 by the call to gdk_pixbuf_unref(). When the
canvas item is destroyed, it will automatically unreference the
pixbuf structure again, causing its reference count to drop to
zero and thus be freed.

<para>
The &gdk-pixbuf; library provides several convenience functions to
render pixbufs to GDK drawables. It uses the GdkRGB to render the
image data.
</para>
<para>
At this point there is not a standard alpha channel extension for
the X Window System, so it is not possible to use full opacity
information when painting images to arbitrary drawables. The
&gdk-pixbuf; convenience functions will threshold the opacity
information to create a bi-level clipping mask (black and white),
and use that to draw the image onto a drawable.
</para>
<important>
<para>
Since these functions use GdkRGB for rendering, you must
initialize GdkRGB before using any of them. You can do this by
calling gdk_rgb_init() near the beginning of your program.

<para>
A function of this type can be used to override the default
operation when a pixbuf loses its last reference, i.e. when
gdk_pixbuf_unref() is called on a #GdkPixbuf structure that has a
reference count of 1. This function should determine whether to
finalize the pixbuf by calling gdk_pixbuf_finalize(), or whether
to just resume normal execution. The last unref handler for a
#GdkPixbuf can be set using the
gdk_pixbuf_set_last_unref_handler() function. By default, pixbufs
will be finalized automatically if no last unref handler has been
defined.
</para>
@pixbuf: The pixbuf that is losing its last reference.

<!-- ##### ARG GnomeCanvasPixbuf:height ##### -->
<para>
Indicates the height the pixbuf will be scaled to. This argument
will only be used if the <link

is %TRUE. Works in the same way as the <link
linkend="GnomeCanvasPixbuf--width">width</link> argument.
</para>
<!-- ##### ARG GnomeCanvasPixbuf:height-in-pixels ##### -->
<para>
Works in the same way as the <link
linkend="GnomeCanvasPixbuf--width-in-pixels">width_in_pixels</link>

</para>
<!-- ##### ARG GnomeCanvasPixbuf:height-pixels ##### -->

same way as the <link
linkend="GnomeCanvasPixbuf--width-set">width_set</link> argument.
The default is %FALSE.
</para>
<!-- ##### ARG GnomeCanvasPixbuf:pixbuf ##### -->
<para>
Contains a pointer to a #GdkPixbuf structure that will be used by
the pixbuf canvas item as an image source. When a pixbuf is set
its reference count is incremented; if the pixbuf item kept a
pointer to another #GdkPixbuf structure, the reference count of
this structure will be decremented. Also, the GdkPixbuf's
reference count will automatically be decremented when the
#GnomeCanvasPixbuf item is destroyed. When a pixbuf is queried, a
reference count will not be added to the return value; you must do
this yourself if you intend to keep the pixbuf structure around.
</para>
<!-- ##### ARG GnomeCanvasPixbuf:width ##### -->
<para>
Indicates the width the pixbuf will be scaled to. This argument
will only be used if the <link
linkend="GnomeCanvasPixbuf--width-set">width_set</link> argument
is %TRUE. If the <link
linkend="GnomeCanvasPixbuf--width-in-pixels">width_in_pixels</link>
argument is %FALSE, the width will be taken to be in canvas units,
and thus will be scaled along with the canvas item's affine
transformation. If width_in_pixels is %TRUE, the width will be
taken to be in pixels, and will visually remain a constant size
even if the item's affine transformation changes.
</para>
<!-- ##### ARG GnomeCanvasPixbuf:width-in-pixels ##### -->
<para>
If this argument is %TRUE, then the width of the pixbuf will be
considered to be in pixels, that is, it will not be visually
scaled even if the item's affine transformation changes. If this
is %FALSE, then the width of the pixbuf will be considered to be
in canvas units, and so will be scaled normally by affine
transformations. The default is %FALSE.
</para>
<!-- ##### ARG GnomeCanvasPixbuf:width-pixels ##### -->
<para>
</para>
<!-- ##### ARG GnomeCanvasPixbuf:width-set ##### -->
<para>
Determines whether the <link

%FALSE, then the width value of the pixbuf will be used instead.
This argument is %FALSE by default.
</para>
<!-- ##### ARG GnomeCanvasPixbuf:x ##### -->
<para>
Indicates the horizontal translation offset of the pixbuf item's
image. This offset may not actually appear horizontal, since it
will be affected by the item's affine transformation. The default
is 0.0.
</para>
<!-- ##### ARG GnomeCanvasPixbuf:x-in-pixels ##### -->
<para>
If this argument is %TRUE, the pixbuf's translation with respect
to its logical origin in item-relative coordinates will be in
pixels, that is, the visible offset will not change even if the
item's affine transformation changes. If it is %FALSE, the
pixbuf's translation will be taken to be in canvas units, and thus
will change along with the item's affine transformation. The
default is %FALSE.
</para>
<!-- ##### ARG GnomeCanvasPixbuf:x-pixels ##### -->
<para>
</para>
<!-- ##### ARG GnomeCanvasPixbuf:x-set ##### -->
<para>

coordinates.
</para>
<!-- ##### ARG GnomeCanvasPixbuf:y ##### -->
<para>
Indicates the vertical translation offset of the pixbuf item's
image. Works in the same way as the <link
linkend="GnomeCanvasPixbuf--x">x</link> argument. The default is
0.0.
</para>
<!-- ##### ARG GnomeCanvasPixbuf:y-in-pixels ##### -->
<para>
Works in the same way as the <link
linkend="GnomeCanvasPixbuf--x-in-pixels">x_in_pixels</link>

<title>Image Data</title>
<para>
Image data in a pixbuf is stored in memory in uncompressed,
packed format. Rows in the image are stored top to bottom, and
in each row pixels are stored from left to right. There may be
padding at the end of a row. The "rowstride" value of a pixbuf,

<para>
The following code illustrates a simple put_pixel(<!-- -->)
function for RGB pixbufs with 8 bits per channel with an alpha
channel. It is not included in the gdk-pixbuf library for
performance reasons; rather than making several function calls
for each pixel, your own code can take shortcuts.

This function will not work for pixbufs with images that are
other than 8 bits per sample or channel, but it will work for
most of the pixbufs that GTK+ uses.
</para>
</example>
<note>
<para>
If you are doing memcpy() of raw pixbuf data, note that the
last row in the pixbuf may not be as wide as the full
rowstride, but rather just as wide as the pixel data needs to
be. That is, it is unsafe to do <literal>memcpy (dest,
pixels, rowstride * height)</literal> to copy a whole pixbuf.
Use gdk_pixbuf_copy() instead, or compute the width in bytes
of the last row as <literal>width * ((n_channels *
bits_per_sample + 7) / 8)</literal>.

Module Interface
<!-- ##### SECTION Short_Description ##### -->
Extending &gdk-pixbuf;
<!-- ##### SECTION Long_Description ##### -->
<para>
If &gdk-pixbuf; has been compiled with GModule support, it can be extended by
modules which can load (and perhaps also save) new image and animation
formats. Each loadable module must export a
#GdkPixbufModuleFillInfoFunc function named <function>fill_info</function> and
a #GdkPixbufModuleFillVtableFunc function named
<function>fill_vtable</function>.
</para>
<para>
In order to make format-checking work before actually loading the modules
(which may require dlopening image libraries), modules export their
signatures (and other information) via the <function>fill_info</function>
function. An external utility, <command>gdk-pixbuf-query-loaders</command>,
uses this to create a text file containing a list of all available loaders and
their signatures. This file is then read at runtime by &gdk-pixbuf; to obtain
the list of available loaders and their signatures.
</para>
<para>
Modules may only implement a subset of the functionality available via
#GdkPixbufModule. If a particular functionality is not implemented, the
<function>fill_vtable</function> function will simply not set the corresponding
function pointers of the #GdkPixbufModule structure. If a module supports
incremental loading (i.e. provides #begin_load, #stop_load and
#load_increment), it doesn't have to implement #load, since &gdk-pixbuf; can
supply a generic #load implementation wrapping the incremental loading.
</para>
<para>
Installing a module is a two-step process:
<itemizedlist>
<listitem><para>copy the module file(s) to the loader directory (normally
<filename><replaceable>libdir</replaceable>/gtk-2.0/<replaceable>version</replaceable>/loaders</filename>,

</para></listitem>

<!-- ##### STRUCT GdkPixbufModulePattern ##### -->
<para>
The signature of a module is a set of prefixes. Prefixes are encoded as
pairs of ordinary strings, where the second string, called the mask, if
not %NULL, must be of the same length as the first one and may contain
' ', '!', 'x', 'z', and 'n' to indicate bytes that must be matched,
not matched, "don't-care"-bytes, zeros and non-zeros.
Each prefix has an associated integer that describes the relevance of
the prefix, with 0 meaning a mismatch and 100 a "perfect match".
</para>
<para>
Starting with &gdk-pixbuf; 2.8, the first byte of the mask may be '*',
indicating an unanchored pattern that matches not only at the beginning,
but also in the middle. Versions prior to 2.8 will interpret the '*'
like an 'x'.
</para>

The signature of a module is stored as an array of
#GdkPixbufModulePattern<!-- -->s. The array is terminated by a pattern
where the @prefix is %NULL.

</para>
<para>
The function is expected to set @width and @height to the desired
size to which the image should be scaled. If a module has no efficient
way to achieve the desired scaling during the loading of the image, it may
either ignore the size request, or only approximate it -- &gdk-pixbuf; will
then perform the required scaling on the completely loaded image.
</para>
<para>
If the function sets @width or @height to zero, the module should interpret
this as a hint that it will be closed soon and shouldn't allocate further
resources. This convention is used to implement gdk_pixbuf_get_file_info()
efficiently.

#GdkPixbuf structures are reference counted. This means that an
application can share a single pixbuf among many parts of the
code. When a piece of the program needs to keep a pointer to a
pixbuf, it should add a reference to it by calling g_object_ref().
When it no longer needs the pixbuf, it should subtract a reference
by calling g_object_unref(). The pixbuf will be destroyed when
its reference count drops to zero. Newly-created #GdkPixbuf
structures start with a reference count of one.
</para>

As #GdkPixbuf is derived from #GObject now, gdk_pixbuf_ref() and

you do not need to worry about those. The only function that lets
you specify how to free the pixel data is
gdk_pixbuf_new_from_data(). Since you pass it a pre-allocated

is done with a function of type #GdkPixbufDestroyNotify. When a

destroy notification function will be called, and it is its

Scaling pixbufs and scaling and compositing pixbufs
<!-- ##### SECTION Long_Description ##### -->
<para>
The &gdk-pixbuf; contains functions to scale pixbufs, to scale
pixbufs and composite against an existing image, and to scale
pixbufs and composite against a solid color or checkerboard.
Compositing a checkerboard is a common way to show an image with
an alpha channel in image-viewing and editing software.
</para>
<para>
Since the full-featured functions (gdk_pixbuf_scale(),
gdk_pixbuf_composite(), and gdk_pixbuf_composite_color()) are
rather complex to use and have many arguments, two simple
convenience functions are provided, gdk_pixbuf_scale_simple() and
gdk_pixbuf_composite_color_simple() which create a new pixbuf of a
given size, scale an original image to fit, and then return the
new pixbuf.
</para>
<para>
Scaling and compositing functions take advantage of MMX hardware
acceleration on systems where MMX is supported. If gdk-pixbuf is built
with the Sun mediaLib library, these functions are instead accelerated
using mediaLib, which provides hardware acceleration on Intel, AMD,
and Sparc chipsets. If desired, mediaLib support can be turned off by
setting the GDK_DISABLE_MEDIALIB environment variable.
</para>
<para>
The following example demonstrates handling an expose event by
rendering the appropriate area of a source image (which is scaled
to fit the widget) onto the widget's window. The source image is
rendered against a checkerboard, which provides a visual
representation of the alpha channel if the image has one. If the
image doesn't have an alpha channel, calling
gdk_pixbuf_composite_color() function has exactly the same effect
as calling gdk_pixbuf_scale().

<para>
This enumeration describes the different interpolation modes that
can be used with the scaling functions. @GDK_INTERP_NEAREST is
the fastest scaling method, but has horrible quality when
scaling down. @GDK_INTERP_BILINEAR is the best choice if you
aren't sure what to choose, it has a good speed/quality balance.
<note>
<para>
Cubic filtering is missing from the list; hyperbolic
interpolation is just as fast and results in higher quality.
</para>
</note>
</para>
@GDK_INTERP_NEAREST: Nearest neighbor sampling; this is the fastest
and lowest quality mode. Quality is normally unacceptable when scaling
down, but may be OK when scaling up.
@GDK_INTERP_TILES: This is an accurate simulation of the PostScript
image operator without any interpolation enabled. Each pixel is
rendered as a tiny parallelogram of solid color, the edges of which
are implemented with antialiasing. It resembles nearest neighbor for
enlargement, and bilinear for reduction.
@GDK_INTERP_BILINEAR: Best quality/speed balance; use this mode by
default. Bilinear interpolation. For enlargement, it is
equivalent to point-sampling the ideal bilinear-interpolated image.
For reduction, it is equivalent to laying down small tiles and
integrating over the coverage area.
@GDK_INTERP_HYPER: This is the slowest and highest quality
reconstruction function. It is derived from the hyperbolic filters in
Wolberg's "Digital Image Warping", and is formally defined as the
hyperbolic-filter sampling the ideal hyperbolic-filter interpolated
image (the filter is designed to be idempotent for 1:1 pixel mapping).
