5cededa0aa Improved icon view keynav
Use ::keynav-failed for arrow navigation in icon views, so that
it is possible to override error handling. Also add API to get the
row/col of an item. With this, it is possible to make arrow keynav
span adjacent icon views, which is desired in the new control-center
shell. testiconview-keynav demonstrates this.

cb8c076321 Bug 607628 - DnD operation doesn't work when using offscreen
Changed the way to find the drop widget from a top->bottom recursion
using GdkWindow positions to a liner bottom->top walk up the widget
hierarchy using _gtk_widget_find_at_coords() and
gtk_widget_translate_coordinates(), which both do the right things for
offscreen widgets.

c4b1bbf3e2 Bug 607628 - DnD operation doesn't work when using offscreen
Turn find_widget_under_pointer() into internal API
_gtk_widget_find_at_coords() which is needed for fixing above
bug. This should actually be a public utility function, and will be
moved to another file when its final API has been decided.

6c7dc26935 Revert "Implement GdkRegion in terms of cairo_region_t"
This reverts commit 5616bdc3dc.

I always thought cairo_region_t was a Cairo 1.8 feature. Apparently it
isn't, so the 3 patches I just reverted made Gtk depend on an unreleased
Cairo version. This is obviously not a good thing.

Expect those patches to reland once there's a Cairo 1.10 out (probably
around Gtk 4...)

821dd33918 Deprecate the GdkRegion API
Includes fixing all callers to use the cairo region API instead. This is
usually just replacing the function names, the only difference is
gdk_region_get_rectangles() being replaced by
cairo_region_num_rectangles() and cairo_region_get_rectangle() which
required a bit more work.

43091232a2 Get rid of navigation region in GtkMenu
This completes the move to get rid of using a GdkRegion for the
navigation region and the only user of gdk_region_polygon(). We keep
track of the triangle and compute in/out points ourselves now.

Unfortunately the DRAW_STAYUP_TRIANGLES debugging code doesn't work
using cairo, so I removed it completely.

fc35cd9bfe Added api to reset the im context in GtkTextView and GtkEntry
Also, added api to allow an input method to internally handle
key press and release events in the GtkTextView and GtkEntry
cases.
This is simply a wrapper to the gtk_im_context_filter_keypress()
function, but It's added to not access the ->im_context
directly.

501098e946 Remove the definition of libpixbufloader_gdip_png_la_*
libstatic-pixbufloader-gdip-png.la should not be built or at least not
included in STATIC_GDIPLUS_LIBS as we don't want to use the GDI+-based
loader for PNG, because if we do, we can't get (or was it set?) the
options of a PNG pixbuf that for instance some code in GIMP wants to do.

bd873014ca filechooser: Fix a crash when removing files
The file removal code was not properly clearing the file=>array index
cache, so later lookups into that cache would return invalid array
indexes.

The easiest way to reproduce it is to create a directory with two files
and deleting both of them.

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

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

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
* 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.
619114 undefined reference to `XkbBell'
618093 typo in gtkprintoperation.c, "selecion" should be "selection"
* Updated translations:
Italian
Overview of Changes from GTK+ 2.20.0 to 2.21.0
==============================================
* Support tracker 0.8 and 0.9 in the filechooser search code

- add gdk_window_get_effective_parent() and
gdk_window_get_effective_toplevel() which are offscreen aware
- add gtk_widget_send_focus_change
- add accessors for GtkTextView adjustments
- add API to reset the im context in GtkTextView and GtkEntry
* Bug fixes:
614513 Func to substitute GTK_WIDGET_SET_FLAGS (widget, GTK_HAS_GRAB)?
614510 Needed func for GTK_WIDGET_SET_FLAGS (widget, TOPLEVEL) ?
614515 Func to substitute GTK_WIDGET_SET_FLAGS (widget, GTK_HAS_DEFAULT)?

* 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.

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,

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

<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>
</sect2>
</sect1>
<!-- Converting Applications to gdk-pixbuf -->
<sect1>
<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.

The &gdk-pixbuf; library provides a simple mechanism to load and represent

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>
</refsect2>
<refsect2>
<title>Resource Management</title>
<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,

</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.

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
linkend="GnomeCanvasPixbuf--width">width</link> argument is taken

%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>
Determines whether the <link

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

most of the pixbufs that GTK+ uses.
</para>

<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>

</para></listitem>

The &gdk-pixbuf; interfaces needed for implementing modules are contained in

<!-- ##### 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>
<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>
<note>

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
responsibility to free the pixel array.

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).

These functions provide a low level interface for drag and drop.
The X backend of GDK supports both the Xdnd and Motif drag and drop protocols
transparently, the Win32 backend supports the WM_DROPFILES protocol.

GTK+ provides a higher level abstraction based on top of these functions,
and so they are not normally needed in GTK+ applications.

The #GdkFont data type represents a font for drawing on
the screen. These functions provide support for
loading fonts, and also for determining the dimensions
of characters and strings when drawn with a particular
font.
</para>
<para>
Fonts in X are specified by a
<firstterm>X Logical Font Description</firstterm>.
The following description is considerably simplified.
For definitive information about XLFD's see the
X reference documentation. A X Logical Font Description (XLFD)
consists of a sequence of fields separated (and surrounded by) '-'
characters. For example, Adobe Helvetica Bold 12 pt, has the
full description:
<informalexample><programlisting>
"-adobe-helvetica-bold-r-normal--12-120-75-75-p-70-iso8859-1"
</programlisting></informalexample>
</para>
<para>
The fields in the XLFD are:

</para>
<para>
When specifying a font via a X logical Font Description,
'*' can be used as a wildcard to match any portion of
the XLFD. For instance, the above example could
also be specified as
<informalexample><programlisting>
"-*-helvetica-bold-r-normal--*-120-*-*-*-*-iso8859-1"
</programlisting></informalexample>
It is generally a good idea to use wildcards for any
portion of the XLFD that your program does not care
about specifically, since that will improve the
chances of finding a matching font.
</para>
<para>
A <firstterm>fontset</firstterm> is a list of fonts
that is used for drawing international text that may
contain characters from a number of different character
sets. It is represented by a list of XLFD's.
</para>
<para>
The font for a given character set is determined by going
through the list of XLFD's in order. For each one, if
the registry and and encoding fields match the desired
character set, then that font is used, otherwise if
the XLFD contains wild-cards for the registry and encoding
fields, the registry and encoding for the desired character
set are substituted in and a lookup is done. If a match is found
that font is used. Otherwise, processing continues
on to the next font in the list.
</para>
<para>
The functions for determining the metrics of a string
come in several varieties that can take a number
of forms of string input:
<variablelist>
<varlistentry>
<term>8-bit string</term>
<listitem><para>
When using functions like gdk_string_width() that
take a <type>gchar *</type>, if the font is of type
%GDK_FONT_FONT and is an 8-bit font, then each
<type>gchar</type> indexes the glyphs in the font directly.
</para></listitem>
</varlistentry>
<varlistentry>
<term>16-bit string</term>
<listitem><para>
For functions taking a <type>gchar *</type>, if the
font is of type %GDK_FONT_FONT, and is a 16-bit
font, then the <type>gchar *</type> argument is
interpreted as a <type>guint16 *</type> cast to
a <type>gchar *</type> and each <type>guint16</type>
indexes the glyphs in the font directly.
</para></listitem>
</varlistentry>
<varlistentry>
<term>Multibyte string</term>
<listitem><para>
For functions taking a <type>gchar *</type>, if the
font is of type %GDK_FONT_FONTSET, then the input
string is interpreted as a <firstterm>multibyte</firstterm>
encoded according to the current locale. (A multibyte
string is one in which each character may consist
of one or more bytes, with different lengths for different
characters in the string). They can be converted to and
from wide character strings (see below) using
gdk_wcstombs() and gdk_mbstowcs().) The string will
be rendered using one or more different fonts from
the fontset.
</para></listitem>
</varlistentry>
<varlistentry>
<term>Wide character string</term>
<listitem><para>
For a number of the text-measuring functions, GDK
provides a variant (such as gdk_text_width_wc()) which
takes a <type>GdkWChar *</type> instead of a
<type>gchar *</type>. The input is then taken to
be a wide character string in the encoding of the
current locale. (A wide character string is a string
in which each character consists of several bytes,
and the width of each character in the string is
constant.)

<para>
Specifies a wide character type, used to represent character codes.
This is needed since some native languages have character sets which have
more than 256 characters (Japanese and Chinese, for example).
</para>
<para>
Wide character values between 0 and 127 are always identical in meaning to
the ASCII character codes. The wide character value 0 is often used to
terminate strings of wide characters in a similar way to normal strings
using the char type.
</para>
<para>
An alternative to wide characters is multi-byte characters, which extend
normal char strings to cope with larger character sets. As the name suggests,
multi-byte characters use a different number of bytes to store different
character codes. For example codes 0-127 (i.e. the ASCII codes) often
use just one byte of memory, while other codes may use 2, 3 or even 4 bytes.
Multi-byte characters have the advantage that they can often be used in an
application with little change, since strings are still represented as arrays
of char values. However multi-byte strings are much easier to manipulate since
the character are all of the same size.
</para>
<para>
Applications typically use wide characters to represent character codes
internally, and multi-byte strings when saving the characters to a file.
The gdk_wcstombs() and gdk_mbstowcs() functions can be used to convert from
one representation to the other.
</para>
<para>
See the 'Extended Characters' section of the GNU C Library Reference Manual
for more detailed information on wide and multi-byte characters.

<!-- ##### SECTION Title ##### -->
Input Devices
<!-- ##### SECTION Short_Description ##### -->
Functions for handling extended input devices
<!-- ##### SECTION Long_Description ##### -->
<para>
In addition to the normal keyboard and mouse input devices, GTK+ also
contains support for <firstterm>extended input devices</firstterm>. In
particular, this support is targeted at graphics tablets. Graphics
tablets typically return sub-pixel positioning information and possibly
information about the pressure and tilt of the stylus. Under
X, the support for extended devices is done through the
<firstterm>XInput</firstterm> extension.
</para>
<para>
Because handling extended input devices may involve considerable
overhead, they need to be turned on for each #GdkWindow
individually using gdk_input_set_extension_events().
(Or, more typically, for GtkWidgets, using gtk_widget_set_extension_events()).
As an additional complication, depending on the support from
the windowing system, its possible that a normal mouse
cursor will not be displayed for a particular extension
device. If an application does not want to deal with displaying
a cursor itself, it can ask only to get extension events
from devices that will display a cursor, by passing the
%GDK_EXTENSION_EVENTS_CURSOR value to
gdk_input_set_extension_events(). Otherwise, the application
must retrieve the device information using gdk_devices_list(),
check the <structfield>has_cursor</structfield> field, and,
if it is %FALSE, draw a cursor itself when it receives
motion events.
</para>
<para>
Each pointing device is assigned a unique integer ID; events from a
particular device can be identified by the
<structfield>deviceid</structfield> field in the event structure. The
events generated by pointer devices have also been extended to contain
<structfield>pressure</structfield>, <structfield>xtilt</structfield>
and <structfield>ytilt</structfield> fields which contain the extended
information reported as additional <firstterm>valuators</firstterm>
from the device. The <structfield>pressure</structfield> field is a
a double value ranging from 0.0 to 1.0, while the tilt fields are
double values ranging from -1.0 to 1.0. (With -1.0 representing the
maximum tilt to the left or up, and 1.0 representing the maximum
tilt to the right or down.)
</para>
<para>
One additional field in each event is the
<structfield>source</structfield> field, which contains an
enumeration value describing the type of device; this currently
can be one of %GDK_SOURCE_MOUSE, %GDK_SOURCE_PEN, %GDK_SOURCE_ERASER,
or %GDK_SOURCE_CURSOR. This field is present to allow simple
applications to (for instance) delete when they detect eraser
devices without having to keep track of complicated per-device
settings.
</para>
<para>
Various aspects of each device may be configured.
The configuration of devices is queried using gdk_devices_list().
Each device must be activated using gdk_device_set_mode(), which
also controls whether the device's range is mapped to the
entire screen or to a single window. The mapping of the valuators of
the device onto the predefined valuator types is set using
gdk_device_set_axis_use(). And the source type for each device
can be set with gdk_device_set_source().
</para>
<para>
Devices may also have associated <firstterm>keys</firstterm>
or macro buttons. Such keys can be globally set to map
into normal X keyboard events. The mapping is set using
gdk_device_set_key().
</para>
<para>
The interfaces in this section will most likely be considerably
modified in the future to accomodate devices that may have different
sets of additional valuators than the pressure <structfield>xtilt</structfield>
and <structfield>ytilt</structfield>.
