Tristan Van Berkom 1441fc5fb0 Merge branch 'master' into composite-widget-templates 2010-06-07 14:54:08 -04:00
Tristan Van Berkom 67310786cb Made GtkDialog and GtkMessageDialog composite widgets using
gtk_container_class_set_template().
2010-06-07 14:44:17 -04:00
Tristan Van Berkom 0409e5958f Made the default minimum wrap width larger for the sake of default dialog
sizes.
2010-06-07 14:43:31 -04:00
Tristan Van Berkom 48d8d2c819 Added semantics to build composite children automatically from an assigned template.
This patch adds gtk_container_class_set_template[_file](),
gtk_container_class_set_connect_func() and the GtkParamSpecComposite
type. Setting the class template will result in GtkContainer building
the instance's children from the template at construct time, composite
properties will be assigned to their composite children by matching
the property names with the child GtkBuildable ids. The exposed connect
function is there to allow language bindings to automatically assign
methods for the interface callbacks when they assign templates to classes.
2010-06-07 14:37:34 -04:00
Tristan Van Berkom 6a8a584a95 Added gtk_builder_expose_object(), gtk_builder_add_to_parent_from_file() and
gtk_builder_add_to_parent_from_string().

Adding the needed GtkBuilder framework for composite containers. First the
expose_object() api is based on the work Marco Diego Aurélio Mesquita did
in bug 447972 with some bugs fixed and things cleared up. Next the
gtk_builder_add_to_parent_from_[file/string]() variants are used to extend
containers inline by adding themselves and letting the builder add the
children defined in a template file.

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:

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.

=== ChangeLog discontinued ===
With the move to git, GTK+ is switching from a ChangeLog file
to relying on commit messages to provide change history. Please
see README.commits for guidance on the expected message format.

* Makefile.am (lib_LTLIBRARIES): link against xlibs
2002-01-25 Federico Mena Quintero <federico@ximian.com>
Merge from gdk-pixbuf stable.
* gdk-pixbuf-xlib-drawable.c (rgb565msb): Fixed the endianness
conversion --- swap the individual 16 bit values instead of taking
everying as a 32 bit value.
(rgb565lsb): Likewise.
(rgb555lsb): Likewise.
(rgb555msb): Likewise.
2001-11-26 Akira TAGOH <tagoh@redhat.com>
* Makefile.am (libgdk_pixbuf_xlib_1_3_la_LDFLAGS):
Added -version-info.
2001-05-19 Havoc Pennington <hp@pobox.com>
* gdk-pixbuf-xlibrgb.c: docs
2001-06-04 Havoc Pennington <hp@redhat.com>
* gdk-pixbuf-xlibrgb.c (xlib_rgb_init): remove C++ comment,
reported by Dan McNichol

* gdk-pixbuf-xlib-2.0.pc.in (Description): fix up description a bit.
2000-10-06 Havoc Pennington <hp@redhat.com>
* gdk-pixbuf-xlib.c: Put display/screen here, instead of in
the main gdk-pixbuf library as it was in 1.0; since the io-xpm
loader doesn't use these variables anymore it should be OK
2000-09-26 Federico Mena Quintero <federico@helixcode.com>
* gdk-pixbuf/gdk-pixbuf-xlib-drawable.c
(gdk_pixbuf_xlib_get_from_drawable): Do not use
gdk_screen_{width,height}(). Thanks to John Harper for pointing
this out.
2000-08-26 Federico Mena Quintero <federico@helixcode.com>
* gdk-pixbuf/gdk-pixbuf-xlibrgb.c: Added API reference docs.
2000-08-25 Federico Mena Quintero <federico@helixcode.com>
* gdk-pixbuf/gdk-pixbuf-xlib-drawable.c (handle_x_error): Return
0.
(xlib_window_is_viewable): Return FALSE in the last case.
* gdk-pixbuf/gdk-pixbuf-xlib-render.c: Updated the inline docs.
* gdk-pixbuf/gdk-pixbuf-xlib.c: Added API docs.
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

<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.
</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.

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.

The &gdk-pixbuf; library provides a simple mechanism for loading

until the image is done loading.

These functions allow to save a #GdkPixbuf in a number of
file formats. The formatted data can be written to a file
or to a memory buffer. &gdk-pixbuf; can also call a user-defined
callback on the data, which allows to e.g. write the image
to a socket or store it in a database.

<!-- ##### 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.

The functions in this section allow you to take the image data

<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,
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.

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

</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
into account when scaling the pixbuf item. If this argument is
%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.

In addition to the normal Gdk-specific functions, the &gdk-pixbuf;
package provides a small library that lets Xlib-only applications
use #GdkPixbuf structures and render them to X drawables. The
functions in this section are used to initialize the &gdk-pixbuf;
Xlib library. This library must be initialized near the beginning
of the program or before calling any of the other &gdk-pixbuf;

<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,
as returned by gdk_pixbuf_get_rowstride(), indicates the number
of bytes between rows.

<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-3.0</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>

Installing a module is a two-step process:

</para></listitem>

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>
<informalexample><programlisting>
GdkPixbufModulePattern *signature[] = {
{ "abcdx", " !x z", 100 },
{ "bla", NULL, 90 },
{ NULL, NULL, 0 }
};
</programlisting>
The example matches e.g. "auud\0" with relevance 100, and "blau" with
relevance 90.</informalexample>

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>
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.

<para>
#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>
<para>
As #GdkPixbuf is derived from #GObject now, gdk_pixbuf_ref() and
gdk_pixbuf_unref() are deprecated in favour of g_object_ref()

<emphasis>Finalizing</emphasis> a pixbuf means to free its pixel

library functions that create #GdkPixbuf structures create the
pixel data by themselves and define the way it should be freed;
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
pixel buffer, you must also specify a way to free that data. This
is done with a function of type #GdkPixbufDestroyNotify. When a
pixbuf created with gdk_pixbuf_new_from_data() is finalized, your
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().

<!-- ##### ENUM GdkInterpType ##### -->
<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.
</para>
<para>
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

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>
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.

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></listitem>

GDK provides functions to determine a number of different

<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.

Graphics Contexts

Objects to encapsulate drawing properties
<!-- ##### SECTION Long_Description ##### -->
<para>
All drawing operations in GDK take a
<firstterm>graphics context</firstterm> (GC) argument.
A graphics context encapsulates information about
the way things are drawn, such as the foreground
color or line width. By using graphics contexts,
the number of arguments to each drawing call is
greatly reduced, and communication overhead is
minimized, since identical arguments do not need
to be passed repeatedly.
</para>
<para>
Most values of a graphics context can be set at
creation time by using gdk_gc_new_with_values(),
or can be set one-by-one using functions such
as gdk_gc_set_foreground(). A few of the values
in the GC, such as the dash pattern, can only
be set by the latter method.
