* gtk/gtkbindings.c (gtk_binding_set_add_path): to compare pattern
specs, use g_pattern_spec_equal() instead of direct field accesses.
upon compressing two equal paths of the same type, the resulting
priority has to be the maximum.
* gtk/gtkenums.h (enum): take GTK_PATH_PRIO_MASK out of the
GtkPathPriorityType enum and make it a macro.

The GdkPixbuf Structure

<!-- ##### SECTION Short_Description ##### -->
|

Information that describes an image.

<para>
|
|
The <structname>GdkPixbuf</structname> structure contains
|
|
information that describes an image in memory.

|
<!-- ##### ENUM GdkPixbufError ##### -->
|
|
<para>
|
|
An error code in the #GDK_PIXBUF_ERROR domain. Many &gdk-pixbuf;
|
|
operations can cause errors in this domain, or in the #G_FILE_ERROR
|
|
domain.
|
|
</para>
|
|
|
|
@GDK_PIXBUF_ERROR_CORRUPT_IMAGE: An image file was broken somehow.
|
|
@GDK_PIXBUF_ERROR_INSUFFICIENT_MEMORY: Not enough memory.
|
|
@GDK_PIXBUF_ERROR_BAD_OPTION: A bad option was passed to a pixbuf save module.
|
|
@GDK_PIXBUF_ERROR_UNKNOWN_TYPE: Unknown image type.
|
|
@GDK_PIXBUF_ERROR_UNSUPPORTED_OPERATION: Don't know how to perform the
|
|
given operation on the type of image at hand.
|
|
@GDK_PIXBUF_ERROR_FAILED: Generic failure code, something went wrong.
|
|
|
|
<!-- ##### MACRO GDK_PIXBUF_ERROR ##### -->
|
|
<para>
|
|
Error domain used for pixbuf operations. Indicates that the error code
|
|
will be in the #GdkPixbufError enumeration. See #GError for
|
|
information on error domains and error codes.
|
|
</para>
|

|
|
<!-- ##### ENUM GdkColorspace ##### -->
|
|
<para>
|
|
This enumeration defines the color spaces that are supported by
|
|
the &gdk-pixbuf; library. Currently only RGB is supported.
|
|
</para>
|
|
|
|
@GDK_COLORSPACE_RGB: Indicates a red/green/blue additive color space.
|
|
|
|
<!-- ##### ENUM GdkPixbufAlphaMode ##### -->
|
|
<para>
|
|
These values can be passed to
|
|
gdk_pixbuf_render_to_drawable_alpha() to control how the alpha
|
|
chanel of an image should be handled. This function can create a
|
|
bilevel clipping mask (black and white) and use it while painting
|
|
the image. In the future, when the X Window System gets an alpha
|
|
channel extension, it will be possible to do full alpha
|
|
compositing onto arbitrary drawables. For now both cases fall
|
|
back to a bilevel clipping mask.
|
|
</para>
|
|
|
|
@GDK_PIXBUF_ALPHA_BILEVEL: A bilevel clipping mask (black and white)
|
|
will be created and used to draw the image. Pixels below 0.5 opacity
|
|
will be considered fully transparent, and all others will be
|
|
considered fully opaque.
|
|
@GDK_PIXBUF_ALPHA_FULL: For now falls back to #GDK_PIXBUF_ALPHA_BILEVEL.
|
|
In the future it will do full alpha compositing.
|
|
|
|
<!-- ##### STRUCT GdkPixbuf ##### -->
|
|
<para>
|
|
This is the main structure in the &gdk-pixbuf; library. It is
|
|
used to represent images. It contains information about the
|
|
image's pixel data, its color space, bits per sample, width and
|
|
height, and the rowstride or number of bytes between rows.
