2000-10-18 Havoc Pennington <hp@redhat.com> * gtk/gtk-sections.txt: Some updates * gdk/gdk-sections.txt: remove GdkPixbufAlphaMode * gdk-pixbuf/gdk-pixbuf-sections.txt: Add new API, remove GdkPixbufClass/GdkAnimationClass since those are private * gdk-pixbuf/Makefile.am (IGNORE_HFILES): ignore more headers 2000-10-18 Havoc Pennington <hp@redhat.com> * gtk/gtktextiter.c (gtk_text_iter_forward_to_newline): Fix a bug where any number of empty lines would get skipped * gtk/gtktextiter.h: Remove padding from GtkTextIter; live on the edge. * gtk/gtktextiter.c (gtk_text_iter_make_surreal): enhance the warning about invalid iterators (explain more thoroughly) (gtk_text_iter_in_region): rename gtk_text_iter_in_range * gtk/gtktextview.c (FOCUS_EDGE_WIDTH): Make focus rectangle less big * demos/*.c: Add error handling * gtk/gtktextbuffer.c: don't modify const iterators * gtk/gdk-pixbuf-loader.c: Add full error handling here * gtk/gtkimage.c (gtk_image_set_from_file): ignore errors on file load * gtk/gtkiconfactory.c: Update to reflect addition of error handling to gdk-pixbuf loaders 2000-10-16 Havoc Pennington <hp@redhat.com> * gdk-pixbuf-io.c (gdk_pixbuf_get_module) (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module): add error reporting here also * make-inline-pixbuf.c (main): use GError * io-xpm.c: include unistd.h * gdk-pixbuf-util.c: include string.h * io-*.c: add error reporting * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add error reporting * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting * gdk-pixbuf-io.h: Add GError** to load_increment and load methods * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return a G_FILE_ERROR if we fail to write or close the file. * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following the GError naming rules. Add GError** to load functions.

<para>
|
|
The &gdk-pixbuf; library provides a simple mechanism to load and
|
|
represent animations, primarily animated GIF files. Animations
|
|
are represented as lists of #GdkPixbufFrame structures. Each
|
|
frame structure contains a #GdkPixbuf structure and information
|
|
about the frame's overlay mode and duration.
|
|
</para>

|
|
<!-- ##### ENUM GdkPixbufFrameAction ##### -->
|
|
<para>
|
|
Each animation frame can have several things happen to it when the
|
|
next frame is displayed. The #GdkPixbufFrameAction determines
|
|
this. These are essentially the overlay modes supported by GIF
|
|
animations.
|
|
</para>
|
|
|
|
@GDK_PIXBUF_FRAME_RETAIN: The previous image should remain displayed,
|
|
and will potentially be occluded by the new frame.
|
|
@GDK_PIXBUF_FRAME_DISPOSE: The animation will be reverted to the state
|
|
before the frame was shown.
|
|
@GDK_PIXBUF_FRAME_REVERT: The animation will be reverted to the first
|
|
frame.

<!-- ##### STRUCT GdkPixbufFrame ##### -->
|
|
<para>
|
|
This structure describes a frame in a #GdkPixbufAnimation. Each
|
|
frame consists of a #GdkPixbuf, an offset of the frame within the
|
|
animation's bounding box, a duration, and an overlay mode or
|
|
action.

|
</para>

<!-- ##### STRUCT GdkPixbufAnimation ##### -->
|
|
<para>
|
|
This structure describes an animation, which is represented as a
|
|
list of #GdkPixbufFrame structures.
