* Makefile.am (SRC_SUBDIRS): contrib subdir
* gdk/gdkpixbuf.h: Move GdkPixbufAlphaMode to gdk-pixbuf library,
so it can be used in Xlib version
* demos/testpixbuf.c (update_timeout): error checking from 1.0
tree
* gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_get_pixbuf): Sync
change from 1.0 tree that returns first frame of animation
if the loaded file is an animation.
* contrib: add new directory to hold stuff that comes with GTK+
but isn't really part of GTK+ (for now, gdk-pixbuf-xlib)
* configure.in: add contrib/*

This entry is a summary of the merged-in changes from 1.0.
Relevant original ChangeLog entries are spliced in after
this entry; the files they refer to are from the 1.0
gdk-pixbuf sources.
* pixops/pixops.c (pixops_composite_nearest): sync a small fix
from 1.0
* io-xpm.c (xpm_seek_string): add fscanf error check from 1.0
Add progressive loader from 1.0
* io-tiff.c (gdk_pixbuf__tiff_image_begin_load): mem leak fixes
from 1.0 tree
* io-pnm.c: new version from 1.0 tree
* io-jpeg.c (gdk_pixbuf__jpeg_image_load): sync from 1.0, use
malloc not g_malloc
* io-gif.c (lzw_read_byte): sync from 1.0, change a g_error to
g_warning
(gif_get_next_step): return 0 here, sync from 1.0
* gdk-pixbuf-util.c: sync email address change for Cody
Russell
2000-09-11 Jeffrey Stedfast <fejj@helixcode.com>
* gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
last nights code was still "broken". Should now properly handle
all error conditions gracefully.
2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
* gdk-pixbuf/io-pnm.c: Rewrote.
2000-09-09 Federico Mena Quintero <federico@helixcode.com>
* gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): Compute
the correct dest offset.
2000-08-25 Federico Mena Quintero <federico@helixcode.com>
* gdk-pixbuf/io-xpm.c: #include <unistd.h>
2000-08-05 Larry Ewing <lewing@helixcode.com>
* gdk-pixbuf/io-tiff.c: stop leaking context->tempname.
* gdk-pixbuf/io-xpm.c: same as above.
2000-07-26 Michael Meeks <michael@helixcode.com>
* gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_load): make
g_malloc a malloc.
2000-07-21 Larry Ewing <lewing@helixcode.com>
* gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
xpm at least supports the progressive interface like the one in
io-tiff.c. This should be reimplemented as an actual progressive
loader.
2000-07-19 Jonathan Blandford <jrb@redhat.com>
* demo/pixbuf-demo.c (update_timeout): changed scaling level to
make it look better.
* gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael
meeks to handle errors better.

Functions for rendering RGB buffers to X drawables.

<!-- ##### SECTION Long_Description ##### -->
|
|
<para>
|
|
The XlibRGB set of functions is a port of the GdkRGB library to
|
|
use plain Xlib and X drawables. You can use these functions to
|
|
render RGB buffers into drawables very quickly with high-quality
|
|
dithering.

<!-- ##### ENUM XlibRgbDither ##### -->
|
|
<para>
|
|
These values are used to specify which dithering method should be
|
|
used. <symbol>XLIB_RGB_DITHER_NONE</symbol> will use no dithering
|
|
and simply map the colors in an RGB buffer to the closest colors
|
|
that the display can provide.
|
|
<symbol>XLIB_RGB_DITHER_NORMAL</symbol> will provide dithering
|
|
only on pseudocolor displays.
|
|
<symbol>XLIB_RGB_DITHER_MAX</symbol> will provide dithering on
|
|
pseudocolor and 16-bit truecolor or “high color”
|
|
displays.
|
|
</para>
|
|
|
|
@XLIB_RGB_DITHER_NONE: Specifies no dithering.
|
|
@XLIB_RGB_DITHER_NORMAL: Specifies dithering only on pseudocolor
|
|
displays.
|
|
@XLIB_RGB_DITHER_MAX: Specifies dithering on high color displays.
