* gtk/gtkiconfactory.c:
* gtk/gtkitemfactory.c: use gdk_pixbuf_new_from_stream(). fixed up
item factory so inlined pixbufs actually work.
Tue Jun 26 09:48:02 2001 Tim Janik <timj@gtk.org>
* Makefile.am (noinst_PROGRAMS): get rid of make-inline-pixbuf
* gdk-pixbuf-data.[hc]: provide gdk_pixbuf_new_from_stream()
instead from gdk_pixbuf_new_from_inline().
* gdk-pixdata.[hc]: auxillary GdkPixdata structure, public
installed API for applications that need to serialize/deserialize
on their own (gimp, BEAST).
* gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
program that can dump images in CSource format and Pixbuf
stream format. supports RLE encoding, MACRO formatting etc...
invoke with --help.

<!-- ##### 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.
