* 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.
