I'm having problems trying to chop sprites out of a sprite map. I can
get my first sprite from the top left corner with this:
gdk_pixbuf_composite( sprite_src, sprite_buf,
0, 0, sprite_w, sprite_h,
0.0, 0.0, 1.0, 1.0,
GDK_INTERP_HYPER,
255 );
But then I cannot get my second sprite that is just to the right of
the first one:
gdk_pixbuf_composite( sprite_src, sprite_buf2,
sprite_w, 0, sprite_w * 2, sprite_h,
0.0, 0.0, 1.0, 1.0,
GDK_INTERP_HYPER,
255 );
The first one looks great but I get a black rectangle and a failed
assertion on the second one:
GdkPixbuf-CRITICAL **: gdk_pixbuf_composite: assertion 'dest_x >= 0 &&
dest_x + dest_width <= dest->width' failed
I have tried everything I can think of. Any idea what I'm doing wrong?
Also, I don't actually need to do any scaling, but I cannot currently
find another way to chop sprites out of a sprite map except using the
gdk_pixbuf_composite function. Is there a better way?
Thanks,
