Re: Why doesn't GTK+ use RLE for the stock icons?

oh, I think I've found the answer myself in the GTK+ documentation:

  GTK+ ships with a program called gdk-pixbuf-csource which allows for
  conversion of GdkPixbufs into such a inline representation. In
  almost all cases, you should pass the --raw flag to
  gdk-pixbuf-csource. For the typical case where the inline pixbuf is
  read-only static data, you don't need to copy the pixel data unless
  you intend to write to it, so you can pass FALSE for copy_pixels.
  (If you pass --rle to gdk-pixbuf-csource, a copy will be made even
  if copy_pixels is FALSE, so using this option is generally a bad
  idea.)

So, using the --rle flag probably only makes sense if disk-space is
very low.



Salut, Sven
