Salut! I'm trying to reproduce a very popular image effect these days, where the image seems to levitate above a reflective ground. So I build a GdkPixbuf and I first render my image on it (which is scaled to fit inside). Then I have to draw the reflection, which is the same image but flipped vertically. To do so I use gdk_pixbuf_composite with a yscale parameter to -1.0. Here is what this does: http://kris.dehais.free.fr/bazar/nearest_and_hyper_(correct).jpg I get different result with different GDK_INTERP value: tiles and bilinear fail to a black rectangle, while nearest and hyper succeed. http://kris.dehais.free.fr/bazar/tiles_and_bilinear_(long_to_generate).jpg Is this something known ? Then: As far as there is no rescaling, I don't need 'hyper' interpolation, but if I want to shrink the reflection to make it a little bit more realistic, then yscale will have != -1.0 values. When I implement that, tiles and bilinear fail again, nearest work as well as it can and hyper produces giltches (removed fading for clearness) http://kris.dehais.free.fr/bazar/rescale+nearest.jpg http://kris.dehais.free.fr/bazar/rescale+hyper_(glitches_on_cheek).jpg Are there any known limitations of gdk_pixbuf_composite I am falling into ? Thanks for clues, Christophe. _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
