What you want is to use pixman_composite_glyphs_no_mask() with a LERP_SRC operator. Whilst we have the fast glyph routines, the linear interpolation operator is still incomplete. You can take a look at an old patch here: http://cgit.freedesktop.org/~ickle/pixman/commit/?h=lerp&id=1ace0cf5a1983c7fc96a343379acffbc36efb61e I just need to bring it up to date and see if it remains beneficial. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Pixman mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/pixman
