Hi All,

I'm a new suscriber on the list, from Toulouse (France) :-) and i begin
learned gtk some years ago.

I convert a app for use of gdk-pixbuf instead of imlib and I don't understand
how to render an area of a pixbuf into an another pixbuf, with transparent
regions... I try gdk_pixbuf_copy_area, without success.

gdk_pixbuf_composite make the job, but it's very slow...

So I look for  gdk_pixbuf_render_to_drawable_alpha but with a pixbuf as
destination.

I think I don't understand or miss something essential and so need a little
help for my app...

Thanks,
