Is it possible to use Gdk drawing functions (gdk_draw_arc(),
etc.) to draw images of higher depth than system and save
I can save GdkPixbufs. If there were drawing primitives in
gdk-pixbuf, it would be everything I need. However I can
draw only on GdkDrawables.
To use gdk_pixbuf_get_from_drawable() I need a colormap.
To create a colormap I need a visual.
And I can get only visuals with depths returned by
gdk_query_depths(), that is system visual. If it's 16 or
even 8 bpp, I have to use that.
Or is there any other method to draw true color images?
(Except using other libraries like Cairo, which currently is
no option for me).
A: Because it messes up the order in which people normally read text.
