Hi list,
First of all, my thanks to those involved in the "A couple of quick
questions‏" discussion, its very helpful.
I have another few questions - say my card does not support drawing lines,
Directfb falls back to using software to draw the lines. The final result is
written to the framebuffer mmap. But before being mmap to the framebuffer, is
the line held in a temporary working buffer while clipping or does the software
drawing operation directly manipulates the framebuffer mmap?
If there is such a buffer, where is the buffer defined in the struct CardState
or struct GenefxState? Can this buffer be converted to a blit source for
hardware blitting?
I am using Directfb-1.0 and looked at generic.c but couldnt yet figure out how
genefx drawing works.
thanks,
Nigel
