[directfb-dev] Re: Help me please! About 4bits pixel format.

Quoting James Su (

data->area.current.(x/y) contains the offset the sub surface relative
to the beginning of the whole surface. I think restricting sub surfaces
to even x coordinates is ok. The problems related to DFB_BYTES_PER_PIXEL
should be eliminated using DFB_BYTES_PER_LINE with the x offset.
