In Xlib there are some functions to capture screen and also heard abt VESA
which is better?
If you are using a frame buffer device, you can capture the contents of
/dev/fb*. Either read from /dev/fb*, or mmap() it. The data you receive are in
the native format of the graphics chip. For CLUT modes, you have to use an
ioctl() to get the colormap.
