I found out the reason fbgrab actually does not use the code that comes from the repose but it actually calls
fbcat and the output is piped into png converter.

Hi I am trying to grab images from framebuffer. fbgrab does this perfectly. The fb grab that is installed on ubuntu(the one I installed from the software center) works perfectly. When I compiled the source and run it. THe images are all tilted.
I was getting the same issue before I looked into the source of fb grab.
What could be the issue.
