Hi All,
 
I would like to read a Image data already present in the framebuffer, as
I am new to this , I am finding it difficult to read. I have written one
small application where I want to read Image pixels value which are
present in Frame buffer.
 

You can simply open and read /dev/fb0 and it will dump the framebuffer
in raw format.

cat /dev/fb0 will also do the trick.

Google for a screenshot program for the framebuffer. fbgrab is an example.
