I am trying to read a .png file, modify it and write a back to the file system.  In order to do that, my understanding 
is, that I need to use both gf and img libraries.  I don't want to use any specific HW to attach to as I don't need to 
display my .png file.  All I want to do is to be able to create surface so that I can modify my .png file.

In order to create a surface, I need to first attach to a device.  My understanding is that I can use devg-flat as a 
device.  However I am not sure, how to install devg-flat driver and related files into my IDE and target.  I also don't 
know how to use devg-flat in the call gf_dev_attach() call?  I have already added libffb.so to extra libraries section 
of IDE.

I appreciate it if anyone can give me some pointers on this.

Regards,

Reza.
