Thanks Karl for giving the right pointers. Xobjview works the best for
the application that I am developing. By the way, I'm not sure if this
is a bug in Xobjview - when I export the image into .TIFF (using
file->export) and later open with a Tiff editor, the image is
"FLIPPED". It gets exported just fine if exported as .JPEG !

Any Comments?

PS: David, I'm working on it, and as soon as I understand and reproduce
the iImage mountain of code I'm planning to start-up "VDL" (Victor's
Data Language) ;-) Thanks 2 all
