Hi Antonio,
Thank you! Just to clarify Bottom Up orientation for a picture of 3,3
pixels I would specify the Red intensities of the following coordinates in
order:
(3,3),(3,2),(3,1),(2,3),(2,2),(2,1),(1,3),(1,2),(1,1) and then followed by
the Green and then Blue in the same sequence.
Is that correct?
Thanks,
Milind
