Coping a part of an image in C++

manolakis · 09-24-2007, 06:45 AM

Hello all
I am really interested to make a program in C++ that copies a part of a .png image.
So is it any function that will return the image in a [N][M]array of pixels or whatever?
N & M stands for the maximum length of the row or the column.
What afterwards want to do is to copy up to [N-100][M] and return a new image.
Any help will be really nice.

Thanks

Use libpng. Don't reinvent the wheel
