Encrypt image in c

[maqableh]

I am trying to read an image in c language and store it in 2d matrix, then I need to do some manipulations (as encryption process) on it and then to show the new image.

Could anyone send to me the code?
Thanks very much.

Try looking up array manipulations (maybe under array translation) in an advanced algebra, calculus or statics & dynamics text book. They should give you some good manipulation techniques for that application. There is a name for it, but it escapes me at the moment and I can't remember, but I think it's in a calculus textbook.
