Hi guys, is there some good tutorial around about how to manipulate
bitmaps in Cocoa?
I would be interested on:
- copy portion of image over another with a mask (this should be
pretty straight forward with quartz2d)
- apply threshold
- apply effects like blur
Not sure if some of this, like the blur, is recommended to do from an
higher level instead of doing it pixel by pixel. In case of the
latter, how to get the bytearray with all the pixels info?
Thanks a lot, chr
