Image processing in Cocoa

[gabon]

Hi guys, does anyone has some hints on doing image processing with iPhone SDK? Do I have to use CGImageGetDataProvider?

Thanks, chr

Thanks to this faq: Technical Q&A QA1509: Getting the pixel data from a CGImage object

I found:

CFDataRef data = CGDataProviderCopyData(CGImageGetDataProvider(image));

and data seems to be of the right size, now I have to see how to use it and if to release it (I presume so). It is strange I couldn't find info about CGDataProviderCopyData in the reference.

Cheers, chr
