GraphicsMagick for iPhone development

I want to use image manipulation functi开发者_C百科onality from GraphicsMagick for my iPhone app, but I'm finding it quite hard to locate good instructions to set up the library, and sample code for how to use it in Objective-C. Do such instructions or code exist?

Try the this tool for compilation: http://sourceforge.net/mailarchive/forum.php?forum_name=graphicsmagick-tools&max_rows=25&style=nested&viewmonth=201109

For me GraphicsMagick is performing far better than ImageMagick.

GraphicsMagick is it available for iOS or Mac Os X? You can try Some Apple's sample like GLImageProcessing and some sample source on github and google svn for objective-c image processing.
