I was wondering if there are any resources for composing PNG images in Cocoa.

Just compose in an NSImage (srcImage) :

NSBitmapImageRep *imageRep = [NSBitmapImageRep imageRepWithData: [srcImage TIFFRepresentation]]; NSData *pngData = [imageRep representationUsingType: NSPNGFileType properties: nil];

Now you have the PNG version of the image stored in an NSData to do with as you please. You can, of course, create an NSDictionary to define the properties to use when creating the PNG.. look in the doc for NSBitmapImageRep for more info...

(Note - untested code, I make no warranties of any kind =) )
