Hi - I'm writing a texture atlasser and so far I have created an NSImage and composited by sub-images onto it using:
-[NSImage drawAtPoint:fromRect:operation:fraction] Now as I understand it the way to save the resulting NSImage to a PNG file is to get the images 'representations' and and save one of them to a file. Trouble is, my resulting NSImage only has one representation which is of type NSCGImageSnapshotRep This type seems to private for some reason and pretty much undocumented. Whenever I try to save this to PNG using various pieces of sample code I get runtime errors like this *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSCGImageSnapshotRep representationUsingType:properties:]: unrecognized selector sent to instance 0x103107d30' Can anyone point me in the right direction as to how to save my NSImage to a PNG file ? Or some documentation which actually describes how to convert the NSCGImageSnapshotRep into something I can save out ? I've spent a few hours on this now and I can't believe there isn't an easy solution I'm missing.
