Thanks, that was the step I'd missed (sort of obvious in hindsight!).

Thanks also to Marcel who pointed out the same thing.

If you create image data of Type jpeg, tiff, png, etc from a sourceRep (NSBitMapImageRep) with -representationUsingType:properties: these data contain the number of pixels *and* the resolution of the sourceRep. If you want a special resolution you have to set that value in the sourceRep. But you can't set the resolution directly in NSBitMapImageRep with something like -setResolutionX:resolutionY: You have to set the size of the rep!
