I have an NSData buffer with valid JPEG data which I can save to disk using writeToFile: and view the image easily. When I come to create an NSImage object from the same data I get an object returned back from initWithData: but the size property has dumb values. What does this mean? Is this a valid NSImage object?

What are the "dumb" values? The size that an NSImage reports are in points, not pixels, so if the image is recorded as having a DPI other than 72, then you will see values other than the pixel size of the image. -- David Duncan Apple DTS Animation and Printing
