Not sure what you mean by the "values" of the image. The pixel values? Not unless you already have an NSData for the data. If you want to manually set pixel values, it looks like you'll have to go all the way down to the CG level and create a CGBitmapContext.
Yea I might have to do that. Its just that the ints are declared in the .h and I had planned to put all the value assignment bits in the initialization.
