I am not sure to understand you, but should you not use:
ImageReadWriter class>>formFromStream:
Then use Form or BitBlt protocols for your bits manipulations?

I am trying to do some simple image manipulation. Basically, I want to subtract one image from another, to see what's left.
As an experiment, did
aStream := ReadStream on: image1 imageExport. newImageMorph := ImageMorph fromStream:aStream.
Unfortunately, this fails because there is no subclass to handle the binary stream. I couldn't find a way to specify what format the image was in. Does anyone know how to do this?
