Thanks Bob. But what I want is to make something like image processing tool,
where the GUI is developed on Squeak, while the image processing stuff
itself is (hopefullly) done by primitives.
So the first step is to find if there is any method for a primitive to
render an image directly into a window on Squeak environment.
For example, if you send a message
(doit is a method that call the primitive)
then the corresponding primitive will then periodically render an image read
from the file, one image in every 1 sec, for example.
Is it possible ?
