No. Chuck developed something called imageFORTH (really an application 
layer on top of Forth) in the late 70's, directed at image processing. 
The basic object was an IMAGE. It had properties (x & y dimensions, 
windows within that range, pixel size, etc.) and methods that could be 
applied to them. There was a current INPUT image and a current OUTPUT 
image, and you could specify multiple methods and then do a PASS which 
would apply the methods to the INPUT image writing it to the OUTPUT 
image (which could be the same place) applying whatever were the 
specified methods. Methods included various kinds of enhancement, 
display, scaling, other things. It was quite sophisticated, and he 
implemented it on a number of different kinds of devices.
