Does anybody know if the raster file generated by the writecanvas primitive 
running under NeWS 2.0 is any different from NeWS 1.1.? If so, what is the
difference.

The reason I ask is that we have noticed a difference in the file sizes
between rester files generated under NeWS 1.1 and the same image generated
under NeWS 2.0. It appears that NeWS 2.0 is compressing it's data.

Here's an example.
Run the following code in an interactive psh under both NeWS's and compare
for your self.

        /xx 300 300 1 [300 0 0 300 0 0] {<00>} buildimage def
        xx setcanvas
        (filename) writecanvas


        Thanks,
        Pablo

P.S. Has any body successfully converted their NeWS 1.1 applications to 
     NeWS 2.0?
