Actually, as I discovered when I sat down to write
an article about this, the keyword to PS_END is WIDTH,
not IM_WIDTH. You *do* however, set the default values
for the width of raster output with the IM_WIDTH keyword
to cgWindow_SetDefs and cgControl, as described.
Also, when I was writing the article, I thought it would
be a good idea to an an OUTPUT keyword to cgControl, which
can be used to select the specific kind of output you
desire in exactly the same way you would select output
on a cgPlot command. In other words, the OUTPUT keyword
is now a short hand way to set the Create_PNG, Create_JPEG,
Create_PS, etc. keywords to cgControl.
cgControl, OUTPUT='myplot.png'
This new functionality is here:

The article that describes how to set the raster file
width is here:
