I have a couple of postscript saving examples
that include the following geometry parameters
which produce .ps files that render the same
as the canvas drawings when viewed in ghostsript.
retval = canvas.postscript(
file = "image/ps/xyzzy.ps ,
height = 400 ,
width = 400 ,
pagewidth = 400 ,
pageheight = 400 ,
colormode = "color" )
Perhaps adding the geomerty parameters
might help.
