No, I see a difference using the thick keyword. But, I am used to
writing code like this to make a line proportionately as thick in the
PostScript device.
thick = (!D.Name EQ 'PS') ? 6 : 2
The difference between PostScript "thickness" and display "thickness"
appears to be taken care of automatically, so that a line that is twice
as thick on the display is proportionately twice as thick in PostScript.
But, as far as I can tell, there is no way to do something like this:
thick = (!D.Name EQ 'PS') ? 10 : 2
And make the line *extra* thick in PostScript.
I actually like the way this works, but I just wanted to be sure there
was no programmable way to control it.
With regard to pixelated PNG files, this sounds about right. I don't
know how to apply the "fix" to my Windows machine, though. :-(
Cheers,
David
