Hi all-
I was wondering if someone could explain to me why the postscript
device behaves in a certain particularly strange way. I've been
trying to size and position a plot for print-out using the following
code, which will leave the offsets incorrectly set as their default
values:
device,filename='plot.ps',/inches,xoffset=3,yoffset=2,xsize= 5,ysize=5
When I print out the postscript file, the plot sits on the bottom left
corner of the page, as if I hadn't set the xoffset and yoffset
keywords at all. However, the following code works fine:
device,filename='plot.ps',/inches,xsize=5,ysize=5,xoffset=2, yoffset=3
What I'm wondering is why on earth the device procedure cares about
the order of the parameters. I'm not aware of any other IDL
procedures that behave this way. Is there some reason why it does, or
is it some kind of bug in IDL 6.3?
Thanks for any insight anyone can provide.

Without using PSCONFIG, you mean. ;-)

If I read it correctly, there two lines have different parameters too:
xoffset=3, yoffset=2
xoffset=2, yoffset=3 .
How you set up offsets depends on the layout of your figures. I mean
portrait or landscape. You could find more on manual. I do agree with
you it takes some time to figure these things out and get a nice
figure.
