Hi,
Using "set_plot = ps" I created a ps file.
I'm trying to resize the ps image and add some text (such as Figure1.
~~~) in my word text of lab paper.
How do I take the ps file and add text into it?
Thanks.

In general, any time you issue a graphics command that
would, on your display, erase the window first (e.g, Plot,
Contour, Surface, etc.) will, in PostScript, create a new
page of output. Any time you issue a graphics command
that would go into the same window (e.g. OPLOT, PLOTS,
XYOUTS, etc.) will stay on the same page.
Moreover, you can force a new page of PostScript output
by "erasing" the window with an ERASE command.
Cheers,
David

============================================================ =
Sorry,my statement might be ambiguous so David did not understand.
Let me give an example to explain.
Everybody must have seen some large geographical map(such as a US
geographical map with scale 1:10000).I can use IDL and
"set_plot,'ps'"command to produce such a ps file.But it is too
large and nobady can watch it on monitor or print it by printer.
Now,I want to produce the same map with the same scale,but change
the map into to a book with A4 size per page.We can watch that book or
print that book whatever size the US map is.
My question is how can I make out that ps-book in an IDL procedure and
its set_plot command.
Thanks
