Hello,
I am currently using coyote plotting routines. I wanted to make 3 plots each on first and second pages with same figure filename. Right now, I am plotting 3 plots on page and other 3 plots on another page with different filenames. Is there a simple way with !P.Multi tool in IDL to include multiple pages with same figure filename?
-------------------
Figfile1='figure1.ps'
cgPS_Open, FigFile1
cgDisplay,1200,1000
!P.Multi=[0,1,3]
...
...
...
!P.Multi=0
cgPS_Close
cgPS2Raster,FigFile1,/PNG, Width=1000
FigFile2='figure2.ps'
cgPS_Open, FigFile2
cgDisplay,1200,1000
!P.Multi=[0,1,3]
...
...
...
!P.Multi=0
cgPS_Close
cgPS2Raster,FigFile2,/PNG, Width=1000
--------------------------
Thanks in advance!

I don't think you can have multiple pages in a PNG file.
Non-encapsulated postscripts are fine though, so just keep plotting.
e.g.
cgPS_Open, 'figure1.ps'
cgDisplay,1200,1000
!P.Multi=[0,1,3]
FOR i=0,5 DO cgPlot, [0,1]
cgPS_Close

Yes, this is correct. Creating multiple pages of PostScript output is as
simple as plotting on your display. Any command that would "erase" the
display on your screen before plotting will create another page of
PostScript output. There is no limit to the number of pages created. (To
manually "go to" the next page in a PostScript file, you can simply use
the cgErase command.)
The problem is converting that PostScript file into raster output.
ImageMagick is powerful, and it is possible it might be able to handle a
multipage PostScript file to do the conversion. But, I don't know how to
do that and, right now, I'm not likely to investigate it. I see other
people have tried to do this, with limited success:
