How to make a big graphic window larger than Xwindows size? [message #44700]

Hi all,
Is there any way to make a large direct graphic window in IDL?
Each time I try to use
window,xsize=2000,ysize=2000
I always got a window litter bit than the screen size(1600x1200, ).
The window I can get is " 0: Win(1593,1117, Pixmap) "
The alternative question is how to make a large size figure in IDL?
Thanks very much!

Best wishes,
Charles

From the IDL documentation regarding the Z-buffer device: "The frame
buffer that contains the picture is 8 bits deep and is accessed as
channel 0. The Z depth buffer contains 16 bit integers and is accessed
as channel 1."

So, I if you're trying to use channels in an RGB sense, then what you
said is true.

It seems to me that zbuffer doesn't support mutiple channel, neither
postscript. Is this true?

For displaying large images swindow is great. For using it interactively it would
be nice to have something like "scursor" since the swindow cannot be scrolled while
using the ordinary cursor command.

Have you tried using the Z-buffer instead?

set_plot, 'Z'
device, set_resolution = [2000, 2000]

; do your plotting

image = TVRead() ; see [1]
write_image, filename, format, image

[1] You can find TVRead() in David Fanning's library. It's designed to
be a better replacement of IDL's tvrd().

The best solution is the swindow routine from the JHU/APL library:

ftp://nansen.jhuapl.edu/pub/idl/routines/swindow.pro

IDL> swindow, xsize=2000, ysize=2000

I had a similar problem at work. I ended up using Object Graphics,
needed to create a display and pan window. Then setting VIEWPLANE_RECT
to the size of the display window and using SUB_RECT to display smaller
portion of image.
