plot and page size

Dear ncl users:

The archives detail a great deal of discussion regarding the gsn
resources, particularly the ones that pertain to page size/ plot
maximization. Despite all the talk on this matter, I'm still having a
lingering, yet simple issue with my .ps files and their orientation.
Using only the resource function gsnMaximize, my plot is fitted to the
postscript sheet. However, it is then oriented sideways on my screen. I
understand that you can then use the function gsnPaperOrientation to set
the sheet to a portrait orientation, but then there is a huge white area
both above and below my plot filling the rest of the page, which
eliminates the alteration performed by the gsnMaximize function. I have
tried using the gsnPaperWidth and gsnPaperHeight functions to alter this
large whitespace, but they do not seem to work. It's at this point that
the archived discussion doesn't help address this issue. Can anyone
help? I would rather not use some secondary software package (ie
imagemagick) to rotate the image, since it often leads to resolution
reductions. Thanks!
