Re: how to change the page size of pdf?

Hi,

I believe that setting gsnPaperMargin is the easiest way you can get
rid of white space, but it obviously doesn't get rid of all of it.

It can sometimes depend on the type of visualizations you are
doing, and whether you are paneling plots. If you are doing paneling,
then there's a couple of panel resources you can use
(gsnPanelXWhiteSpacePercent and gsnPanelYWhiteSpacePercent) to control
white space.

The other thing that might work to trim white space is to use the
"-trim" option with the ImageMagick tool "convert"
(http://www.imagemagick.org/script/index.php). I use this tool to
convert my PS/PDF files to png *and* to trim the white space for usage
on web pages and PowerPoint presentations.

If you are able to provide us with your data and script, we can try
running it here and suggest ways to decrease the white space.
