I have been trying to use the convert program to trim the white space around the edge
of the hysplit plots using the ImageMagik 'convert -trim' command. This seems to have
no effect on the image. The '-crop IxJ' option has limited success. Is this an
underlying issue with the .ps files that trajplot and concplot create?
The latest versions of Imagemagick changed the cropping function. Instead of
-crop 0x0 use -trim +page
