Is there a way to get the Raster Image Files vis ImageMagick from the graphics window or do I need to just save as a postscript and manually convert the file in ImageMagick? I'm using IDL version 8.1.0 on a mac.

David,

I will certainly take a look at that article. The quality of the output is alright. The problem is I can only save from the graphics window to a postscript and the hardcopy created is different looking then the cgWindow (axis label spacing too close to graph, legend too big, and panel spacing too close). I've tried to save as a Raster File but for some reason nothing is generated and either IDL or my mac actually deletes any previously saved .ps files from cgWindow of the same name. I think the legend resizing problem might be because I used AL_legend,['1500 m', '2000 m', '2500 m', '3000 m', '3500 m'], psym=[28,28,28,28,28], color=['red', 'blue', 'green', 'cyan', 'magenta'], pos=[0.055,0.96], /norm, charsize=0.85. This seemed to be the only method that worked to produce a legend in each panel though. Is there a better way to do that so it doesn't change size in the hardcopy? Maybe not use normalized positions. Thanks.
