pogopogo YaBB Newbies Offline Posts: 5	running from the command line Feb 25th, 2009, 10:28pm   Hello, I'm using Processing to plot thousands of data files as polygons and export them as image files. -I'd like to run this code from a shell script. How can I do that? -Also, can I use PImage to put the polygons on a transparent background? Thanks.

Can I still use mask to make the transparency? I guess I'm confused because I don't really understand how classes work...
