John, I don't think you can automatically do what you're asking -- a snapshot always "grabs" from a rectangle.
You either need to do as Andre suggests, or you have to define the L region yourself, and mask it out of the snapshot image. You can do this using a combination of ink effects, or by artificially applying alpha transparency to the snapshot. There are probably a few other ways as well. Here's an example of masking using ink effects: go url "http://tactilemedia.com/site_files/downloads/masking_options.rev"; Here's an example of applying alpha transparency to one image using the imageData of another image: go url "http://tactilemedia.com/site_files/downloads/get_alpha.rev"; Hope this helps.
