Snapshot command and non-rect polygon selections?
Hi All! Is it possible to to use non rectangular shapes when creating snapshots? What if I had capture shape like the capital letter L ... could I create a snapshot out of the outline of the letter L? (That's just an example...) As I understand it, snapshot only works with four coordinates, the points of a rect... or can they work with any group of points on a polygon? Thanks in advance!

John export snapshot from graphic L to file l.png as PNG will do as you want. No need for coords, just pass the object reference. best andre On Wed, Jun 29, 2011 at 3:48 PM, John Patten johnpat...@mac.com wrote: Hi All!

Hi Andre... The issue is the L shape is inside a larger image. So essentially I only want a part of the image and the part I want is in the shape of the letter L. Thanks!

Re: Snapshot command and non-rect polygon selections?
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.
