For a true WYSIWYG grab that may be exactly what's needed, but if you want to grab only a specific window, or even an object within that window, without anything else in the image, you can use the "export from " form introduced in v2.7. Oddly enough, stacks cannot be used as the referenced object, so this won't work: export snapshot from this stack to file myFile But cards can, so this will work: export snapshot from this cd of this stack to file myFile With v2.7 Mark Waddingham did a massive overhaul to the way objects are rendered in order to better accommodate modern OS buffering schemes along with antialiasing and more, and thankfully implemented it in a way that exposes those buffers to us with this new option for "export snapshot". The engine still supports the grab from the general display buffer by specifying a rect, which will then grab it from the OSes master display which includes all windows. But if you need to render just a specific object, you can trigger Rev's internal buffering routines to create a buffer into which it will render that for you and hand you the resulting image data, using the "...from " option. Which is better will of course depend on what you want to do. But it can be handy for Paul to know both forms to pick the one that works best for what's needed. His original attempt at using "this window" was very close; just changing that to "this cd of this stack" should do what he was looking for. -- Richard Gaskin Fourth World Revolution training and consulting: http://www.fourthworld.com Webzine for Rev developers: http://www.revjournal.com ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

put specialFolderpath("desktop") & "/test.png" into myFile
There are lots of great, short scripting examples, like this one, that
show up here on the list. My I suggest that whenever you submit one
you also consider submitting it as a User Note to the appropriate
dictionary entry in Rev 3.5. It is real-world examples like this that
are lacking in many dictionary entries, and they would make the
dictionary a much more valuable tool.
In this particular example, I remember the first time I used export
snapshot. It took me quite a bit of fiddling and searching the list
archives until I finally got it. This script would have clarified it
for me in a fraction of the time.
Regards,
Devin
P.S. Mark and Jacque, with your permission, I'll be happy to submit
your combined example.

Re: Help on export snapshot
2 problems as far as I can see: 1. You need to fiddle around with set default folder e.g: set the defaultFolder to /HD/Users 2. export snapshot to file "experiment.png" as PNG (i.e. not as scrambled eggs) Paul Gabel wrote: Hello list: Can anyone help me on exporting a snapshot by script.
