Capture screenshot

Any way to do this? i searched the net and the help files with no avail.
There are two reasons for doing this....
A: I would like to be able to capture screenshots and automatically crop them from inside a program
B: Capturing the screen of another form which would allow the use of gestures "over controls"

Try this library: http://www.b4x.com/forum/additional-libraries/1403-dzimage-library.html

Sahoopes has written a screen capture program using the the dzImage library: http://www.b4x.com/forum/share-your-creations/1897-screen-capture-app.html

Best regards.

Thanks Guys i'll take a look
