GrabImage:Void image:Int32, x:Int32, y:Int32, frame:Int32=0

Parameter	Mode	Type	Default	Description
image	In	Int32	required	The image to copy into.
x	In	Int32	required	Left edge of the part of the buffer to copy.
y	In	Int32	required	Top edge of the part of the buffer to copy.
frame	In	Int32	0	The frame to copy into. Defaults to 0.

Description

Copies a part of the current buffer into a frame of an image. The part has the size of the image and starts at the given position, so this is the way to take a screenshot into an image or to build a sprite from something that was drawn.

Differences

• Parts that lie outside of the buffer are not copied and keep what the frame had before.
