CopyPixel:Void src_x:Int32, src_y:Int32, src_buffer:Int32, dest_x:Int32, dest_y:Int32, dest_buffer:Int32=0

Parameter	Mode	Type	Default	Description
src_x	In	Int32	required	Horizontal position of the pixel to copy.
src_y	In	Int32	required	Vertical position of the pixel to copy.
src_buffer	In	Int32	required	The buffer to copy from.
dest_x	In	Int32	required	Horizontal position to copy to.
dest_y	In	Int32	required	Vertical position to copy to.
dest_buffer	In	Int32	0	The buffer to copy to. Defaults to the current buffer.

Description

Copies one pixel from a buffer to another, or inside the same buffer. Each call has to work out where both pixels are, so for many pixels lock the buffers and use CopyPixelFast.

Differences

• A source pixel outside of its buffer is read as 0 (black), and a destination outside its buffer is skipped.
• Pixels are copied with all the bits that the buffers have: a buffer made by Graphics3D with the depth 64 does not lose anything on the way. See Color depth.
