void xtd::drawing::graphics::copy_from_screen	(	const xtd::drawing::point &	upper_left_source,
		const xtd::drawing::point &	upper_left_destination,
		const xtd::drawing::size &	block_region_size
	)

Performs a bit-block transfer of color data, corresponding to a rectangle of pixels, from the screen to the drawing surface of the xtd::drawing::graphics.

upper_left_source	The point at the upper-left corner of the source rectangle.
upper_left_destination	The point at the upper-left corner of the destination rectangle.

Remarks

The xtd::drawing::graphics::copy_from_screen methods are useful for layering one image on top of another. To specify how the source and destination colors are blended, use one of the xtd::drawing::graphics::copy_from_screen methods that takes a xtd::drawing::graphics::copy_pixel_operation parameter.
