copy_from_graphics() [3/4]

void xtd::drawing::graphics::copy_from_graphics	(	const graphics &	source,
		int32	source_x,
		int32	source_y,
		int32	destination_x,
		int32	destination_y,
		const xtd::drawing::size &	block_region_size
	)

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

Parameters

source	The drawing surface of the xtd::drawing::graphics source.
source_x	The x-coordinate of the point at the upper-left corner of the source rectangle.
source_y	The y-coordinate of the point at the upper-left corner of the source rectangle.
destination_x	The x-coordinate of the point at the upper-left corner of the destination rectangle.
destination_y	The y-coordinate of the point at the upper-left corner of the destination rectangle.
block_region_size	The size of the area to be transferred.

Remarks

The xtd::drawing::graphics::copy_from_graphics 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.
