Parameters

Left: The x-coordinate of the upper-left point of the region of interest, in pixels, measured from the upper-left corner of the image.
Top: The y-coordinate of the upper-left point of the region of interest, in pixels, measured from the upper-left corner of the image.
Width: The width of the region of interest, in pixels.
Height: The height of the region of interest, in pixels.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK.

We strongly recommend always checking this status first.
