LT_STATUS LTICropFilter::initialize	(	LTIImageStage *	srcImage,
		lt_int32	xOffset,
		lt_int32	yOffset,
		lt_int32	newWidth,
		lt_int32	newHeight
	)

Creates an image stage which corresponds to a cropped subsection of the input image, according to the given offset, width, and height.

Parameters

srcImage	the base image
xOffset	x-position of the origin of the new image (specified relative to the input image)
yOffset	y-position of the origin of the new image (specified relative to the input image)
newWidth	width of the new image
newHeight	height of the new image
