CudaImage<float> cudaCrop	(	const CudaImage< float > &	src,
		const Rectangle &	rect,
		const bool	zerofill = false
	)

Overload of crop() using a Rectangle instead of a Point2D<int>+Dims.

Definition at line 73 of file CudaCutPaste.C.

References cudaCrop(), Rectangle::height(), Rectangle::left(), Rectangle::top(), and Rectangle::width().

CudaImage<float> cudaCrop	(	const CudaImage< float > &	src,
		const Point2D< int > &	upperLeft,
		const Dims &	size,
		const bool	zerofill = false
	)

Extract a subimage from the input image.

The upper left corner of the subimage is given by a Point2D<int>, and the size of the subimage is given by the Dims. If zerofill is false, then the rectangle given by Point2D<int>+Dims must be wholly contained within the bounds of the input image. If zerofill is true, then any output region that lies outside the bounds of the input will be zero-filled (where zero means the default value for type T).
