Detailed Description

Image region operations.

Member Enumeration Documentation

enum VRS::ImageRegionOp::Operation

Enumerator:

Flip
Blur
Mosaic

Constructor & Destructor Documentation

VRS::ImageRegionOp::ImageRegionOp	(	int	opType,
		int	value1,
		int	value2
	)

A region-operation object encapsulate one region-operation applied to a source image. Most operation types require two parameters, which can be set separately. The region-operation object can form part of an operation seuquence, e.g., ManipulatorList. All operations are accessible also as static methods which can be invoked directly. The Image class contains methods which access the region oerations in a more convienent way.

(

Operation

)

void VRS::ImageRegionOp::setOperation

(

int

opType

)

int VRS::ImageRegionOp::getOperation

(

)

const

Sets/returns the operation type of the pixel-operation object.

void VRS::ImageRegionOp::setValue	(	int	valueNo,
		int	value
	)

int VRS::ImageRegionOp::getValue

(

int

valueNo

)

const

Sets/returns the parameter value used by the operation. The parameters are defined as follows for the operations: flip: 2 parameter, horizontal flag, vertical flag blur: 2 parameter, size x, size y mosaic: 2 parameter, size x, size y grey-scale: no parameter

virtual Image* VRS::ImageRegionOp::manipulate	(	Image *	srcImage,
		Image *	dstImage
	)			[virtual]

The image operation is apply to the source image and the the resulting image is stored in the target image. The handle of the target image is returned.

Implements VRS::ImageManipulator.

virtual bool VRS::ImageRegionOp::operatesInPlace

(

)

const [virtual]

See `ImageManipulator'. This manipulator can operate in place.

Reimplemented from VRS::ImageManipulator.

static void VRS::ImageRegionOp::flip	(	Image *	srcImage,
		Image *	dstImage,
		int	flipX,
		int	flipY
	)			[static]

If flipX is set, the image is flipped horizontally. If flipY is set, the image is flipped vertically.

static void VRS::ImageRegionOp::blur	(	Image *	srcI,
		Image *	dstI,
		int	sizeX,
		int	sizeY
	)			[static]

Replaces the pixel value by the average pixel value of its neighborhood.

static void VRS::ImageRegionOp::mosaic	(	Image *	srcI,
		Image *	dstI,
		int	sizeX,
		int	sizeY
	)			[static]

Tiles the image into blocks of sizeX x sizeY. Replaces the pixel value within a block by the average pixel value in the block.
