Detailed Description

Abstract Base Class for creating interfaces to import unknown image formats.

The OvImageAdapter base class defines a very basic interface to an image which provides access to the dimensions and datatype of the image, and provides get and set methods to alter image pixels. A class derived from OvImageAdapter must implement the pixel get/set and information methods. Using OvImageAdapter objects, the library allows the user to interface with any image model. See the OpenCVImageAdapter or MatlabImageAdapter subclasses for interfacing examples.

Member Function Documentation

void OvImageAdapter::getDataType

(

OvImageAdapter::OvDataType &

dataType

)

const [virtual]

Returns data type of image.

Parameters:

dataType

data type of image (from enum OvDataType)

See also:

OvDataType

virtual double OvImageAdapter::getPixel	(	int	row,
		int	column,
		int	channel
	)			const [pure virtual]

Returns a pixel value at a particular row, column and color channel. This is a pure virtual function.

Parameters:

	row	row of the image
	column	column of the image
	channel	channel of the image

Returns:

pixel value (type double)

Implemented in MatlabImageAdapter, and OpenCVImageAdapter.

void OvImageAdapter::getSize	(	int &	height,
		int &	width,
		int &	nColorChannels
	)			const [virtual]

Returns height, width and number of color channels of image.

Parameters:

	height	height of image
	width	width of image
	nColorChannels	number of color channels of image

virtual void OvImageAdapter::setPixel	(	double	value,
		int	row,
		int	column,
		int	channel
	)			[pure virtual]

Sets a pixel value at a particular row, column and color channel. This is a pure virtual function.

Parameters:

	value	value to be set
	row	row of the image
	column	column of the image
	channel	channel of the image

Implemented in MatlabImageAdapter, and OpenCVImageAdapter.
