Detailed Description

Pansharpening operation class.

Constructor & Destructor Documentation

GDALPansharpenOperation::GDALPansharpenOperation ( )

default

Pansharpening operation constructor.

The object is ready to be used after Initialize() has been called.

GDALPansharpenOptions * GDALPansharpenOperation::GetOptions ( )

Return options.

CPLErr GDALPansharpenOperation::Initialize ( const GDALPansharpenOptions * psOptionsIn )

Initialize the pansharpening operation.

Parameters

psOptionsIn pansharpening options. Must not be NULL.

CPLErr GDALPansharpenOperation::ProcessRegion	(	int	nXOff,
		int	nYOff,
		int	nXSize,
		int	nYSize,
		void *	pDataBuf,
		GDALDataType	eBufDataType
	)

Executes a pansharpening operation on a rectangular region of the resulting dataset.

The window is expressed with respect to the dimensions of the panchromatic band.

Spectral bands are upsampled and merged with the panchromatic band according to the select algorithm and options.

Parameters

nXOff	pixel offset.
nYOff	pixel offset.
nXSize	width of the pansharpened region to compute.
nYSize	height of the pansharpened region to compute.
pDataBuf	output buffer. Must be nXSize * nYSize * GDALGetDataTypeSizeBytes(eBufDataType) * psOptions->nOutPansharpenedBands large. It begins with all values of the first output band, followed by values of the second output band, etc...
eBufDataType	data type of the output buffer
