Member Function Documentation

calculate()

bool QgsRasterCalcNode::calculate	(	QMap< QString, QgsRasterBlock * > &	rasterData,
		QgsRasterMatrix &	result,
		int	row = -1
	)		const

Calculates result of raster calculation (might be real matrix or single number).

Parameters

rasterData	input raster data references, map of raster name to raster data block
result	destination raster matrix for calculation results
row	optional row number to calculate for calculating result by rows, or -1 to calculate entire result
