Detailed Description

template<class M>
class rack::DataConversionOp< M >

Converts HDF5 data to use desired data type, scaling and encoding (ODIM gain, offset, undetect and nodata values).

Template Parameters

M	- ODIM type

See also: Conversion

Member Function Documentation

◆ processDataSet()

template<class M >

void processDataSet	(	const DataSet< src_t > &	srcSweep,
		DataSet< dst_t > &	dstProduct
	)		const

virtual

SWAP & delete

◆ processH5()

template<class M >

void processH5	(	const Hi5Tree &	src,
		Hi5Tree &	dst
	)		const

virtual

Ensures data to be in standard type and scaling. Makes a converted copy if needed.

Converts src to dst such that dst applies desired gain, offset, undetect and nodata values.

The operator does not need groups sorted by elevation.

Reimplemented from RadarProductOp< M, M >.

◆ processImage()

template<class M >

void processImage	(	const ODIM &	odimSrc,
		const drain::image::ImageFrame &	src,
		const ODIM &	odimDst,
		drain::image::Image &	dst
	)		const

Converts src to dst such that dst applies desired gain, offset, undetect and nodata values.

Sometimes this is applied directly (for alpha channel ops).

◆ setGeometry()

template<class M >

void setGeometry	(	const M &	srcODIM,
		PlainData< dst_t > &	dstData
	)		const

inlinevirtual

Sets automagically the suitable dst parameters.

Derives geometry for the resulting dst from three sources of parameters: the implicit operator parameters this->odim and the two function parameters

Parameters

srcODIM	- metadata of the incoming data
dstODIM	- metadata of the result (sometimes partially set).

Default implementation as an empty function, because some operators like VerticalProfileOp will not use?

Implements RadarProductOp< M, M >.

◆ traverseImageFrame()

template<class M >

void traverseImageFrame	(	const ODIM &	odimSrc,
		const drain::image::ImageFrame &	src,
		const ODIM &	odimDst,
		drain::image::ImageFrame &	dst
	)		const

Checks 'undetect' first because 'undetect' and 'nodata' may be the same code
