Detailed Description

Reduce the pixel dimensions of an image.

Reduce the pixel dimensions of an image. Has the functionality to reduce only a sub area in input image to output

Author: 1995-11-06 Jeff Anderson

History:: 2011-04-15 Sharmila Prasad - Ported the class from "reduce" app to base object class.

History:: 2011-05-10 Sharmila Prasad - Fixed error while setting input bands and moved static members to data members in Average class.

History:: 2011-05-11 Sharmila Prasad - Use Portal instead of LineMgr to read Line & added API setInputBoundary to reduce subarea of an image

History:: 2011-08-19 Jeannie Backer - Modified unitTest to use $temporary variable instead of /tmp directory.

History:: 2012-02-01 Sharmila Prasad - Remove unused band data member Fixes #00681

History:: 2013-01-16 Tracie Sucharski - Fixed bug caused by a round off error when calculating scales when output line and sample are entered. This resulted in output bands beyond band 1 being NULL in the output cube. This only happened with certain values of output lines and scales. Also, fixed the the swapping of output samples and lines in the Results group in the print.prt file. Fixes #1385.

Constructor & Destructor Documentation

◆ Reduce()

Isis::Reduce::Reduce	(	Isis::Cube *	pInCube,
		const double	sampleScale,
		const double	lineScale
	)

Constructor.

Reduce Constructor.

Author: Sharmila Prasad (4/26/2011)

Parameters

pInCube	- Input cube
psBands	- Bands list
sampleScale	- Sample scale
lineScale	- Line scale

History:: 2013-01-16 Tracie Sucharski - Use rounding instead of ceil function to prevent errors that were caused by round off. The reduce application would get ons, onl from the user, calculate scale and pass the scale in to this class, which would calculate ons, onl, which could be different from the user entered values.

◆ ~Reduce()

Isis::Reduce::~Reduce ( )

Destructor.

Author: Sharmila Prasad (5/11/2011)

Member Function Documentation

◆ setInputBoundary()

void Isis::Reduce::setInputBoundary	(	int	startSample,
		int	endSample,
		int	startLine,
		int	endLine
	)

Parameters to input image sub area.

Parameters to input image sub area to be reduced.

Author: Sharmila Prasad (5/11/2011)

Parameters

startSample	- input image start sample
endSample	- input image end sample
startLine	- input image start line
endLine	- input image end line

◆ UpdateOutputLabel()

Isis::PvlGroup Isis::Reduce::UpdateOutputLabel ( Isis::Cube * pOutCube )

Create label for the reduced output image.

Update the Mapping, Instrument, and AlphaCube groups in the output cube label.

Parameters

pOutCube	- Resulting reduced output cube
pResultsGrp	- This is the Results group that will go into the application log file. This group must be created by the calling application. Information will be added to it if the Mapping or Instrument groups are deleted from the output image label
