template<class T>
class casacore::RebinImage< T >

Rebin an image

Intended use:

Public interface

Review Status

Test programs:
tRebinImage

Prerequisite

Synopsis

Class RebinImage can be used to rebin (data averaged over bin) an image by integer amounts per axis.

Example

IPosition factors(2,2,2);
PagedImage<Float> imageIn(String("myImage")):
RebinLattice<Float> rb(imageIn, factors);
IPosition shapeOut = rb.shape();
TiledShape tShapeOut(shapeOut);
TempImage<Float> imageOut(tShapeOut, rb.coordinates());

Motivation

Users like to rebin images...

template<class T >
casacore::RebinImage< T >::RebinImage ( const ImageInterface< T > &  ,
const IPosition factors 
)

Constructor.

The bin factors don't have to be integral. Anything left over at the end is treated as a full bin.

◆ RebinImage() [3/3]

template<class T >
casacore::RebinImage< T >::RebinImage ( const RebinImage< T > &  other)
