Detailed Description

Class which implements simple resampling for the WorldCanvas.

Prerequisite

WCResampleHandler

Etymology

The name "WCSimpleResampleHandler" is a contraction of the terms "WorldCanvas," "Simple," "Resample" and "Handler."

Synopsis

This class implements the interface defined in WCResampleHandler to provide pixel interpolation (resampling) of data pixels to screen pixels. It offers simple nearest, linear and cubic interpolation.

Motivation

The provision of raster images which are smooth in appearance.

Constructor & Destructor Documentation

casa::WCSimpleResampleHandler::WCSimpleResampleHandler ( )

Default constructor (Provides NEAREST)

casa::WCSimpleResampleHandler::WCSimpleResampleHandler ( casacore::Interpolate2D::Method type = casacore::Interpolate2D::NEAREST )

Constructor.

casa::WCSimpleResampleHandler::WCSimpleResampleHandler ( const WCSimpleResampleHandler & other )

virtual

Destructor.

Member Function Documentation

virtual void casa::WCSimpleResampleHandler::operator()	(	casacore::Matrix< casacore::Bool > &	out,
		const casacore::Matrix< casacore::Bool > &	in
	)

virtual

The output array is presized by the caller to the correct size.

It will be filled using information in the input array combined with other resample-specific information. Here again the interface is type expanded rather than templated because C++ doesn't yet handle templated member functions in a non-templated class.
