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.

Member Function Documentation

virtual void casa::WCSimpleResampleHandler::operator()	(	Matrix< Bool > &	out,
		const Matrix< Bool > &	in,
		const Vector< Float > &	pixblc,
		const Vector< Float > &	pixtrc,
		const Bool	blank = `False`
	)			`[virtual]`

Implements casa::WCResampleHandler.

virtual void casa::WCSimpleResampleHandler::operator()	(	Matrix< Float > &	out,
		Matrix< Bool > &	outMask,
		const Matrix< Float > &	in,
		const Matrix< Bool > &	inMask,
		const Vector< Float > &	inblc,
		const Vector< Float > &	intrc,
		const Float	blank = `0.0`
	)			`[virtual]`

Implements casa::WCResampleHandler.

virtual void casa::WCSimpleResampleHandler::operator()	(	Matrix< Float > &	out,
		const Matrix< Float > &	in,
		const Vector< Float > &	pixblc,
		const Vector< Float > &	pixtrc,
		const Float	blank = `0.0`
	)			`[virtual]`

This function resamples the input matrix to the output.

pixblc is the location relative to the input matrix of the bottom-left pixel of the output (sim. for pixtrc); blank is the output value where none of the input data is useful. The output matrix must be presized to the required size.

Implements casa::WCResampleHandler.

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

Implements casa::WCResampleHandler.

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

Assignment operator (copy semantics).

Reimplemented from casa::WCResampleHandler.

void casa::WCSimpleResampleHandler::setInterpolationType ( Interpolate2D::Method type )

Reset interpolation method.
