Constructor & Destructor Documentation

casa::ImageRegridder::ImageRegridder

(

)

Top level interface which regrids an image to a specified coordinate system.

Etymology

Regrids image.

Synopsis

High level interface for regridding an image. Note that in the case of a complex-valued image, the image is first divided into its composite real and imaginary parts, and these parts are regridded independently. The resulting regridded images are combined to form the final regridded complex-valued image.

casa::ImageRegridder::ImageRegridder	(	const SPCIIF	image,
		const Record *const	regionRec,
		const String &	maskInp,
		const String &	outname,
		Bool	overwrite,
		const CoordinateSystem &	csysTo,
		const IPosition &	axes,
		const IPosition &	shape
	)

if outname is empty, no image will be written if overwrite is True, if image already exists it will be removed if overwrite is False, if image already exists exception will be thrown

casa::ImageRegridder::ImageRegridder	(	const SPCIIF	image,
		const String &	outname,
		const SPCIIF	templateIm,
		const IPosition &	axes = IPosition(),
		const Record *const	regionRec = 0,
		const String &	maskInp = "",
		Bool	overwrite = False,
		const IPosition &	shape = IPosition()
	)

FIXME Add support to allow image and templateIm to be of different data types.
