virtual void	setup (IPosition fixedPos)
	This method does setup stuff that is common to all elements of an axis-bound display data element.
virtual IPosition	dataShape ()
	This method should be defined in derived classes to simply return the shape of the data object, eg.
virtual uInt	dataDrawSelf (WorldCanvas *wCanvas, const Vector< Double > &blc, const Vector< Double > &trc, const IPosition &start, const IPosition &sliceShape, const IPosition &stride, const Bool usePixelEdges=False)
	This method should be defined in derived classes to actually draw the data contained in datMatrix, however it likes, starting at the point blc, on *wCanvas.
virtual Bool	dataGetSlice (Matrix< Float > &data, Matrix< Bool > &mask, const IPosition &start, const IPosition &sliceShape, const IPosition &stride)

Member Function Documentation

virtual uInt casa::ScrollingRasterDM::dataDrawSelf	(	WorldCanvas *	wCanvas,
		const Vector< Double > &	blc,
		const Vector< Double > &	trc,
		const IPosition &	start,
		const IPosition &	sliceShape,
		const IPosition &	stride,
		const Bool	usePixelEdges = False
	)		[protected, virtual]

This method should be defined in derived classes to actually draw the data contained in datMatrix, however it likes, starting at the point blc, on *wCanvas.

It must return a uInt which indicates the drawListNumber it allocated for this drawing. If usePixelEdges is True, then the given blc and trc correspond to the world blc and trc of the first and last pixels in the given data, otherwise they correspond to the world centres of the blc and trc pixels.

Implements casa::PrincipalAxesDM.

virtual Bool casa::ScrollingRasterDM::dataGetSlice	(	Matrix< Float > &	data,
		Matrix< Bool > &	mask,
		const IPosition &	start,
		const IPosition &	sliceShape,
		const IPosition &	stride
	)		[protected, virtual]

virtual IPosition casa::ScrollingRasterDM::dataShape

(

)

[protected, virtual]

This method should be defined in derived classes to simply return the shape of the data object, eg.

Array.shape() or Image.shape(), etc.

Implements casa::PrincipalAxesDM.

virtual void casa::ScrollingRasterDM::setup

(

IPosition

fixedPos

)

[protected, virtual]

This method does setup stuff that is common to all elements of an axis-bound display data element.

Reimplemented from casa::PrincipalAxesDM.
