Sets up the transform using three points.

Note:

that the third point is assumed to be on the same row as the first point.

Sets up the transform using three points.

Coord RCol2Coord::transform

)

const

transforms a rowcol stored in a coord. The row is stored in the x-component, and the col is stored in the y-component.

BinID RCol2Coord::transformBack	(	const Coord &	,
		const StepInterval< int > *	inlrg = 0,
		const StepInterval< int > *	crlrg = 0
	)			const

Transforms Coord to RowCol. If the ranges are given, they are only used for snapping: the actual range is not used

Coord RCol2Coord::transformBackNoSnap

(

const Coord &

)

const

transforms back, but does not snap. The row is stored in the x-component, and the col is stored in the y-component.
