omeis.providers.re.codomain.ContrastStretchingContext

public class ContrastStretchingContext
extends CodomainMapContext

Two points pStart and pEnd define the context of this transformation. We determine the equations of 3 lines (segments to be correct). The first one is a line between the point with coordinates (intervalStart, intervalStart) and (xStart, yStart). The second one between (xStart, yStart) and (xEnd, yEnd). The third one between (xEnd, yEnd) and (intervalEnd, intervalEnd).
