Class RgbPaperType2D

      extended by uk.ac.starlink.ttools.plot2.paper.RgbPaperType2D
All Implemented Interfaces:
PaperType, PaperType2D
Direct Known Subclasses:
CompositePaperType2D, OverPaperType2D

public abstract class RgbPaperType2D
extends RgbPaperType
implements PaperType2D

Abstract RgbPaperType subclass for 2-dimensional plots.

Note that the default RgbPaperType.placeDecal(uk.ac.starlink.ttools.plot2.paper.Paper, uk.ac.starlink.ttools.plot2.Decal) implementation paints directly to the RGB Image's graphics context. so that in the presence of decals, using the it is not OK to wait until flush time and then render everything to the image, unless you suitably override placeDecal as well.
