Class CompositeRed

  extended by org.apache.batik.ext.awt.image.rendered.AbstractRed
      extended by org.apache.batik.ext.awt.image.rendered.CompositeRed
All Implemented Interfaces:
RenderedImage, CachableRed

public class CompositeRed
extends AbstractRed

This is an implementation of an affine operation as a RenderedImage. Right now the implementation makes use of the AffineBufferedImageOp to do the work. Eventually this may move to be more tiled in nature.

Constructor Detail


public CompositeRed(List srcs,
                    CompositeRule rule)
Method Detail


public WritableRaster copyData(WritableRaster wr)


public Raster getTile(int x,
                      int y)
Specified by:
getTile in interface RenderedImage
getTile in class AbstractRed


public void emptyRect(WritableRaster wr)


public void genRect(WritableRaster wr)


public void genRect_OVER(WritableRaster wr)


protected static SampleModel fixSampleModel(CachableRed src,
                                            ColorModel cm,
                                            Rectangle bounds)
This function 'fixes' the source's sample model. right now it just ensures that the sample model isn't much larger than my width.


protected static ColorModel fixColorModel(CachableRed src)
