Constructor Detail


public PadRed(CachableRed src,
              Rectangle bounds,
              PadMode padMode,
              RenderingHints hints)
Construct A Rendered Pad operation. If the pad is smaller than the original image size then this devolves to a Crop.

src - The image to pad/crop
bounds - The bounds of the result (same coord system as src).
padMode - The pad mode to use (currently ignored).
hints - The hints to use for drawing 'pad' area.
Method Detail


public WritableRaster copyData(WritableRaster wr)


protected void handleZero(WritableRaster wr)


protected void handleReplicate(WritableRaster wr)


protected void handleWrap(WritableRaster wr)


protected static SampleModel fixSampleModel(CachableRed src,
                                            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.
