Constructor Detail

PadRed

public PadRed(CachableRed src,
              java.awt.Rectangle bounds,
              PadMode padMode,
              java.awt.RenderingHints hints)

Construct A Rendered Pad operation. If the pad is smaller than the original image size then this devolves to a Crop.

Parameters:

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

copyData

public java.awt.image.WritableRaster copyData(java.awt.image.WritableRaster wr)

handleZero

protected void handleZero(java.awt.image.WritableRaster wr)

handleReplicate

protected void handleReplicate(java.awt.image.WritableRaster wr)

handleWrap

protected void handleWrap(java.awt.image.WritableRaster wr)

fixSampleModel

protected static java.awt.image.SampleModel fixSampleModel(CachableRed src,
                                                           java.awt.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.
