Method Details

copyData

public WritableRaster copyData(WritableRaster wr)

Specified by:

copyData in interface RenderedImage

getTile

public Raster getTile(int x,
 int y)

Specified by:

getTile in interface RenderedImage

Overrides:

getTile in class AbstractRed

genTile

public Raster genTile(int x,
 int y)

Specified by:

genTile in interface TileGenerator

fillRasterFrom

public WritableRaster fillRasterFrom(WritableRaster wr,
 RenderedImage src)

fillOutRaster

protected void fillOutRaster(WritableRaster wr)

fillOutRaster_INT_PACK

protected void fillOutRaster_INT_PACK(WritableRaster wr)

fillOutRaster_FALLBACK

protected void fillOutRaster_FALLBACK(WritableRaster wr)

fixSampleModel

protected static SampleModel fixSampleModel(RenderedImage src,
 int stepX,
 int stepY,
 int width,
 int height)

This function 'fixes' the source's sample model. right now it just ensures that the sample model isn't much larger than my width.
