MlibScaleNearestOpImage
final class MlibScaleNearestOpImage extends MlibScaleOpImage (Code)
An OpImage class that scales an image using nearest-neighbor interpolation.



Constructor Summary
public  MlibScaleNearestOpImage(RenderedImage source, BorderExtender extender, Map config, ImageLayout layout, float xScale, float yScale, float xTrans, float yTrans, Interpolation interp)
     Constructs an MlibScaleNearestOpImage.

Method Summary
protected  voidcomputeRect(Raster[] sources, WritableRaster dest, Rectangle destRect)
     Scale the given rectangle by the specified scale and translation factors.


Constructor Detail
MlibScaleNearestOpImage
public MlibScaleNearestOpImage(RenderedImage source, BorderExtender extender, Map config, ImageLayout layout, float xScale, float yScale, float xTrans, float yTrans, Interpolation interp)(Code)
Constructs an MlibScaleNearestOpImage. The image dimensions are copied from the source image. The tile grid layout, SampleModel, and ColorModel may optionally be specified by an ImageLayout object.
Parameters:
  source - a RenderedImage.
Parameters:
  layout - an ImageLayout optionally containing the tilegrid layout, SampleModel, and ColorModel, or null.
Parameters:
  xScale - the x scaling factor.
Parameters:
  yScale - the y scaling factor.
Parameters:
  xTrans - the x translation factor.
Parameters:
  yTrans - the y translation factor.
Parameters:
  interp - the Nearest interpolation object.




Method Detail
computeRect
protected void computeRect(Raster[] sources, WritableRaster dest, Rectangle destRect)(Code)
Scale the given rectangle by the specified scale and translation factors. The sources are cobbled.
Parameters:
  sources - an array of sources, guarantee to provide allnecessary source data for computing the rectangle.
Parameters:
  dest - a tile that contains the rectangle to be computed.
Parameters:
  destRect - the rectangle within this OpImage to be processed.
