javax.media.jai.OpImage
   com.sun.media.jai.opimage.TranslateIntOpImage

TranslateIntOpImage
final public class TranslateIntOpImage extends OpImage (Code)
An OpImage to translate an image by in integral number of pixels.

The translation is accomplished by simply shifting the tile grid.




Constructor Summary
public  TranslateIntOpImage(RenderedImage source, Map config, int transX, int transY)
     Construct an TranslateIntOpImage.

Method Summary
public  RastercomputeTile(int tileX, int tileY)
     Override computeTile() simply to invoke getTile().
public  booleancomputesUniqueTiles()
     Returns false as computeTile() invocations return child Rasters of the RenderedImage source and are therefore not unique objects in the global sense.
public  RastergetTile(int tileX, int tileY)
     Get a tile.
public  RectanglemapDestRect(Rectangle destRect, int sourceIndex)
     Returns a conservative estimate of the region of a specified source that is required in order to compute the pixels of a given destination rectangle.
Parameters:
  destRect - the Rectangle in destination coordinates.
Parameters:
  sourceIndex - the index of the source image.
public  RectanglemapSourceRect(Rectangle sourceRect, int sourceIndex)
     Returns a conservative estimate of the destination region that can potentially be affected by the pixels of a rectangle of a given source.
Parameters:
  sourceRect - the Rectangle in source coordinates.
Parameters:
  sourceIndex - the index of the source image.


Constructor Detail
TranslateIntOpImage
public TranslateIntOpImage(RenderedImage source, Map config, int transX, int transY)(Code)
Construct an TranslateIntOpImage.
Parameters:
  source - a RenderedImage.
Parameters:
  config - Configurable attributes of the image includingconfiguration variables indexed byRenderingHints.Keys and image properties indexedby Strings or CaselessStringKeys.This is simply forwarded to the superclass constructor.
Parameters:
  transX - the number of pixels of horizontal translation.
Parameters:
  transY - the number of pixels of vertical translation.




Method Detail
computeTile
public Raster computeTile(int tileX, int tileY)(Code)
Override computeTile() simply to invoke getTile(). Required so that the TileScheduler may invoke computeTile().



computesUniqueTiles
public boolean computesUniqueTiles()(Code)
Returns false as computeTile() invocations return child Rasters of the RenderedImage source and are therefore not unique objects in the global sense.



getTile
public Raster getTile(int tileX, int tileY)(Code)
Get a tile.
Parameters:
  tileX - The X index of the tile.
Parameters:
  tileY - The Y index of the tile.



mapDestRect
public Rectangle mapDestRect(Rectangle destRect, int sourceIndex)(Code)
Returns a conservative estimate of the region of a specified source that is required in order to compute the pixels of a given destination rectangle.
Parameters:
  destRect - the Rectangle in destination coordinates.
Parameters:
  sourceIndex - the index of the source image. a Rectangle indicating the required source region.
throws:
  IllegalArgumentException - if the source index isnegative or greater than that of the last source.
throws:
  IllegalArgumentException - if destRect is null.



mapSourceRect
public Rectangle mapSourceRect(Rectangle sourceRect, int sourceIndex)(Code)
Returns a conservative estimate of the destination region that can potentially be affected by the pixels of a rectangle of a given source.
Parameters:
  sourceRect - the Rectangle in source coordinates.
Parameters:
  sourceIndex - the index of the source image. a Rectangle indicating the potentially affecteddestination region. or null if the region is unknown.
throws:
  IllegalArgumentException - if the source index isnegative or greater than that of the last source.
throws:
  IllegalArgumentException - if sourceRect is null.
