Examples of java.awt.image.Raster.createTranslatedChild()

java.awt.image.Raster.createTranslatedChild()
Create a Raster with the same size, SampleModel and DataBuffer as this one, but with a different location. The new Raster will possess a reference to the current Raster, accessible through its getParent() method. @param childMinX the X coordinate of the upper-left corner of the new Raster @param childMinY the Y coordinate of the upper-left corner of the new Raster @return a new Raster with the same size, SampleModel, and DataBuffer as this Raster, but with the specified location. @throws RasterFormatException if computing eitherchildMinX + this.getWidth() or childMinY + this.getHeight() results in integer overflow

      return null;


  return tile.createTranslatedChild(tileXToX(tileX), tileYToY(tileY));
