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

ae.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-leftcorner of the new Raster @param childMinY the Y coordinate of the upper-leftcorner 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

                int tx = x + relx;
                int tw = Math.min(w-relx, TILE_SIZE);


                Raster srcRaster = paintCtxt.getRaster(tx, ty, tw, th);
                if ((srcRaster.getMinX() != 0) || (srcRaster.getMinY() != 0)) {
                    srcRaster = srcRaster.createTranslatedChild(0, 0);
                }
                if (lastRas != srcRaster) {
                    lastRas = srcRaster;
                    context.lastRaster = new WeakReference(lastRas);
                    // REMIND: This will fail for a non-Writable raster!
