Examples of javax.media.jai.PlanarImage.XToTileX()

javax.media.jai.PlanarImage.XToTileX()
Converts a pixel's X coordinate into a horizontal tile index relative to a given tile grid layout specified by its X offset and tile width.
If tileWidth < 0, the results of this method are undefined. If tileWidth == 0, an ArithmeticException will be thrown. @throws ArithmeticException If tileWidth == 0.

                pt[0] = x1;
                pt[1] = y1;
                mapPoint(pt, sMinX, sMinY, sMaxX, sMaxY, type, false);


                // Determine the source tile involved
                int tx = src.XToTileX(pt[0]);
                int ty = src.YToTileY(pt[1]);
                sources[0] = src.getTile(tx, ty);


                subRect.x = x1;
                subRect.y = y1;
