com.lightcrafts.mediax.jai.PlanarImage.YToTileY()
Converts a pixel's Y coordinate into a vertical tile index relative to a given tile grid layout specified by its Y offset and tile height.
If tileHeight < 0, the results of this method are undefined. If tileHeight == 0, an ArithmeticException will be thrown. @throws ArithmeticException If tileHeight == 0.

                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;
                subRect.width = w;
