/**
 * rasterize the mask clipped with the Rectangle scaled back to full size with an offset onto a BufferedImage
 */
public int[] getRasterDataMask(int x,int y,int w,int h,  int offsetX, int offsetY, double scalingFactor) {
	Rectangle rect=new Rectangle(x,y,w,h);
    //BufferedImage bi = this.rasterize(rect, offsetX, offsetY, scalingFactor);
