- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {

    if(!mouseSwiped) {
        CGContextSetBlendMode(UIGraphicsGetCurrentContext(), kCGBlendModeClear);
        UIGraphicsBeginImageContext(ivBack.frame.size);
        [drawImage.image drawInRect:CGRectMake(0,0, self.ivBack.frame.size.width,self.ivBack.frame.size.height)];
        CGContextSetLineCap(UIGraphicsGetCurrentContext(), kCGLineCapRound);
        CGContextSetLineWidth(UIGraphicsGetCurrentContext(), line);
        CGContextSetStrokeColorWithColor(UIGraphicsGetCurrentContext(), [pickColor CGColor]);
        CGContextMoveToPoint(UIGraphicsGetCurrentContext(), lastPoint.x, lastPoint.y);
        CGContextAddLineToPoint(UIGraphicsGetCurrentContext(), lastPoint.x, lastPoint.y);
        CGContextStrokePath(UIGraphicsGetCurrentContext());
        CGContextFlush(UIGraphicsGetCurrentContext());

 NSData *dataImage=UIImagePNGRepresentation(UIGraphicsGetImageFromCurrentImageContext());
        [dataImage writeToFile:[self SavedImage:(@"1.png")] atomically:YES];
