    -(IBAction)cutItem:(id)sender
    {
        hasBeenDragged = NO;
        NSImage *_sourceImage = [self image];
        float width = selectedArea.size.width;
        float height = selectedArea.size.height;
        float centerX = ([self frame].size.width/2)-width/2;
        float centerY = ([self frame].size.height/2)-height/2;
        [_sourceImage lockFocus];
        [[NSColor blackColor] set];
        NSRectFill(NSMakeRect(centerX, centerY, selectedArea.size.width, selectedArea.size.height));
        [_sourceImage unlockFocus];
        [self setImage:_sourceImage];
