Usage

From source file:ClippedDragImage.java

private Rectangle getAffectedArea(int oldx, int oldy, int newx, int newy, int width, int height) {
    int x = Math.min(oldx, newx);
    int y = Math.min(oldy, newy);
    int w = (Math.max(oldx, newx) + width) - x;
    int h = (Math.max(oldy, newy) + height) - y;
    return new Rectangle(x, y, w, h);
