如何撤消矩形部分 [英] How to backout section of a rectangle

问题描述

基本上试图绘制一个填充的矩形并删除内部矩形的一部分.例如，从矩形的中心绘制一个100PX x 100PX并删除一个50PX x 50PX的正方形.最终结果看起来像墙上的窗户.谢谢

Basically trying to draw a filled rectangle and remove a part of the inner rectangle. For example drawing a 100PX by 100PX and removing a 50PX by 50PX square from the center of the rectangle. The end result would look like a window in a wall. Thanks

推荐答案

只需在第一个矩形内绘制第二个矩形，并用白色或其他能提供所需外观的颜色填充它即可.

Just draw a second rectangle inside the first and fill it with white, or some other colour that gives the look you want.
