希望集成一键将图像转化为矩形填充图层的功能
<img width="238" alt="image" src="https://user-images.githubusercontent.com/107759063/174440372-0fd84117-d7e2-4a22-ba6b-ba8dd1bea363.png">

Request:
The image layer cannot be scaled adaptively. At present, only frequent steps can be converted into rectangular filling mode.
需求：
图像图层下不能自适应等比缩放，目前仅能频繁步骤转化为矩形填充模式
