I made it myself, it’s been a week since I finished it, and I just put it on the website.
The software is 335K, and only the form icons and program icons take up 300K, which is frustrating.

1. The red ruler is the original size, and the blue ruler is three times magnified
2. Press the keyboard up, down, left and right to fine-tune
3. The mouse can drag the length of the ruler!
4. Right-click to see the menu, you can place the ruler or change the length
There is a software Mark Man that I also love~~
It’s pretty good. ,. Supported
