Ruler Units
The default unit is px, and a line is drawn every 50px. If you want to use a different unit instead of the px unit, use it like this:
- 1px (Default)
- zoom: 1
- unit: 50 (every 50px)
- 1cm = 37.7952px
- zoom: 37.7952
- unit: 1 (every 1cm)
- 1in = 96px = 2.54cm
- zoom: 96
- unit: 1 (every 1in)
