How it layers
Section titled “How it layers”- Loupes always sit above every other annotation, so they magnify arrows, text and everything else under them
- A loupe doesn’t magnify another loupe
- Loupes can be moved and resized, but not rotated
- Small text — Drop a lens on the detail you want people to read
- Clean zoom — Set Distortion and Edge Bend to 0 for a flat magnifier
- Big glass — Turn up Edge Bend and Distortion for a lens that looks like it’s sitting on the screen
