Fractal mirror guide
Every control
Every control in the panel, top to bottom. Some sliders matter only in some modes; the line says which.
Load and save
They stay at the top while the panel scrolls. Your pictures stay on this device for every lab tool until you press × on a tile; Reset puts the controls back and leaves them.
- Image AButton
- Your picture. Press it to open one from your device, or drop one on the frame; two at once fill A and B. It is kept on this device, never uploaded, and every lab tool that takes a picture opens with it until you press × on its corner.
- SwapButton
- Changes which tile Fractal mirror uses, so a picture you added as B in another tool can be used here. When the other tile is empty, the sample comes back.
- Image BButton
- A second kept picture. Fractal mirror repeats one picture at a time: the tile it is not using is dimmed and says Not used here, and pressing it only says so.
- Save PNGButton
- Saves the picture as fractal-mirror.png.
- CopyButton
- Copies the picture to the clipboard.

A line shows the size of the picture the tool is working on.
