    - `qrm` - Level M (Medium) 15% of data bytes can be restored.
    - `qrq` - Level Q (Quartile) 25% of data bytes can be restored.
    - `qrh` - Level H (High) 30% of data bytes can be restored.
- `w` - Width of image. Overrides `sf` or `sx`.
- `h` - Height of image. Overrides `sf` or `sy`.
- `sf` - Scale factor. Default 4.
- `sx` - Horizontal scale factor. Overrides `sf`.
- `sy` - Vertical scale factor. Overrides `sf`.
- `p` - Padding. Default is 0.
- `pv` - Top and bottom padding. Default is value of `p``.
- `ph` - Left and right padding. Default is value of `p`.
- `pt` - Top padding. Default is value of `pv`.
- `pl` - Left padding. Default is value of `ph`.
- `pr` - Right padding. Default is value of `ph`.
- `pb` - Bottom padding. Default is value of `pv`.
- `fc` - Foreground color in `#RRGGBB` format.
- `bc` - Background color in `#RRGGBB` format.
- `md` - Module density. A number between 0 and 1. Default is 1.
