Based on [Machado, Oliveira & Fernandes (2009)](https://www.inf.ufrgs.br/~oliveira/pubs_files/CVD_Simulation/CVD_Simulation.html) model.
Customized with dynamic simulation level parameter introduced and nonlinear easing of the level.

## Usage

### Executable

Executables on multiple platforms are found in [Releases](https://github.com/accessible-colors/colorverse/releases/latest). Just run it without any installation.

```console
$ # usage
$ ./colorverse simulate -c ${color vision} -l ${simulation level} -o ${output file path} ${input file path}
$ ./colorverse daltonize -c ${color vision} -l ${simulation level} -s {daltonization strength} -o ${output file path} ${input file path}

$ # for example
$ ./colorverse simulate -c protanomaly -l 0.75 -o simulate-out.png in.png
$ ./colorverse daltonize -c deuteranomaly -l 1.0 -s 1.0 -o daltonize-out.png in.png

$ # help
$ ./colorverse --help
$ ./colorverse simulate --help
$ ./colorverse daltonize --help
```

### Rust and `cargo`

See [docs/DEVELOPMENT.md](docs/DEVELOPMENT.md).
