Colorverse

Color vision convertor / simluator

Based on Machado, Oliveira & Fernandes (2009) model. Customized with dynamic level parameter introduced and nonlinear easing of the level.

Usage

Executable

Executables on multiple platforms are found in Releases. Just run it without any installation.

$ # usage
$ ./colorverse -c ${color vision} -l ${level} -o ${output file path} ${input file path}

$ # for example
$ ./colorverse -c protanomaly -l 0.75 -o out.png in.png

$ # help
$ ./colorverse --help

Rust and cargo

Configure:

$ cargo add colorverse

Use:

use colorverse::convert;
use colorverse::core::color_vision::color_vision_type::ColorVisionType;

let color_vision_type = ColorVisionType::Protanomaly;
let level = 0.5;
let input_file_path = "tests/fixtures/input.png";
let output_file_path = format!("output-{}-{}.png", color_vision, level * 100.0);

convert(input_file_path, &color_vision, level)
    .unwrap()
    .save_as(output_file_path.as_str());

use colorverse::convert;
use colorverse::core::color_vision::color_vision_type::ColorVisionType;

let mut color_vision_type_iterator = ColorVisionTypeIterator::new(&ColorVisionType::Trichromacy);
while let Some(color_vision_type) = color_vision_type_iterator.next() {
    for level in [0.5, 1.0] {
        match convert("tests/fixtures/input.png", &color_vision_type, level) {
            Ok(x) => {
                let output_file_path = format!("output-{}-{}.png", &color_vision_type, level * 100.0);
                x.save_as(output_file_path.as_str());
            }
            Err(err) => eprintln!("{}", err),
        }
    }
}
