If you are using\na different operating system or architecture such as macOS or Windows; you'll have\nto build and install Para yourself!\n\n#### Install from self-compile\n\n```shell\ncargo +nightly install --git https://github.com/Fuwn/para --branch main\n```\n\nIf you are building and installing yourself, you must have\n[Rust](https://www.rust-lang.org/) installed!\n\n### Usage\n\n```shell\nusage:  para \u003cin\u003e \u003cindex option\u003e \u003cout\u003e\nindex options:\n        gif\n        thumb\n        dump\n        integer(u16)\n```\n\n### Examples\n\n- `$ para ./example.ppm 23 example.png` will output the twenty-fourth frame\n  of `example.ppm` to `example.png`\n- `$ para ./example.ppm thumb example.png` will output the thumbnail of\n  `example.ppm` to `example.png`\n- `$ para ./example.ppm dump example.json` will output the metadata of\n  `example.ppm` to `example.json`\n- `$ para ./example.ppm gif example.gif` will output `example.ppm`\n  to `example.gif`\n\n### Prebuilt Binaries\n\nPrebuilt binaries for the latest release may or may not be found\n[here](https://github.com/Fuwn/para/releases/latest).\n\n## Credits\n\n- [jaames](https://github.com/jaames) for completing PPM reverse-engineering and\n  writing the [original](https://github.com/Flipnote-Collective/ppm-parser) implementation.\n- [bricklife](http://ugomemo.g.hatena.ne.jp/bricklife/20090307/1236391313),\n  [mirai-iro](http://mirai-iro.hatenablog.jp/entry/20090116/ugomemo_ppm),\n  [harimau_tigris](http://ugomemo.g.hatena.ne.jp/harimau_tigris), and other members\n  of the Japanese Flipnote community who started reverse-engineering the PPM format\n  almost as soon as the app was released.\n- Midmad and WDLMaster for identifying the adpcm sound codec used.\n- [steven](http://www.dsibrew.org/wiki/User:Steven) and\n  [yellows8](http://www.dsibrew.org/wiki/User:Yellows8) for the PPM\n  documentation on DSiBrew.\n- [PBSDS](https://github.com/pbsds) for more PPM reverse-engineering, as well as\n  writing [hatenatools](https://github.com/pbsds/Hatenatools)\n\n## License\n\n[MIT License](./LICENSE)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffuwn%2Fpara","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffuwn%2Fpara","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffuwn%2Fpara/lists"}
