See section below.\n* The default deflate library uses our implementation. We are constantly improving it, but if you are not satisfied with its performance, you can implement a custom class to replace it with another implementation. See also `DeflateDecoder` or `DeflateEncoder`.\n* The detailed specifications are subject to change as it is still under development.\n\n### MSRV\n\n* Undetermined, The latest version is recommended whenever possible.\n\n### Supported features\n\n|feature|supported|\n|-|-|\n|IHDR chunk|✅|\n|PLTE chunk|✅|\n|IDAT chunk|✅|\n|IEND chunk|✅|\n|other chunks|ignored|\n|8bit depth color|✅|\n|16bit depth color|-|\n|Interlace|-|\n|Color space|-|\n|CRC validation|-|\n|checksum|-|\n\n## Example Apps\n\n### /examples/viewer: Image Viewer\n\n* An example application to display PNG files using `embedded-graphics`\n\n```sh\n$ cargo run -p viewer FILE_NAME\n```\n\n## /examples/idatdump: IDAT dumper\n\n* An example application showing the contents of IDAT chunks\n\n```sh\n$ cargo run -p idatdump -- [MODE] [OPTIONS] [--] FILE_NAME\n```\n\n### Modes:\n* `-raw`       Decompress IDAT chunks and dump them as is **(default)**\n* `-filter`    Decompress IDAT chunks to show only filter types\n* `-decoded`   Dumps the final decoding results of the image data\n\n### Options:\n\n* `-hex`    Show in hex **(default)**\n* `-bin`    Show in binary\n* `-b64`    Show in base64\n\n## References\n\n* [Portable Network Graphics (PNG) Specification](https://www.w3.org/TR/png/)\n\n## LICENSE\n\nMIT License\n\n(c) nerry\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fneri%2Fpngss","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fneri%2Fpngss","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fneri%2Fpngss/lists"}
