PFF is zoomify's single-file zoomable image format.\n\nThe pff file format is proprietary, and [I reversed-engineered it](https://github.com/lovasoa/pff-extract/wiki/Zoomify-PFF-file-format-documentation) using only a few sample files. This program is based on this reverse-engineering work, and thus might not work on every pff file. If it doesn't work for you, please [open a bug](https://github.com/lovasoa/pff-extract/issues/new).\n\n## Installation\n\nWe distribute linux and MacOS binaries on our [release page](https://github.com/lovasoa/pff-extract/releases).\nIf you are on windows, you can use the linux (ubuntu) binaries with [WSL](https://docs.microsoft.com/en-us/windows/wsl/install-win10).\n\n## Usage\n```\npff-extract input.pff [output.jpg]\n```\n\n## Compilation\n```\ngcc -o pff-extract pff-extract.c -lturbojpeg\n```\n\n### Dependencies\n * [libjpeg-turbo](http://www.libjpeg-turbo.org/) v2.0+ to decompress the tiles\n   and to compress the resulting image.\n   In ubuntu 20.04+, it can be installed with `sudo apt install libturbojpeg0-dev`.\n   On fedora: `sudo dnf install turbojpeg-devel`.\n\n### Correctness\n\nThis program should handle all files safely, even malformed ones, \nand display a clear error message when it fails to process a file.\nVersion 0.7 was fuzzed for multiple hours on 12 instances of [AFL](https://github.com/google/AFL),\nwithout any crash. The program should be safe from memory errors.\nHowever, this is a free software that comes without any warranty of any kind.\nIf you find an error, you can [report it](https://github.com/lovasoa/pff-extract/issues/new).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flovasoa%2Fpff-extract","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flovasoa%2Fpff-extract","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flovasoa%2Fpff-extract/lists"}
