PEF Viewer is a free app for braille production facilities working with PEF-files. You can use this app to open PEF-files from e-mail attachments, cloud services and so on.The Portable Embosser Format (PEF) is an award winning data format for representing braille books, accurately and unambiguously; regardless of language, location, embosser settings, braille code and computer environment. It can be used for braille embossing and archiving anywhere in the world, no matter where nor how it was produced.PEF brings a number of things to braille production:* Metadata. A PEF file provides information about its contents.* A braille publishing standard. Since the PEF file format is defined in a publicly available standard, there is never any doubt about how to interpret or use the contents of a PEF file.* A proper file format for braille. Having a proper file format means, among other things, that file integrity can be tested to detect errors.* World wide file sharing. Because PEF is specified and the braille representation unambiguous, it can be shared with anyone in the world. For example, braille music is very expensive to produce, but the braille code used in musical notation is the same all over the world. With PEF, this material can be shared in digital form with anyone.* Archive safety. Because PEF is specified and the braille representation unambiguous, PEF documents can be safely archived for the future.* Economy. Publishing and republishing of braille can be achieved quickly and easily because files can be shared across the world, without worrying about embosser settings. Users can emboss on demand and providers can share resources and reduce costs.For even more information about PEF: see http://pef-format.orgDue to very limited resources for this project, this app has not been tested for accessibility. Thank you for your understanding.
