To open DjVu files you can use SumatraPDF software for Windows, Cuminas Official DjVu Browser Plug-in, DjVuLibre DjView, WinDjView and MacDjView Desktop Viewers.ĭjVu documents are optimized for storing OCRed (Optical Character Recognized) documents and allow storage of text layer on top of original text image.ĭevelopers can use an open source library distributed as part of DjVuLibre package.

Internet access for restoring dependenciesīuilding from command line on Windows (tested on Windows 10 with Visual Studio 2019 v16.3 installed).DjVu file extension is a file format used to store compressed documents which include images, text, drawings and photographs. NET desktop development, desktop development with C++. Visual Studio 2019 RTM v16.3 with at least following workloads.

LicenseĭjvuNet.DjvuLibre is double licensed under MIT license and GPL v2 or later.ĭjVuLibre used for format support validation is licensed under GPL v2 or later. This project covers ssmall part of the pipline dealing with input of data encoded in DjVu format. Steps in data analysis comprise data retrieval, reading of data and data conversion into format which later can be processed further. NET bindings project DjvuNet.DjvuLibre is double licensed under MIT and GPL v2 licenses.ĭjvuNet is developed as part of larger effort to create scientific information analysis and understanding framework. Modified library used for testing DjvuNet implementation of DjVu format is available here: DjVuLibre for DjvuNet.ĭue to more restrictive licensing conditions of DjVuLibre. In managed assembly - the issue is still open.ĭjVuLibre was modified by creating libdjvulibre build integration with DjvuNet projects and modifying library by expanding some C APIs throughĪddition of memory management functions exports, implementation of Json formatted output from some dump functions and tools (djvudump),Īnd addition of functions bypassing s-expressions formatting used in text retrieval. Perhaps An圜PU target will be available via NuGet packaging or alternatively via embedding of native binaries NET Bindings for majority of C API are available in DjvuNet.DjvuLibre project. Performance tests are based on DjvuNetTest project with some additional benchmarks planned for implementation soon.įull library format handling validation is realized by using DjVuLibre reference library implementation of DjVu format and supporting tools.

It covers project in top down way and providesĪround 85% code coverage using 2 586 test cases with implementation target being more than 90% code coverage.

Test framework is systematically developed and is composed of unit and functional tests. Support for some DjvuLibre masked image formats is not implemented yet. Image segmentation for Mixed Raster Content done in DjvuLibre with ColorPalette histogram calculation will be entirely rewritten as there was significant progress in image segmentation algorithms in the last two decades. JB decoding is implemented but not optimized, encoding is not implemented. ZP arithmetic coder and BZZ encoding/decoding is fully implemented and reached binary compatibility with DjvuLibre. There was very limited optimization work done in this area with some 30 - 40% improvements in performance and identification of several next optimization targets. To be finished but still has couple bugs which need to be fixed. Image data decoding and encoding with Interpolated Dubuc-Deslauriers-Lemire (DDL) (4, 4) Discrete Wavelet Transform is close Project undergoes several architectural and implementations changes, which are done in "dev" branch.ĭjVu file format parser was optimized and refactored what so far resulted in more than 10x speedup. NET Core 3.0.0 or newer on Windows, Linux, macOS. NET Framework 4.7.2 or newer on Windows and. Furthermore, there are some bugs in image decoder that leave some of images distorted making them useless. There are several known bugs which need to be fixed and missing features which need to be implemented firstīefore library could be treated as production ready or fully functional. Current StatusĭjvuNet library is not ready for production use. Therefore, use it at your own risk and do not blame us for any of your problems. There are known bugs but it should work on large number of djvuįiles (obviously it's still only a subset of all DjVu files which can be found out in the wild). Project was started several years agoīy Telavian and after remaining inactive for some time currently is continued at new The so called "Secure DjVu" format is not supported as this specification was never published. Library supports Djvu format specification version 3 up to the minor version 26 (v3.26).

DjvuNet Library CI status of master branch WindowsĭjvuNet is an open source library designed to process and create documents encoded with DjVu format.
