ExactImage

In the mid-2000s we were wondering about the ridiculous amounts of CPU cycles ImageMagick spent on certain image processing tasks. After the first code review it became clear that imagemagick was coded for anything but speed. We prototyped the needed code in C++, just for speed, and achieved processing times about 1/20th of what ImageMagick consumed. In the library we also will experiment and explore several new algorithms, e.g. for de-screening, data-dependant triangulation scaling, lossless JPEG transforms and others as we see need. You are very much welcome to contribute thrilling state-of-the-art algorithms. The included codecs take C++ STL std::istreams and std::ostreams allowing library users to implement their own data sources and destinations, such as in memory Locations or network transfers. It is intended to become a Modern, generic (template) based C++ library, as time permits. - Hopefully a viable alternative to ImageMagick. Since the 0.8 release series comes with support for multiple images per file, e.g. in the TIFF codec and econvert command line front-end. Since the 0.7 release series ExactImage comes with even more image codecs, and support to completely synthesize, that is Create images from scratch and work with vector paths thru the external API. Since the 0.6 release series ExactImage comes with a completely rewritten PDF codec, which is not only capable of dumping image data into a PDF container, but offers complete support for arbitrary vector data, vector font writing support as well as multi-page documents. Based on the new PDF codec a new command line front-end named "hocr2pdf" is included which allows creating searchable PDFs out of hOCR annotated HTML as obtained from some OCR engines.
