A fast, modern and generic image processing library...

A fast, modern and generic image processing library

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.

Since the 0.5 release series ExactImage comes with the first open-source, GPL, barcode recognition support ever, an additional, high-performance image pixel iteration, code generation facility was added, providing an additional speed boost over the former, pre-0.5 Image iteration implementation. All algorithms converted to the new iterator can profit from up to 10x acceleration. Support for writing non-RGB BMP files, as well as EPS, PS and PDF files and rendering some SVG files was added. Additionally, language bindings for PHP, Python and Lua can be generated by the build system (pre-0.5 only a Perl bindings was generated).

Since the 0.4 release series ExactImage supports drawing vector graphic thru the Anti Grain Geometry rendering engine as well as image segmentation and fuzzy image pattern matching.

Since the 0.3 release series ExactImage supports per-codec acceleration of rotation, flipping, scaling and color-space conversion (for JPEG, ala jpegtran) as well as on-demand decoding.

Since the 0.2 release series ExactImage comes with a stable, simple and easy to use external API including SWIG support, thus allowing the use out of any SWIG supported scripting language, such as Perl, PHP, Python, Ruby or LUA.
