IM is a toolkit for Digital Imaging. IM is based on 4 concepts: Image Representation, Storage, Processing and Capture. Image Visualization is a task that it is left for a graphics library.
It provides support for image capture, several image file formats and many image processing operations. The most popular file formats are supported: TIFF, BMP, PNG, JPEG, GIF and AVI.
Image representation includes scientific data types (like IEEE floating point data) and attributes (or metadata like GeoTIFF and Exif tags). Animation, video and volumes are supported as image sequences, but there is no digital audio support.
The main goal of the library is to provide a simple API and abstraction of images for scientific applications.
The toolkit API is written in C. The core library source code is implemented in C++ and it is very portable, it can be compiled in Windows and UNIX with no modifications. New image processing operations can be implemented in C or in C++.
IM is free software, can be used for public and commercial applications.
IM has been used in Tecgraf for many theses and dissertations. Check the Publications in Tecgraf's web site http://www.tecgraf.puc-rio.br/.
The library is available for several compilers:
The library is available for several operating systems:
The official support mechanism is by e-mail, using im@tecgraf.puc-rio.br. Before sending your message:
After all of the above have been checked, report the problem, including in your message: function, element, format, platform, and compiler.
We host the IM support features at SourceForge: http://sourceforge.net/projects/imtoolkit/. It provides us Mailing List, SVN Repository and Downloads.
The discussion list is available at:

If you want us to develop a specific feature for the toolkit, Tecgraf is available for partnerships and cooperation.
Lua documentation and resources can be found at http://www.lua.org/.
This work was developed at Tecgraf by means of the partnership with PETROBRAS/CENPES.

We also thank the developers of the third party libraries:
The IM toolkit distribution includes the some third party libraries that are not developed by Tecgraf. Their license are also free and have the same freedom as the Tecgraf Library License. You can read the respective licenses in the files: zlib.txt, libpng.txt, libjpeg.txt, libtiff.txt, libjasper.txt, liblzf.txt, libexif.txt.
Thanks for the SourceForge for hosting the support features. Thanks for the LuaForge team for previously hosting the support features for many years.
