Description: Another free C++ image processing and conversion library
Platform: Windows / Linux
License: Freeware
Release: 5.99c
Last update: 17 Oct 2004

Overview
CxImage is a C++ class that can load, save, display, transform images in a very simple and fast way.

CxImage is open source and licensed under the zlib license. In a nutshell, this means that you can use the code however you wish, as long as you don't claim it as your own.

With more than 200 functions, and with comprehensive working demos, CxImage offers all the tools to build simple image processing applications on a fast learning curve. Supported file formats are: BMP, GIF, ICO, CUR, JBG, JPG, JPC, JP2, PCX, PGX, PNG, PNM, RAS, TGA, TIF, WBMP, WMF.

Cximage is highly portable and has been tested with Visual C++ 6 / 7, C++ Builder 3 / 6 on Windows, and with gcc 3.3.2 on Linux. It should compile without problems on C++ compilers that support exception handling. The library can be linked statically, or through a DLL or an activex component.
