The CImage class enables an application to load, save and display a variety of bitmap
types. JPEG, PNG and BMP reading and writing are implemented, plus GIF reading.
There are also facilities for manipulating the image directly.

This code is the result of efforts from many people: I have just modified it, essentially to
make it suitable for MFC usage.

Acknowledgements are due to at least the following.

\begin{itemize}\itemsep=0pt
\item Alejandro Aguilar-Sierra for the original wxImage class;
\item Andrew Davison and Paul Shirley for modifications;
\item Guy Eric Schalnat for the PNG library;
\item members of the Independent JPEG Group for the JPEG library;
\item Phil Katz, Peter Deutsch, Jean-Loup Gailly, Mark Adler for the ZLIB library
used in the PNG code;
\item Microsoft for the DIB utilities;
\item Steven A. Bennett for the GIF decoder.
\end{itemize}

It would be great if people can contribute to the class, such as GIF
writing code, implementations for other formats, bug fixes etc. My address is:

Unarchive the distribution into a suitable directory, and compile each
of the {\tt jpeg, png, zlib, cimage} and {\tt demo} directories using the MS VC++
4.0 project files provided.

To use the library in your application, you will need to link with the
various libraries. For Debug and Release versions, add one of
the following lines to your link setting, prepending a suitable
absolute or relative path to each library specification:

\begin{verbatim}
cimage\Debug\cimage.lib jpeg\Debug\jpeg.lib png\Debug\png.lib zlib\Debug\zlib.lib
cimage\Release\cimage.lib jpeg\Release\jpeg.lib png\Release\png.lib zlib\Release\zlib.lib
\end{verbatim}

Include the file {\tt cimage.h}, and also {\tt imaiter.h} if you wish to use the
CImageIterator class.
