+\title Qt Image Formats
+\page qtimageformats-index.html
+\brief Qt Image Formats module provides support for extra image file formats
+
+The core Qt Gui library by default supports reading and writing image
+files of the most common file formats: \c PNG, \c JPEG, \c BMP, \c GIF
+and a few more, ref. \l {QImage#Reading and Writing Image Files}{Reading
+and Writing Image Files}. The Qt Image Formats add-on module provides
+optional support for other image file formats.
+
+The file format support is provided transparently, through plugins for
+Qt's image I/O system. As such, this module provides no API of its
+own. Instead, the functionality is accessed in the same way as other
+image I/O in Qt: through QImage::load() and QImage::save(). Or, for
+more detailed control, through QImageReader and QImageWriter.
+
+\section1 The Image I/O Plugins
+
+The actual coding and decoding of the file format is done by a codec
+library. The codec can be Qt or third party code. In case of a third
+party codec, the build process will look for it among the system
+libraries. If not found, it may fall back on using a bundled copy (in
+\c src/3rdparty).
+
+\table
+\header \li Format \li Description                      \li Support      \li 3rd party codec
+\row    \li MNG    \li Multiple-image Network Graphics  \li Read/write   \li Yes (bundled)
+\row    \li TGA    \li Truevision Graphics Adapter      \li Read/write   \li No
+\row    \li TIFF   \li Tagged Image File Format         \li Read/write   \li Yes (bundled)
+\row    \li WBMP   \li Wireless Bitmap                  \li Read/write   \li No
+\endtable
+
+\section2 Security considerations
+
+Since these file formats are more rarely used, the codecs may be less
+thoroughly debugged against potential security holes. As always, care
+should be taken when creating applications that may be used to decode
+uncontrolled data files.
