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.
