The core Qt Gui library by default supports reading and writing image files of the most common file formats: PNG, JPEG, BMP, GIF and a few more, see the Reading and Writing Image Files section in QImage class reference. 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. This package contains actual libraries to be used by apps.
