    \title Third-Party Licenses Used in Qt

    \ingroup licensing

    \brief License information for third-party libraries supplied with Qt.

    Qt includes a number of third-party libraries that are used to provide

    certain features. Unlike the code described in the

    \l{Other Licenses Used in Qt}{code used in Qt} document, these

    libraries are supplied alongside the Qt modules.

    Third Party Software may impose additional restrictions and it is the

    user's responsibility to ensure that they have met the licensing

    requirements of the GPL, LGPL, or Qt Commercial license and the relevant

    license of the Third Party Software they are using.

    Run \c{configure -help} to see any options that may be available for

    controlling the use of these libraries.

    See also the files in \c src/3rdparty/harfbuzz, which are used by

    FreeType.

    Parts of the FreeType projects have been modified and put into Qt

    for use in the painting subsystem. These files are ftraster.h,

    ftraster.c, ftgrays.h and ftgrays.c. The following modifications

    has been made to these files:

    \list

    \i Renamed FT_ and ft_ symbols to QT_FT_ and qt_ft_ to avoid name

    conflicts.

    \i Removed parts of code not relevant when compiled with

    _STANDALONE_ defined.

    \i Changed behavior in ftraster.c to follow X polygon filling

    rules.

    \i Implemented support in ftraster.c for winding / odd even

    polygon fill rules.

    \i Replaced bitmap generation with span generation in ftraster.c

    \i Renamed: ftraster.h to qblackraster_p.h

    \i Renamed: ftraster.c to qblackraster.c

    \i Renamed: ftgrays.h to qgrayraster_p.h

    method for full-color and gray-scale images.  JPEG is intended for compressing

    "real-world" scenes; line drawings, cartoons and other non-realistic images

    are not its strong suit.  JPEG is lossy, meaning that the output image is not

    exactly identical to the input image.} -- quoted from \c
