\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.

conditions under which the code is supplied.
\section1 FreeType 2 (\c freetype) version 2.3.6
\e{The FreeType project is a team of volunteers who develop free, portable

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
\i Renamed: ftgrays.c to qgrayraster.c

decompression. JPEG (pronounced "jay-peg") is a standardized compression
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
src/3rdparty/libjpeg/README.
See \c src/3rdparty/libjpeg/README for license details.
