35Qt contains a little code that is not under the <a href="license.html">QPL</a>, the <a href="gpl.html">GPL</a>, or the Qt Commercial
36License Agreement, but rather under specific highly permissive
37licenses from the original authors. This page lists the licenses used
38for that code, names the authors, and links to the points where it is
39used.
40<p> Trolltech gratefully acknowledges these and others contribution to
41Qt. We recommend that all programs that use Qt also acknowledge these
42contributions, and quote all these license statements in an appendix
43to the documentation.

275<p> TrueType font support. These functions allow PPR to generate
276PostScript fonts from Microsoft compatible TrueType font files.
277<p> The functions in this file do most of the work to convert a
278TrueType font to a type 3 PostScript font.
279<p> Most of the material in this file is derived from a program called
280"ttf2ps" which L. S. Ng posted to the usenet news group

304<p> Qt supports GIF reading if it is configured that way during
305installation (see qgif.h). If it is, we are required to state that
306"The Graphics Interchange Format(c) is the Copyright property of
307CompuServe Incorporated. GIF(sm) is a Service Mark property of
308CompuServe Incorporated."
309<p> <b>Warning:</b> If you are in a country that recognizes software patents
310and in which Unisys holds a patent on LZW compression and/or
311decompression and you want to use GIF, Unisys may require you to
312license that technology. Such countries include Canada, Japan,
313the USA, France, Germany, Italy and the UK.
314<p> GIF support may be removed completely in a future version of Qt.
315We recommend using the MNG or PNG format.<ul>
