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