Subject: GIF and LZW support

I have tried to license GIF support for Envision, but UniSys was very uncooperative; they told me they do not offer licensing for shareware toolkits.

It does not mean that LZW cannot be used with Envision, but LZW code may not be included with the Envision library because the algorithm is patented in Canada and other countries. Note that a license for LZW must obtain from UniSys if their patent applies in your country, when using the LZW algorithm.

There is an excellent GIF freeware library at
<a rel=nofollow target=_blank href="http://www.melander.dk.">http://www.melander.dk.</a> Starting from version 1.03 the
TImageScrollBox component may load graphics supported by
any TGraphic derived class. For example, if Anders Melander's GifImage unit is included in a uses clause, it is possible to load GIF files, but not animated GIF's in the TImageScrollBox component.

Best regards,
