<p>Hello,</p>
<p>I noticed some bugs about dealing with TIFF images (see
<a class="moz-txt-link-freetext" href="https://bugs.documentfoundation.org/show_bug.cgi?id=126152">https://bugs.documentfoundation.org/show_bug.cgi?id=126152</a> for the
meta).</p>
<p>According to <a class="moz-txt-link-freetext" href="https://en.wikipedia.org/wiki/TIFF">https://en.wikipedia.org/wiki/TIFF</a>, TIFF is quite
complex, I quote:</p>
<p>"TIFF is a complex format, defining many tags of which typically
only a few are used in each file. This led to implementations
supporting very varying subsets of the format, a situation that
gave rise to the joke that TIFF stands for <i>Thousands of
Incompatible File Formats</i>.".</p>
<p>So in <a class="moz-txt-link-freetext" href="https://gerrit.libreoffice.org/c/core/+/133108">https://gerrit.libreoffice.org/c/core/+/133108</a>, I wondered
if we could use Libtiff. Of course as<span id="hovercardTarget"

indicated</span></span></span> it'll need lots of work.
However Mike pointed out Luboš' commit about Webp to take example</p>
<p><a class="moz-txt-link-freetext" href="https://cgit.freedesktop.org/libreoffice/core/commit/?id=60eaa424c5e213f31227008e1ed66a646491a360">https://cgit.freedesktop.org/libreoffice/core/commit/?id=60eaa424c5e213f31227008e1ed66a646491a360</a>
("support for the WebP image format (<a
href="https://bugs.documentfoundation.org/show_bug.cgi?id=114532">tdf#114532</a>)")
which can be a start.<br>
</p>
<p>But before this, is libtiff license compatible?</p>
<p>I mean, I retrieved source code of libtiff and m4/acinclude.m4
indicates (from line 192):</p>

<p>If I remember well, GPL isn't sufficient, we also need LGPL,
don't we?</p>

<p>PS : it's just a question for devs who would be interested in
doing the porting, I wouldn't be able to do this myself.<br>
