<h2>Detailed Description</h2>
<p><dl class="see" compact><dt><b>See also:</b></dt><dd> ThumbCreator
</dd></dl> </p>
<p>
This is an extension of ThumbCreator that allows creating a thumbnail sequence for
a file. If your thumbnail plugin can create a thumbnail sequence, you should base it
on ThumbSequenceCreator instead of ThumbCreator, and should use sequenceIndex()
to decide what thumbnail you generate.
</p>
<p>
You also need to set the following key in the thumbcreator .desktop file
<pre class="fragment">
HandleSequences=true;
</pre>
</p>

<div class="memdoc"><p>If this thumb-creator can create a sequence of thumbnails,
it should use this to decide what sequence item to use.
</p>
<p>
If the value is zero, the standard thumbnail should be created.
</p>
<p>
This can be used for example to create thumbnails for different
timeframes in videos(For example 0m, 10m, 20m, ...).
</p>
<p>
If your thumb-creator supports a high granularity, like a video,
you can respect the sub-integer precision coming from the float.
Else, just round the index to an integer.
</p>
<p>
If the end of your sequence is reached, the sequence should start
from the beginning, or continue in some other way.
