I have fixed most of those now, but there is a third type:<br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">* filters that need the whole image (as in all pixels)<br>
<br>Examples are the autocontrast and small tiles filters.<br></blockquote></div><br>Afair Cyrille has fixed autocontrast to use Histogram so it shouldn't need it anymore.<br><br>As for small tiles you can try return the whole image as neededRect(). But make sure this filter is not available for filter layers, because it can make composition really slow.<br clear="all">
