yes, it works!<br>Thanks for your fix :-D<br><br>I will commit it<br><br><br>PS: but feDisplacementMap still has some artifacts on the right and bottom edges.

Hi all!<br><br>Atm, feDisplacementmap output depends on zoom factor (see <a href="https://bugs.launchpad.net/inkscape/+bug/182059" target="_blank">here</a>).<br>I had a look at the code to try to fix this, but I need someone to validate the code.<br>



Precise meaning of area, unit transforms, and particulraily of the function &quot;enlarge_area&quot; are not perfectly clear to me.<br><br>The modifs are all in <a href="http://launchpadlibrarian.net/11804938/nr-filter-displacement-map.cpp" target="_blank">nr-filter-displacement-map.cpp.</a><br>



I just changed &quot;scale&quot; with &quot;scalex&quot; and &quot;scaley&quot; defined as:
<p>&nbsp;&nbsp;&nbsp;&nbsp;Matrix trans = units.get_matrix_primitiveunits2pb();<br>
&nbsp;&nbsp;&nbsp;&nbsp;double scalex = scale*trans.expansionX();<br>
&nbsp;&nbsp;&nbsp;&nbsp;double scaley = scale*trans.expansionY();</p>
<p>where apparently appropriate (in the render() and enlarge_area() methods), but I would feel more confortable if someone having a better understanding of the code could check if this is correct or if other changes are needed elsewhere...</p>



Thanks!<br>jfb.<br>
