<div>sorry for that last mail. What i meant to write was:</div>
<div>I have values lying around zero, not having the exact value 0.</div>
<div>So i need to find the pixels that are involved in a zerocrossing.</div>
<div>Reading from the docs of the contourfilter it seems that i here can only set a series of discrete values, and not a interval of some sort to draw the contour.</div>
<div> </div>
<div>So if i am not much mistaken this cannot find zerocrossings, but only show specified values. Correct?</div>
<div> </div>
<div>Thank you<br><br> </div>
