The background of the image is always either 0 or -1 and what I want to do is transform the image so that any pixel that is not the background colour should get the value of 255.
<br><br>I am pretty sure there will be something in vtk that allows me to do this. I was wondering if someone could point me to the correct filter.<br><br>Thanks a lot.<br clear="all"><br>Cheers,<br><span class="sg"><br>
