<DIV><FONT face=Arial size=2>Hi everybody!</FONT></DIV>
<DIV><FONT face=Arial size=2> I'm trying to superimpose two
images, with the original in the background and the other being the result of a
segmentation done with ITK on the original one.</FONT></DIV>
<DIV><FONT face=Arial size=2> As it is a segmentation, there's
lots of black pixels, that will hide the image behind it (the original one). I'm
trying to do the whole thing by defining an actor out of each image and adding
them to the same renderer, and then setting the color and opacity of the result
image(the actor) so that i'm still able to see the original one behind it, but
without any success. </FONT></DIV>
<DIV><FONT face=Arial size=2> Is there any way of NOT SHOWING
the completely dark pixels i.e. setting the opacity of color (0,0,0) to 0? That
would solve the problem, wouldn't it?</FONT></DIV>
<DIV><FONT face=Arial size=2> Any other ways of getting around
this situation is also welcome.</FONT></DIV>

<DIV><FONT face=Arial size=2> Thank you all, </FONT></DIV>
