<DIV>Hi all,</DIV>
<DIV> </DIV>
<DIV>I have read an initial 3D image from a file with itkImageFileReader and displayed with VTK through vtkImageData/vtkImageActor.</DIV>
<DIV> </DIV>
<DIV>Now, since a known world position in 3D x,y,z, I would like to retrieve the pixel value at this point of my image. </DIV>
<DIV> </DIV>
<DIV>This seems to be a complex problem, because I don't want the pixel data that is displayed at this position but the pixel data of the raw image, that is no rescaled instead.</DIV>
<DIV> </DIV>
<DIV>Is there some example where such a thing is done? Or any function? </DIV>
<DIV> </DIV>
<DIV>Thanks, </DIV>
<DIV> </DIV>
