Hi everyone;

I am using vtkImageActor to display slice's of DICOM datasets(I am not using
vtkImageViewer2 because when I change the slice number, it changes the z
coordinates too, but i must draw some lines on images so i couldn't use
imageviewer2). I have mapped display points to vtkImageActor's pixels,
calculated some other image pixels and now I need to convert these image
pixels to world coordinates.How can i do that? Thanks already.
