> hello,everyone
>      I have faced a new problem. MR image`s gray value is 12 bit(0-4095), which is different from general gray value image, whose gray value is 8 bit(0-255). Thus I have to preprocess the MR Image to make sure the image information lager than 8 bit (256) could be showed on the PC screen. Dose VTK have the function to deal with the image processing problem. If not ,how could I deal with this problem without VTK`s help !

Hi vtkdicomer,
