You can find a 'color' version of vtkImageMapToWindowLevelColors
within gdcm itself: vtkImageMapToWindowLevelColors2

<pre wrap="">Hi,
I am currently calculating window-level values of an image actor from user
selected brightness and contrast levels. I pass these values to
vtkImageMapToWindowLevelColors::SetWindow and
vtkImageMapToWindowLevelColors::SetLevel methods. The brightness and
contrast works, but it always outputs a greyscale image. How can I get it to
do the window-level modifications and still output a color image? (Just like
in vtkImageViewer but I noticed it uses vtkImageMapper which does
vtkImageMapper::SetColorWindow - is there a difference?)
Am I not setting up my lookup table properly? Not sure what the problem is.
Thanks
John E

Hi Mathieu,
You were right. The dicom file was compressed. I have used the
gdcmconv
cmd to uncompress it.
Thank you very much for your useful information.
Best.

If you can read it with Slicer, this means this is a proper DICOM file
but vtkDICOMImageReader only handles:
...
Warning:
This reader might eventually handle ACR-NEMA file (predecessor of
the DICOM format for medical images). This reader does not handle
encapsulated format, only plain raw file are handled. This reader also
does not handle multi-frames DICOM datasets.
...
Have a look at vtkGDCMImageReader which will handle you file (I would
bet this is a compressed data).

If you cannot integrate gdcm into your project you can use gdcmconv
--raw to decompress the image and make it compatible with
vtkDICOMImageReader
