I want to read in a raw 24bit color image (2048x1216, three channels, planar RGB). The tcl code below produces a tiled gray-scale image. Should I have some sort a lut in between the reader and the viewer?

Thanks,

Goodwin

vtkImageReader reader
reader SetFilePrefix "../image"
reader SetFilePattern "%s%d.raw"
reader SetDataExtent 1 2048 1 1216 1550 1550
reader SetDataSpacing 0.33 0.33 1.0
reader SetNumberOfScalarComponents 3
reader SetDataScalarTypeToUnsignedChar
reader SetDataByteOrderToBigEndian

vtkImageViewer viewer
    viewer SetInput [reader GetOutput]
    viewer SetColorWindow 255
    viewer SetColorLevel 127.5
    viewer Render
