Palette Color LUT with 8 bits per entry not supported? #173

Open jriesmeier opened 8 months ago

jriesmeier commented 8 months ago

I tried to load a DICOM multi-fluorescence WSI with the Palette Color Lookup Table Sequence (0048,0120) from the Optical Path Module present. However, this does not seem to work if the number of bits per table entry is 8.

Here is the relevant excerpt from the DICOM dataset:

(0048,0105) SQ (Sequence with explicit length #=1)      # 1744, 1 OpticalPathSequence
  (fffe,e000) na (Item with explicit length #=6)          # 1736, 1 Item
