- /// ImageDataSizeRaw is the third of ImageDataSize, and there is no
- /// reason (since we called gdcmFile::SetImageData) to use the Raw image
- /// size... This "bug" in gdcmFile made that we had to black list
- /// images 8BitsUncompressedColor.dcm, OT-PAL-8-face.dcm and
- /// US-PAL-8-10x-echo.dcm...
