Description

Lines like const unsigned long ocnt = OFstatic_cast(unsigned long, inter->getAbsMaxRange()); in DiMonoOutputPixelTemplate (dcmtk/dcmimgle/dimoopxt.h) limit the number of LUT entries to what is representable by an unsigned long (Uint32 in most cases). These lines should be identified and changed to size_t instead.
