Re: Adding Private Tag Data to the private.dic File

this is correct. Did you check that the environment variable DCMDICTPATH really points to your private dictionary?

FAQ #24: How to access original pixel data using class DicomImage?

:?: How do I access original pixel data (e.g. Hounsfield Units for CT) using class DicomImage? :!: Until recently, there was no (official) way to access the internal pixel data representation of DicomImage. The main purpose of this class (and module dcmimgle/dcmimage in general) is visualization and...

FAQ #22: Why do the C++ source files use different extensions on Unix and Windows?

:?: Why do the C++ source files use a ".cc" extension in the Unix version of DCMTK, but a ".cxx" extension in the Windows version? :!: The ".cc" extension is there mostly for historical reasons - this is the naming scheme we adopted when we initialized our code maintenance system. Unfortunately, not...

FAQ #19: Network transmission is very slow

:?: The transmission of DICOM objects to the storescp or imagectn application works but is incredibly slow - about one 512k image per 15-20 seconds. :!: The problem is most likely related to reverse DNS lookup. When accepting an association, DCMTK attempts to find out the remote system's hostname. T...
