Questions tagged [gdcm]

Grassroots DICOM (GDCM) is a cross-platform library written in C++ for DICOM medical files. It's automatically wrapped to Python/C#/Java & PHP (using swig). It supports RAW, JPEG (lossy/lossless), J2K, JPEG-LS, RLE and deflated. Parts 3, 6 & 7 of the DICOM standard are included as XML files. GDCM can be used to build a JPIP or WADO server. Questions about just using the bundled applications are off-topic for Stack Overflow, unless programming specific.
