Detailed Description

JPEG codec Class to do JPEG (8bits, 12bits, 16bits lossy & lossless). It redispatch in between the different codec implementation: gdcm::JPEG8Codec, gdcm::JPEG12Codec & gdcm::JPEG16Codec It also support inconsistency in between DICOM header and JPEG compressed stream ImageCodec implementation for the JPEG case.

Note: Things you should know if you ever want to dive into DICOM/JPEG world (among other):
