CP-1678: Use of JPEG Family Transfer Syntaxes rather than RLE for YBR_FULL
100%
Description
Check whether the DCMTK correctly handles the YBR_FULL color model:
Rationale for Correction
Traditionally,the YBR_FULL Photometric Interpretation has been used only with the RLE Transfer Syntax and only for Ultrasound
images.
Further, for US images, the Planar Configuration for YBR_FULL is constrained to 1, since that is the only Planar Configuration used
for RLE.
The YBR_FULL Photometric Interpretation cannot be converted losslessly into RGB or YBR_RCT, so it is desirable to retain the
YBR_FULL encoding when decompressing or recompressing with lossless/reversible JPEG family of Transfer Syntaxes.
The JPEG family of Transfer Syntaxes use a Planar Configuration of 0, and there is no reason to constrain the Planar Configuration
of uncompressed images.
Accordingly, relax the constraint on US Planar Configuration in the IOD (but do not change the Media Application Profile).
Note that there are currently no constrains on any other IODs wrt. use of YBR_FULL, only Ultrasound, and it is desirable that archives,
toolkits and viewers be able to handle Photometric Interpretation, Planar Configuration and Transfer Syntaxes in a generic manner
regardless of the IOD.
