annotate Core/Images/PixelTraits.h @ 3785:763533d6dd67 SylvainRouquette/fix-issue169-95b752c
add PreferredTransferSyntax to RemoteModalityParameters
DicomUserConnection can now use RemoteModalityParameters.PreferredTransferSyntax instead of using the default transfer syntax (LE-implicit).
This way we can transcode by default in LE-explicit.
fix issue #169
