What's the point of transcoding? You still have to store the original DICOM right? That's probably the bulk of the cost

[tecleandor]

This is for when you receive JPEG encoded DICOMs. You transcode them to JPEG XL (saving that 20% of storage) and then, if a modality/viewer/whatever that needs JPEG requests them, they're transcoded on the flight to JPEG losslessly.

Losslessly meaning, with the same quality than the original JPEG received by the storage.
