transfer syntax and chooseRepresentation

[hmmr]

I want to change transfer syntaxes of the dataset and send it's by DcmSCU::sendSTORERequest(), but it's failed because chooseRepresentation() don't convert pixel data in real time.
How can I change TS of the pixel data without save dataset on the disk?

please check if you registered required codecs by RegisterCodecs, for example DJLSEncoderRegistration::registerCodecs
take a look at dcmimage/apps/dcm2pnm.cc

Also you may look at storescu when the compiler flag ON_THE_FLY_COMPRESSION is defined.

Thank you. The mistake was in another class, which prepares the data for dcmscu.
There calls deregistercodecs in the destructor.
