Description

Currently, the DcmFileFormat constructor accepting a DcmDataset* always creates a copy. This is ok in many cases but a little inefficient if the DcmFileFormat instance is only created to save the dataset to a file (with meta header). See e.g. this commit.

Attached is a patch, that allows for specifying whether to create a copy or just reference the given dataset.

This new feature would be especially helpful for the SCU/SCP classes in "dcmnet", e.g. when storing a received DICOM dataset. However, deleting the passed DcmDataset during DcmFileFormat destruction might not always be desired since the dataset is still in use ...
