DICOM @ OFFIS

Thank you for the report. We have to check this and will get back to you then.

What about creating your own sample GSPS objects using e.g. DICOMscope or Weasis.

Both serve different purposes, so SR will (most probably) never be extended by visual aspects. This is where the GSPS (and its variants for color image, etc.) comes into play: you could, of course, create an SR document (with semantically enriched numeric measurements, coded entries and the like) th...

The name indicates that this IOD is for referencing monochrome images only. The graphical annotations can also use color.

The short version of the answer is: if you want to store measurements in a semantic manner, you should use Structured Reporting (SR); if you want to store annotations in a graphical way, you could also use Grayscale Softcopy Presentation States (GSPS). In terms of what is easier to use, e.g. by just...

Did you already try to use a double backslash, i.e. "\\" instead of "\"?

I am not familiar with PowerShell, but the dcmj2pnm manpage (in HTML format) can e.g. be found here: https://support.dcmtk.org/docs/dcmj2pnm.html

After discussing it with the team, I've created an entry in the DCMTK issue tracker: https://support.dcmtk.org/redmine/issues/1046

Maybe, you are right. Currently, it is only documented in the source code. Here is some background information: At the time when I implemented support for overlay rendering (more than 25 years ago), there were many uncertainties in the DICOM standard regarding "color overlays", especially regarding ...

The short answer is: dcmj2pnm does not support rendering of overlay planes in color (e.g. RGB) images. It only works for monochrome DICOM images.

If you don't want to disable the debug and trace logger of the dcmdata module completely, it would probably be the best approach to introduce a new (sub-)logger (e.g. "dcmtk.dcmdata.protected") for the information concerned. You could then disable (or redirect) only this logger. Maybe, this approach...

Since there are no VOI LUT settings in the DICOM data set, it is up to the viewer (rendering tool) to select appropriate settings. The tool dcmj2pnm provides the following options for this purpose: VOI LUT transformation: -W --no-windowing no VOI windowing (default) +Wi --use-window [n]umber: intege...

Could you make a DICOM sample file available for download?

In more recent DCMTK versions, the stderr stream is no longer merged with stdout (on Windows systems). That means, if you want to redirect stderr to a file you could e.g. use "2> logfile.txt" or "2>&1 logfile.txt".
Alternatively, you could use an appropriate logger configuration.

Thank you. I'll check your new proposal as soon as time permits...
