DICOM @ OFFIS

I assume it is possible via source code/library.

This is one option. Another one would be to write the output of dcmdjp2k to stdout and pipe the data to dcm2pnm, but this would require the latest development snapshot of both tools.

Also, decompressing the JPEG 2000-compressed image first to an uncompressed DICOM image and storing it as a DICOM file in the file system before processing the uncompressed DICOM file with dcm2pnm is probably not the most efficient way of doing it.

Sorry for the confusion, +wb was a typo. I wanted to write +ob, which is just the short version of --write-bmp.

I am guessing for extending the tool you need the source code access package.

Correct.

So, I have to chain the conversion. <dicom file with compressed JPEG 2000 image> → dcmdjp2k → <dicom file with decompressed JPEG 2000 image> → dcm2pnm → <bmp file>. This is correct, unless you extend the command line tool dcm2pnm with JPEG 2000 support, which is rather easy if you've licenced DCMJP...

Then, the answer is easy: as you can read in the documentation, the public DCMTK does not support JPEG 2000 compression (e.g., there is a list of supported Transfer Syntaxes in the manpage of each tool). If you want to decompress JPEG 2000 compressed images (or compress DICOM images with JPEG 2000),...

What is the Transfer Syntax of the DICOM dataset?

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 ...
