Re: OpenSSL version
Hi, you can open CMakeCache.txt in the build directory to check value CMake has found for all the OpenSSL library settings (including paths). In my CMakeCache.txt file for example, the following values are found when I use my systems (here: Ubuntus) default installed openssl package: //Path to a lib...

Re: OpenSSL version
Hi Rick,
are you using a current version (commit) of DCMTK? I think Marco from the team updated OpenSSL support just recently (in February) to support versions 3.1 and 3.2, see this commit.
Best regards,
Michael

Re: lossless
Dear George, For a a different problem, please open a different thread please (next time). Regarding the file: Again it looks like you have not done any analysis yourself and did not look at what I answered earlier. The given file is *not* decompressed but compressed with JPEG 2000 (easy to spot by ...

Re: lossless
img2dcm does not apply any compression or decompression, it uses the input pixel data mostly as is.
DicomImage only uses decompression if the related decompression codecs have been registered. See dcm2pnm.cc for an example.

Re: unable to restore photo quality
It depends on the input image parameters. E.g. if Bits Stored is > 8 in the input image, and you force the image to be rendered into RGB data with 8 bit per channel (BMP), you loose information. There can also be other relevant parameters. Also there may be some typical "gotchas" that one ...

Re: PhotometricInterpretation lost
Hi George,
what do you mean, what is your expectation on how Photometric Intepretation should be handled and what happened instead? What "all other tags"?

Re: Application crashes when using DCMTK 3.6.7 in Catalina and Big Sur OS
Can't tell....
Try DCMTK 3.6.8 to make sure it's not something we have fixed -- if its a DCMTK issue.

Re: Application crashes when using DCMTK 3.6.7 in Catalina and Big Sur OS
Hi, I don't know of any problems, maybe you can did not completely recompile? You could check in the debugger to find out what exactly causes the crash. 3.6.7 has originally been tested on MacOS X 10.15 (amd64|x86_64) using Apple Clang 11.0.0 and GNU gcc 9.2.0. Note that we released 3.6.8 a few days...

Re: dicom creation
Hi,
I only understand half of the questions. To see how to create a DICOM file from regular images like BMP, see the tool (and its source code) img2dcm.
You can dump the content of a file using the tool dcmdump.
BR,
Michael

It is used (only) by dcmodify, so you can check out the link libraries used by dcmodify.

Re: File Size
The img2dcm tool can create DICOM files from BMP images. The source code demonstrates how to use the library for that.
