Version of openjp2 causing issue in new projects

[cstrickland-pag]

This is an issue I am only getting on new projects. I have the same dependencies including version in an older project that works without error. Below is a simplified set of steps that can reproduce the issue. I did notice different versions of sub-dependencies in Cargo.lock file. Specifically in older project, with the same dependency versions I get:

jpeg2k: 0.6.6 vs 0.6.7 openjpy: 0.3.0 vs 0.3.4

To replicate (running on Linux, cargo 1.76.0 ):

• cargo new test-project
• cd test-project
• cargo add --features pixeldata

This creates the following dependencies in the Cargo.toml [dependencies] dicom = { version = "0.6.3", features = ["pixeldata"] }

Then run:

• cargo check

Please let me know if I you would like me to supply any more information on this issue? Any help on this would be greatly appreciated.

Thank you for reporting. This has also been brought up on our Zulip (ref). It seems that some recent patches to openjp2 broke the integration with DICOM-rs. Ideally this should be reported and patched at the 0.3.x line of openjp2.

Until then, you should be able to require exact versions which are likely not to have the problem.

[dependencies]
jpeg2k = { version = "=0.6.6", default-features = false }
openjp2 = "=0.3.1"

Thank you for the information. By adding the additional dependencies you have suggested, I can successfully work around the issue.
