Native camera data matrices and MIL-STD-130N

jet_silver

TIL that camera v.90 can read a lot of matrices, but not IUIDs per MIL-STD-130N. ECC 200 matrices are readable. Is there / is it foreseen that a way to allow compliance including the non-printing characters for group and record boundaries is / will be available?

jet_silver My very quick glance at MIL-STD-130N suggests IUIDs can be encoded as data-matrix or as GS1-128. Is the issue at hand that the GrapheneOS camera won't scan GS1-128 bar codes? Is it possible to identify one of the examples from the MIL-STD-130N spec that is scannable and one that isn't?

GrapheneOS

jet_silver We use the Java ZXing library which is unfortunately in maintenance-only mode and very unlikely to gain support for new formats. They accept pull requests with bug fixes and minor improvements but nothing more.

The project is in maintenance mode, meaning, changes are driven by contributed patches. Only bug fixes and minor enhancements will be considered. The Barcode Scanner app can no longer be published, so it's unlikely any changes will be accepted for it. It does not work with Android 14 and will not be updated. Please don't file an issue for it. There is otherwise no active development or roadmap for this project. It is "DIY".

Many apps are moving to using a Google Play services library for this, which we won't:

The list of formats for the Google Play library is here:

GrapheneOS It seems that there is a vaguely-active Rust port: https://github.com/rxing-core/rxing
