I would like to contribute code to add support for parsing some Ricoh Exif tags in Exiv2, especially those related to image effects. I tried adding tag definition arrays like pentaxImageEffects in the code, but found it has limited effect. I am not sure how to properly implement support for these Ricoh tags.
Describe the solution you would like
I hope to get some guidance on the proper way to add support for Ricoh Exif tags in Exiv2. Specifically:
Which files need to be modified to add new Exif tag definitions?
How can Exiv2 be enhanced to fully parse the Raw file and Exif data structures of Ricoh cameras, beyond just defining tag arrays?
Are there any coding conventions or best practices I should follow while working on this?
I can help test any implemented changes. I also have some sample Ricoh Raw files that I can provide if it would be helpful.
Describe alternatives you have considered
I investigated the ExifTool code that already supports a wide range of Ricoh tags. However, directly translating that parsing logic to Exiv2 is still challenging for me. I would appreciate any pointers on how to approach this in the context of Exiv2's architecture.
Desktop
OS and version: Ubuntu 22.04
Exiv2 version and source: Exiv2 0.27.5 from exiv2.org
But I realized more extensive changes are needed for proper parsing.
Please let me know if you have any advice on how I can move forward with implementing this feature. I would be very grateful for your guidance. Also, please feel free to let me know if you need me to provide any other information or sample files.
Thank you very much for your help!

I see that it seems that the current Ricoh is analyzed under pentax,
But should Ricoh still have its own exif?
I saw on exiftool that Pentax and Ricoh have different tags, https://exiftool.org/TagNames/Pentax.html https://exiftool.org/TagNames/Ricoh.html
I suspect that this is the reason why I modified pentaxmn'int.cpp and pentaxmn'int.Hpp in the code
Still ineffective,
So I would like to ask if anyone knows how to modify this Ricoh section and what to pay attention to when adding it?
Ricoh is currently also a very popular camera. thank you all。
