Hello, this is a good idea.

I just did some experimentation and found a solution to add assets as attachments to the PDF, but I can't hyperlink the original asset to the attachment.

Even in the current implementation with external assets, the links don't resolve correctly with the http://127.0.0.1/.. link in there. It probably need to be changed regardless.

You're right, but currently we haven't figured out how to point a hyperlink in a PDF to a local file.

For the external assets at least, I tested with a different pdf generator and the following links resolve correctly file:///home/vagaruy/Desktop/assets/test_file . I haven't been able to test with embedded attachments yet however.

Can you help to test whether a relative path can be generated?

After some exploration, we have found a technical solution to change the asset of the http://127.0.0.1 server to a local relative path and link it to the assets folder.

For example, when placing pdf and assets on the desktop:

When we move the pdf and its assets, the relative path still works fine:

Finally, we found a way to jump to embedded attachments, and unified improvement in this issue, thank you.

thank you for the great work on this.

The previous hyperlink cannot be clicked, you need to double-click the attachment annotation to open the attachment.

I tested the pre-release siyuan-v202302231520-linux.AppImagewith the fix but there seems to be some problem with the embedding. The links still point to http:// and the files are not embedded either.
Attached a screenshot of the incorrect link.

Thanks for testing, we will fix it later.

Hello . I recently tried testing this on 2.10.2 and the embedding asset don't seem to be working anymore.

@vagaruy It will be fixed in the next version, thanks for the feedback.
