Any support for embedded files?

[jalevin]

Is there currently any support for embedded files?

From the looks of it, I would need to read in content streams not attached to a specific page.

Thanks

@jalevin We currently don't have a dedicated function for this like reader.GetEmbeddedFiles()..., BUT I believe it should be pretty easy to do with our current functionality.

Is your requirement to retrieve embedded files from PDF and/or embed files into PDF?

As per section 7.11.4 Embedded File Streams (p. 111 and 112 of PDF32000_2008) embedded file streams are referenced from the PDF document name dictionary. So should be able to find all the references there (not tied to a specific page). And further description of each embedded file stream is in Table 45 and table 46.

For implementation within UniDoc, I would suggest creating a model.PdfEmbeddedFile struct to contain the dictionary and methods to load and write it out.

We will need to both embed and retrieve. Looking into retrieving now.
