Hello PDFBox Community,

I am trying to convert a PDF file that was previously created by JxBrowser
from an HTML source to PDF/A-1b with PDFBox. However, the validation with
veraPDF gives the error that the CIDSet is not present in the
FontDescriptor.  The fonts are embedded in the PDF and the CIDSet data also
appears to be present in the DescendantFont. However, I do not seem to have
direct access to the CIDSet data in order to be able to add it manually in
the FontDescriptor.

 

Is there a way to set the CIDSet with the data from the DescendantFont and
thus successfully pass the validation?

 

 

Validation failure

```

For all CIDFont subsets referenced within a conforming file, the font
descriptor dictionary shall include a CIDSet stream identifying which CIDs
are present in the embedded CIDFont file, as described in PDF Reference
Table 5.20

root/document[0]/pages[0](7 0 obj PDPage)/contentStream[0](19 0 obj
PDContentStream)/operators[129]/font[0](AAAAAA+ArialMT)/DescendantFonts[0](A
AAAAA+ArialMT)

```

 

Best regards

Christian
