'Invalid font name' error when extracting text from certain PDF

GroupDocs.Parser Product Family
1

Hi,

When using the Parser to read all text of certain PDFs, we’re getting the following error:

System.ArgumentException: ‘Invalid font name’

We were using Perser from GroupDocs.Total.NetFramework 26.6 with that code:

            using (var parser = new Parser(documentPath))
            {
                using (TextReader reader = parser.GetText())
                {
                    string strText = reader.ReadToEnd();
            ...

Can you please give it a try with the attached files:
626 WR-Docs - 51097-1.pdf (218.7 KB)
596 WR-Docs - 51231-1.pdf (162.6 KB)
618 WR-Docs - 51231-1.pdf (162.7 KB)

Thanks!

Best regards,
Clemens

Hi @Clemens!

Thank you for reporting this issue. We reproduced this issue and made fixes to deliver in the next October Release

The issue comes from the invalid PDF page content generated by the legacy Gnostice PDFtoolkit.
Strictly, such pages are not valid PDFs, because a font name must resolve in the page’s own resources.
Thank you!
