Validation Error: DereferenceStreamDict: wrong type <Identity-H> types.Name

[meerkat-mary]

Hi @hhrutter,

Hope you are well, we're facing an issue where pdf validation is unsuccessful due to a validation error (obj#:37): pdfcpu: DereferenceStreamDict: wrong type <Identity-H> types.Name error for two of our PDFs

We're able to open and view these files successfully in Mac Preview and Acrobat Reader on Windows 7/10 and Mac OS Ventura using the latest commit (0.4.2).

file1_output.log
file2_output.log

Please let me know if you'd like to see the original pdf file (as it contains sensitive PII information, I can email it)

Thank you!
Mary

Hi there!

For one it does not look like you are running the latest release..

Secondly this file is in violation of the PDF spec.
The ToUnicode font dict entry is expected to be a stream and not a name.
Send me the file attached to email, from the log I can see other potential spec violations.
If this is the only one needed for positive validation I am happy to relax validation.

Thanks @hhrutter - I've sent you an email containing the two files for further inspection

This is fixed as of the latest commit!
