Hello,
Thanks for your inquiry.
I simulated a PDF file and conducted preliminary testing using the latest version of Spire.PDF(
Spire.PDF Pack(Hot Fix) Version:9.9.9), but did not reproduce your issue. If you are not using the latest version, I suggest you use the latest version for testing first. If the issue still exists after testing, please provide the following information for further investigation. Thank you in advance.
1)Your sample PDF file, you can attach here or send it to us via email (
support@e-iceblue.com).
2)Application type, such as Console App, .NET Framework 4.8.
3)Your test environment, such as OS info (E.g. Windows 7, 64-bit).
Sincerely,
Annika
