Hi,
Thank you for your inquiry and sorry to reply late for weekend.
I simulated PDF files with rectangle and tested with the latest
Spire.PDF Pack (8.11.2), but didn’t reproduce your issue. If you were not using the latest Spire.PDF, I suggest that you give the latest one a try. If the issue still occurs, please provide the following information for our further investigation. You could attach your files here or send to us via email (
[email protected]). Thanks in advance for your assistance.
1. Your sample PDF files and test code
2. Test environment (For example, Windows10 64bit)
3. Your application type (For example, Console app .NETFramework 4.7.2)
Sincerely,
Doris
