Hi,
Thank you for your inquiry.
I did an initial test using the latest version(
Spire.PDF Pack(Hot Fix) Version:8.4.15), but didn't reproduce your problem. I suggest you give the latest one a try. If the problem still exists, please provide the following information for further investigation. You can attach your file here or send it to us via email (
support@e-iceblue.com). Thanks in advance.
1) Your PDF test documents and images
2) Test environment, such as Win10, 64bit
3) Application type, such as Console App, .NET Framework 4.8
Sincerely,
Kylie
