Hi,

Thanks for your feedback.
We have done some tests and found that there is indeed an issue, though it appears to differ slightly from what you have reported. To help us reproduce your issue, could you please provide us with the operating system information of your host machine? In addition, please reconfirm if there are any errors in your code. Our Spire. Presentation does not provide such APIs. Thanks for your corporation.

Best regards,
Triste

Hi,

Thanks for your feedback.
Currently, we do not have a Windows 11 environment, so I tested the software on a Windows 10 system. The issues that arose during my testing differed from those you encountered, and I have attached my test results for your reference. Does this issue occur in both the local development environment and Docker?
In order to investigate this issue further, would it be possible for you to send us your complete project or image file via email? Thank you for your cooperation and prompt response.

Best regards,
