Spire.PDF for .NET 9.2.6 32bits System.OutOfMemoryException

[RaphaelBCgm]

Hello,

We are using Spire.PDF to modify pdf documents in our 32 bits .NET application and periodically, on some environment, we encounter System.OutOfMemoryException. We are using .NET framework 4.7.2 and Spire.pdf 9.2.6. We currently are not planning to migrate our application to 64 bits. The code throwing the exception is as below :

using var stream = currentAssembly.GetManifestResourceStream(sourcePdf);
using var doc = new PdfDocument();
doc.LoadFromStream(stream);

Hello,

Thanks for your inquiry.
According to the information you provided, we suggest that you use the latest version of Spire.PDF(Spire.PDF Pack(Hot Fix) Version:9.5.4) for testing first. If the issue still exists after testing, please provide us with your input PDF file(If the file size is too large, you can provide us with an online download link) and complete executable code for further investigation. You could attach them here or send them to us via email ([email protected]). Thanks in advance.

Sincerely

Hi,

thanks for your reply. Here is the input pdf file, it is only 3 pages long so it is unlikely the source of the problem.

Best regards
Raphael

Hello,

Thank you for your feedback.
As your provided code cannot be executed directly, I made some simple modifications to it so that it can run. After testing, I couldn't reproduce the issue you mentioned. I have attached my test code and result file for your reference. If the problem still exists after your testing, please provide a simple test project (that can reproduce the issue) for us to further investigate. You could attach it here or send it to us via email ([email protected]). Thanks in advance.

Sincerely
