Thanks for your interest in our API’s.
The issue related to StackOverFlow depends upon particular scenario in which API is being used and it also depends upon the input file being used. However we suggest you to please try downloading the latest release of Aspose.Pdf for .NET 10.7.0 and try using it. You may also consider requesting a 30 days temporary license to test the API without any limitations. Get a temporary license
In case you face any issue, please share the resource files and code snippet, so that we can test the scenario in our environment.
