We are sorry for the inconvenience.

The issues you have found earlier (filed as PDFNET-53032) have been fixed in Aspose.PDF for .NET 23.2.

I’m experiencing a similar issue using Aspose.PDF for Java 22.12. I don’t see version 23.2 available for Aspose.PDF for Java and updating to 23.1 didn’t help. Will this be addressed in the java library?


Every fix and improvement in 23.2 version of .NET API will be ported into Aspose.PDF for Java 23.2. Next update of the Java API is currently being prepared and is expected to be released next week. You can try once its available and share with us in case you still face any issues.

Thanks for your response! Do you happen to know the expected release date for Aspose.PDF for Java 23.2?


Aspose.PDF for Java 23.2 has just been released.
