I have observed the sample code. You are trying to generate the thumbnail on your end. Please first try using latest Aspose.Slides for Java 19.2 on your end and if there is still an issue then please share the source presentation, Java and operating system details on your end.


I have just upgraded Aspose.Slide to 19.2 and tested but no success.

Java: jdk16 (added classifier in maven pom.xml)
OS: Ubuntu (49.5 KB)
