Converted PDF File size exploded in slides 18.5

Hi, we’ve just upgraded from Aspose.Slides for Java 18.2 to 18.5. When running our performance tests following the upgrade, we’ve seen that some PPT to PDF conversions appear to produce PDF files that are almost double in size to the previous version. These files appear to be heavy in image content.

We would like to know if there is an expected reason for the explosion in file size? Has there be some change in image processing or compression for example?

any help appreciated.
Cheers,
Richard

@rmaurer,

I have observed the issue shared by you and request you to please share the source presentation files along with PDF files generated using both versions on your end. Please also provide the source code used on your end for producing the PDF as well.
