I have found issues in PDF conversion results with the latest 18.11 version of Slides for Java library. The issue is related to transparent images.
The previous version 17.8 was working properly.
To reproduce the issue, I’ve attached a ZIP file containing a small java program that generates PDFs from various source PPT files, with one slide only but with different details. The PDFs are generated with both 17.8 and 18.11, in order that you can compare the differences in conversion.
Many thanks in advance.
Regards.
