Bad thumbnail rendering



I use “aspose-slides-19.2-jdk16.jar” to generate png thumbnails of slides but the result is not completly similar to the source.

Can you explain why aspose show the word “mind” from “momindum” with a fade opacity ?

Can you explain why aspose highlight in yellow the word “Momindum” ?

Thank you in advance for your help.

Best regards.


I have worked with source file shared by you using Aspose.Slides for Java 19.4 and have been able to observe issue. A ticket with ID SLIDESJAVA-37637 has been created in our issue tracking system to further investigate issue in detail. This thread has been linked with issue so that you may be automatically notified once issue will be fixed.

However i have not been able to observe following issue. Because word “Momindum” is yellow in source file as well, i have opened this file using PP 2016. Can you please share your PP version so that we may further investigate to help you out. For reference i have also shared my generated result with you.Slide_1.png (7.8 KB)


You right about the second case, if I open the google-slides-presentation.pptx into PP 2016, I see same as yout, the text is highlighted in yellow.
It seems to me, the problem comes from the Google Slides exportation function in pptx format and not from aspose library.

Thank you very much for your quick reply.



You are very welcome.


Good afternoon,

Did you have any news about this case?




I like to inform that this issue will be resolved in Aspose.Slides 19.6, which will be released soon. I request for your patience. We will share good news with you soon.

Have a nice day.
