.NET PPT to PDF unknown pixel format

I have encountered an issue with converting certain ppt files to pdf. During the conversion process an exception will get thrown on certain ppt files that say “Unknown pixel format.” I have attached a test app along with the 2 problem ppt files that are affected by this issue in the project folder.

Aspose slides 18.3.0.0

PixelFormat.zip (1.4 MB)

@HylandRendering,

I have worked with the presentation file shared by you using Aspose.Slides for .NET 18.12 on my end and have not been able to observe the issue. I request you to please try using the specified version on your end. I have also attached generated PDF as well for reference.

It appears the document converts but, the image is missing from the final PDF. I also tried locally with enabling the license.

Example before and after.
