We have a .NET 6 application with Aspose.Slides v20.7
From a pptx file containing some GIF images, after opening the file, rendering what we need and saving it, some of them results in a No Image element.
For some images it works as expected and are displayed as it is, but others get replaced for a No Image message.
Is it a known issue that has a fix? Or is there some kind of limitation?
