I have noticed that any highlighted text is not rendered in the thumbnail at all. In fact, the text itself isn’t even rendered. I have tried it with text I highlighted manually in PowerPoint, as well as with text I highlighted via Aspose, but the result is the same.
I found a similar issue here, but no solution:
I am simply trying to make all text background black, preferably just the area behind the text and not the whole frame. Is there a workaround for this issue? Will it work if I try the slide.renderToGraphics() approach?
Thank you for your time,
