Option to Bypass Thumbnail Generation on Saving a Presentation in C#

Aspose.Slides Product Family

Hello,

Our application experiences a performance bottleneck in the Presentation.Save method. While profiling the app we noticed that a significant amount of time is spent in a method called Slide.GetThumbnail.

We would like to know if there is an option to bypass thumbnail generation to optimize the save time. Currently, we could not find a SaveOption that allows us to disable this feature (Aspose.Slides 24.9.0)

You can observe this issue by running the following code snippet:

var p = new Presentation("./lorem.pptx"); // can be any presentation
p.Save("./lorem2.pptx", SaveFormat.Pptx);

Profiling the above program in dotTrace showed that ~38% of the time is spent generating the thumbnail.
