View Zoom Setting Is Not Working for Slide Sorter View

Trying to set the zoom slider setting (the one on the bottom right ) in Powerpoint.

I use the following sample code

ppt.ViewProperties.LastView = AsposePpt.ViewType.SlideSorterView;
ppt.ViewProperties.SlideViewProperties.Scale = 60; // Set zoom value to 60%
ppt.Save(outPath, SaveFormat.Pptx);

But after opening the file I find the zoom setting is still 100%.
Please let me know if I’m doing anything wrong here.

@tomasmuller,
Thank you for the issue description. We will reply to you as soon as possible.

@tomasmuller,
Unfortunately, I was unable to reproduce the problem you described. Please check your results using the latest version of Aspose.Slides. If the issue persists, please share the following:

  • input presentation file
  • output presentation file
  • screenshot with the problem
  • presentation file with the desired view (created in PowerPoint)

I want this setting to be changed as shown in the attached image. I hope this is what you checked for.

@tomasmuller,
If you open a presentation in PowerPoint and perform the same actions (switch to SlideSorter view, set Zoom value, and save the presentation), you will see the same result (I tested in Office 365).

But after research, I have found strange behavior in PowerPoint. Zoom value for SlideSorter view can be saved like this:

  1. Open a presentation.
  2. Switch to SlideSorter view.
  3. Set Zoom value.
  4. Switch to Normal view.
  5. Save the presentation.

It will take me a while to decide what to do with it. I will reply to you later.
