Wrong resolution in HTML ViewInfo for PPTX in .NET

GroupDocs.Viewer Product Family
1

Calling GetViewInfo for any PPTX file does not return the correct resolution.
We want to determine the resolution of the resulting PPTX file with the code below:

using (var viewer = new Viewer(documentPath)
{
     var info = viewer.GetViewInfo(ViewInfoOptions.ForHtmlView());

But the info.Pages variable holds several pages that all have 960x540 pixels.
When I open one of the HTML files in a browser, it’s shown as 1280x720 pixels.
Are those values wrong, or do I adjust them somehow to get the expected outcome?

I tested with GroupDocs Viewer 21.5.0.
Please see the attached documents and screenshots:

Hi @Clemens_Pestuka

For now, you can use the following workaround by adding in markup:

<style type='text/css'>
.slides-canvas 
{
   width:960px;
   height:540px;
}
</style>

You may set different values of width, height in CSS if it is suitable for your case.

Thank you for the workaround. :+1:
I’ll check with my colleague who is working on the front-end if this is an option for us.
