Incorrect Image of Group Shape when Converting Presentation Slide to PNG in C#

Aspose.Slides Product Family

Hi,

We noticed that in Aspose 22.8 when taking an image on one of the group shapes there is additional content in the image. This was not occurring in earlier version
Attaching a sample pptx and the corresponding snapshot of the slide. sample.zip (30.1 KB)
In the above snapshot of the pptx, you can see shaded content above T in one of the group shapes

Code Snippet to reproduce the same :

for (int i = 0; i < Presentation.Slides.Count; i++)
{
	var thumbnail = Presentation.Slides[i].GetThumbnail(1, 1);
	var outPath = "pathtofile/sample_slide_" + (i + 1) + ".png";
	Console.WriteLine("generating image");
	thumbnail.Save(outPath, ImageFormat.Png);
}

Regards,
Raman

@sraman,
Thank you for reporting the issue.

I’ve reproduced the problem with the additional content when converting the slide to PNG image and added a ticket with ID SLIDESNET-43543 to our issue-tracking system. We apologize for any inconvenience. Our development team will investigate the case. You will be notified when a new release of Aspose.Slides with a fix is published.

It would be great if you could share the following additional information:

  • OS version on which the code was executed
  • .NET target platform in your app

We will then also test a solution in an environment similar to yours.
