Unable to create thumbnail from slide containing Do not autoscale textbox


I’m having a strange issue, this was previously report in 510591.

When a slide contains a text box with 2 columns and set to ‘Do not autoscale’
AND text does not completely fit the text box size.
Code that never returns on GetThumbnail():

This problem still exists. It actually has to do with getting thumbnail from the slide in “Release” mode. When I run the same code in Debug mode, all works OK.

If you try this code, its very easy to reproduce. I am using version of Aspose. But please remember to run it in Release mode.


Aspose.Slides.Presentation pres = null;

//Create a new presentation based on a template.

pres = new Aspose.Slides.Presentation(“asposefile.pptx”);

System.Console.WriteLine(“File Opened”);

Aspose.Slides.ISlide[] slides = pres.Slides.ToArray();

Aspose.Slides.ISlide sld = slides[0];

System.Console.WriteLine(“About to Image…”);

System.Drawing.Image slide = sld.GetThumbnail(1, 1);


pres = null;
