Thickness of rule not rendered accurately with Slide.getThumbnail method


I am trying to render an slide from a ppt file, which I have attached to this post. The ppt file has a horizontal rule on many slides. This rule is thick on the left end, and the thickness diminishes halfway through the rule.

When I attempt to get a thumbnail of these slides, the rule is not rendered accurately. The thickness diminishes too soon in the image generated by Slide.getThumbnail(). I have attached an example image from the first slide in the attached ppt.

Here are some other details:

Aspose jar: aspose-slides-2.3.0.jar

Metafiles jar: aspose-metafiles-1.6.1.jar

Java version: 1.6.0_21-b06

Dear James,

I have worked with the presentation file shared by you and have been successfully able to generate the slide thumbnail with no problem. For your kind reference, I have attached the generated slide thumbnail as well. I am using following jar files for thumbnail generation.

  • aspose.slides_2.3.0_20100710.jar
  • aspose.slides_2.3.0_20100710.jar
  • jai_codec-1.1.3-alpha.jar
  • jai_imageio-1.1.jar
  • jai-core-1.1.3-alpha.jar

Thanks and Regards,


Thank you for your quick response.

I looked at the image you posted, and I noticed that it has the same problem as the one that I posted. I don’t think I explained it very well in my original post. I am not concerned about the problems rendering the fonts. The problem is with the line below the title of the slide.

I have attached an image to illustrate the problem to this post… it contains two images of the first slide. The one on the top is a screenshot from powerpoint. The one on the bottom is the screenshot that you provided. On the screenshot on the bottom, I drew a circle around the problem so you can see which line I am referring to.
