ClassCastException on generating a thumbnail from pptx file

Aspose.Slides Product Family

Hi,



I am getting the following exception:





java.lang.ClassCastException: com.aspose.slides.pptx.GradientShapeEx cannot be cast to com.aspose.slides.obfuscated.agt

at com.aspose.slides.FillParam.do(SourceFile:323)

at com.aspose.slides.FillParam.if(SourceFile:123)

at com.aspose.slides.FillParam.(SourceFile:101)

at com.aspose.slides.pptx.BaseSlideEx.for(SourceFile:206)

at com.aspose.slides.pptx.SlideEx.do(SourceFile:161)

at com.aspose.slides.pptx.SlideEx.getThumbnail(SourceFile:263)







The snippet of code that is generating this exception is:





for (int i = 0; i < slides.size(); i++) {

SlideEx sl = slides.get(i);

BufferedImage image = sl.getThumbnail(1.0f, 1.0f);

…

}







The pptx file causing the exception is attached.



And, the versions of jar files I am using are:

aspose-metafiles-1.6.1.jar

aspose-slides-2.2.0.jar

Dear James,

I have tried to generate the slide thumbnails using Aspose.Slides for Java 2.3.0 and have successfully been able to generate the thumbnails. For your kind reference, I have attached the generated slide thumbnails. Please proceed to download section to download the latest release of Aspose.Slides for Java 2.3.0.

Thanks and Regards,
