Cloning slides between pptx presentations

Aspose.Slides Product Family
1

I’m trying to clone a slide from one pptx presentation to the end of another pptx presentation.

I’m using the following code exactly as specified in the documentation:

PresentationEx pres1 = new PresentationEx(“c:/tmp/ppt/first.pptx”);
PresentationEx pres2 = new PresentationEx();
SlidesEx slds= pres2.getSlides();

slds.addClone(pres1.getSlides().get(0));
try {
pres2.write(“c:/tmp/ppt/merged.pptx”);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

However I get a NullPointerException on the slds.addClone call:
Exception in thread “main” java.lang.NullPointerException
at com.aspose.slides.pptx.SlidesEx.if(SourceFile:95)
at com.aspose.slides.pptx.SlidesEx.addClone(SourceFile:54)
at test.aspose.PptExTest.main(PptExTest.java:55)

I have verified that the presentation is valid, I have also verified that the returned slide in not null.

I have gotten the exact same error. I made two copies of the attached PPTX file and tried to clone slides from one onto the end of the other and got the mentioned error.

I am using aspose-slides-2.2.0-20100328 aspose-metafiles-1.6.1-20100110.jar and JAI 1.1.3

Edit for clarification: the PPTX was made using Office 2010.

Hi,

Thanks for your interest in Aspose.Slides.

I have been able to reproduce the issue as specified by you. I have obtained the NullPoineter exception while cloning the slides between presentations. However, if the slides are cloned with in same presentation, they are getting cloned successfully. An issue with ID 17321 has been created in our issue tracking system for further verification and resolution. This thread has been linked with the issue, so that you may be automatically notified, once the issue is resolved.

We are sorry for your inconvenience,
