Code:

PresentationEx pres = new PresentationEx("d:\\pptx\\helloworld.pptx");

           

//Clone the desired slide to the end of the collection of slides in the same PPTX

SlidesEx slds = pres.Slides;

slds.AddClone(pres.Slides[0]);

 

//Write the modified pptx to disk

pres.Write("d:\\pptx\\helloworld_cloned.pptx");

Attachment:
The PPTX is attached.

Please help as we would like to make a purchase decision soon.
If there are any short-term workarounds, they are also appreciated.

Thanks.

1) When is the next release of Aspose that supports PPTX fully?

2) Upon Export - We are getting a error during cloning on this particular PPTX slide attached. See error below.

MasterSlideEx master = slide.LayoutSlide.MasterSlide;
 int index = pres2.Masters.AddClone(master);

Hi Dhananjay,

The new release of Aspose.Slides for .NET will be available by the end of June hopefully.

I have tried to clone the slide in the shared presentation and exception is thrown. But, when I have opened both of your shared presentations in PowerPoint 2007 and just saved them then I am able to clone the slides from both presentations. Can you please like to share that which version of PowerPoint has been used for the generation of these presentations? Your feedback will be important for us in resolving the issue.

Thanks and Regards,

Hi Mudassir,

1. This presentation was not created by me, so cannot provide definitive details.
As the presentation is available in PPTX format, my guess is Powerpoint 2007 was used for creating it.

-- It is available from the following URL,
https://share.acrobat.com/adc/document.do?docid=c8d08684-40e5-4059-9d38-68295ddf78e1
-- After clicking on the above link, please be patient as acrobat.com site loads and prompts you to download the file.

2. Please help with bug fixes on supporting the PPTX format
-- I have another issue open for PPTX-->PDF conversion.
-- http://www.aspose.com/community/forums/post/229138/pptx-to-pdf-fails-with-latest-.net-drop-aspose.slides-4.1.1.0-aspose.pdf-4.1.0.0.aspx

These are showstopper issues for us and stopping a purchase decision.
Hopefully, you can deliver an interim patch before July availability of the next version.

Thanks.

Hi Dhananjay,

We are extremely sorry for the delayed response.

I have requested the development team about the status of issues and awaiting their response. As soon as I receive the response from them, I will share that with you instantly.

Once again, I feel sorry for your nuisance,
