Hi @all,
if i try to convert a ppt or pptx file to pdf, the following error is thrown:
com.aspose.slides.PptxException: This export format is not implemented for PPTX yet
code is from the api-example https://docs.aspose.com/display/slidesjava/Converting+a+Presentation#ConvertingaPresentation-ConvertingPresentationtoPDFusingtheDefaultOptions
Presentation pres = new Presentation(“demo.pptx”);
pres.save(“demoDefault.pdf”, SaveFormat.Pdf);

I have observed the issue shared by you and request you to please share the source presentation creating issue on our end. I will be able to investigate the issue further on my end on provision of requested information.
Hi Mudassir Fayyaz,
i attached my two example files.
Musterdateien.zip (54.0 KB)
There´s only one differenz between the Aspose-example and my coding.
I create the Presentation object via InputStream:
Presentation presentation = new Presentation(ifile.getInputStream());

If I can provide more details, please let me know
I have observed the issue shared by you and request you to please provide the sample java file (zipped) that is reproducing the issue and that we can use in our environment. If you are using some other Aspose product in same java file?
Please also try using com.aspose.slides.SaveFormat.Pdf instead of SaveForamt.Pdf as well.
you made my day 
Due to using multiple Aspose products, my SaveFormat.Pdf was from the package com.aspose.words
Now with com.aspose.slides.SaveFormat.Pdf it works.
Kind regards,
Vincent
It’s good to know things are working fine on your end. Please share, if I may help you further in this regard. Have a nice day.
