how to extract pattern picture from PatternFormatEx?

but in PresentationEx i can`t find same property.

Dear Andre,

I have been able to observe the error message reported by you while opening the PPTX in PowerPoint 2010. An issue with ID 19733 has been created in our issue tracking system to further investigate the issue. This thread has also been linked with the issue, so that you may be automatically notified, once the issue is resolved.

Secondly, PresentationEx.Images property can be used to access the pictures inside the PPTX. This property is equivalent to Presentation.Pictures in PPT. For further information, please visit this documentation link.

Thanks and Regards,
