We are generating slides from MS-PPT provided layouts.
The footer with DateTime is not updated automatically on slide generation.
It shows date time of file creation/ layout creation.
Please find attached sample files.
The Footer_Backgroud_ppt.pptx is layout used to generate the slide.
The Footer_Output.pptx is generated file which shows footer with date 10/9/2012… (It should be 10/11/2012).
Code to create slide:
LayoutSlideEx ls0 = ProcessingPresentation.LayoutSlides.GetByType(SlideLayoutTypeEx.TitleAndObject);
Hope data provided is sufficient to analyze and reproduce issue at your end.
Thanks and Regards,
