c# Openxml – Unable to change the slide size to 16×9 ratio

[ShrivathsanParticipant]

I am using DocumentFormat.openxml dll and refered the below link to to create a powerpoint presentation.

https://msdn.microsoft.com/en-us/library/office/gg278317.aspx

Issue : Unable to change the slide size to 16×9 ratio.

I could change the dimensions and size manually but Powerpoint is not set to 16×9.

SlideSize slideSize1 = new SlideSize() { Cx = 12191085, Cy = 6858432, Type = SlideSizeValues.Screen16x9 };

Similarly, I can set the animation effect to “Wheel” but in the powerpoint, the animation still shows as “fade”.

AnimateEffect animateEffect1 = new AnimateEffect() { Transition = AnimateEffectTransitionValues.In, Filter = “wheel(1)” };

Note: If i run the slide show then wheel animation is coming.

What am i missing or is it a known issue/behavior of the openxml.

Whatever you can do in the PowerPoint application, you can also do using Open XML.

Watch screen-cast #13 in the following series:

Introduction to Open XML

You may also be interested in the other screen-casts in that series.

Best, Eric
