I need to hide the background images from the master slide of a single slide in PPTX. In powerpoint 2007 when you right click a slide and select Format Background there is a check box called 'Hide background graphics' which makes the slide not show the master slide objects.
I've tried the following code, but this does not work
slide.Background.Type = BackgroundTypeEx.OwnBackground
slide.Background.FillFormat.FillType = FillTypeEx.NoFill
Any ideas would be appreciated
