I am attempting to use the cloneSlide function to merge several presentations, but all of the textHolders are created with a solid, white background in the final presentation, despite a transparent background in the original. I have attempted to dynamically change this, after performing the copy, using the code below, without any success.
For j = 0 To sl.Placeholders.Count - 1
If TypeOf sl.Placeholders(j) Is TextHolder Then
Dim th As TextHolder = CType(sl.Placeholders(j), TextHolder)
th.FillFormat.Type = FillType.NoFill
Could you please help me by explaining this behavior and offering possible alternatives? Thanks.
