I am access a text frame of a slide using the findshape funciton but an unable to change the font size even using the pargraph and portions properties. I have also cast the type of the shape as a placeholder. I get not errors on the code but still the font does not change
Dim oNotes As Aspose.Slides.TextFrame = oSlide.FindShape("NOTES").TextFrame
Dim oPara As Aspose.Slides.Paragraph = oNotes.Paragraphs(0)
Dim port As Portion = oPara.Portions(0) 'Accessing the first portion of the paragraph
port.FontHeight = 15 'Setting the font height to 55
oNotes.Text = strNotes 'set the text
