Is there way to mix the font sizes or styling of text within a single TextRange? For example, how would I add text formatted in this way to a TextRange:

Here is my text. Only a few words are in bold, and some are underlined.

It seems that I am only able to change these properties for the entire TextRange.

Hello,

Thanks for your inquiry.
There is way to mix the font sizes or styling of text within a single TextRange. You can extract the texts that you want to set the format. Next,set its format and append them to paragraph. Please try the following code.
Code: Select all
            Presentation ppt = new Presentation("Sample.pptx", FileFormat.Pptx2010);
            IAutoShape shape = ppt.Slides[0].Shapes[0] as IAutoShape;
            string originalText = shape.TextFrame.Text;
            string[] splitArray = originalText.Split(new string[] { "bold", "underlined" }, StringSplitOptions.None);
            TextParagraph tp = shape.TextFrame.TextRange.Paragraph;
            tp.TextRanges.Clear();
            //normal text
            TextRange tr = new TextRange(splitArray[0]);
            tp.TextRanges.Append(tr);
            //bold text
            tr = new TextRange("bold");
            tr.IsBold = TriState.True;
            tp.TextRanges.Append(tr);
            //normal text
            tr = new TextRange(splitArray[1]);
            tp.TextRanges.Append(tr);
            //underline text
            tr = new TextRange("underlined");
            tr.TextUnderlineType = TextUnderlineType.Single;
            tp.TextRanges.Append(tr);
            //normal text
            tr = new TextRange(splitArray[2]);
            tp.TextRanges.Append(tr);
            ppt.SaveToFile("Result.pptx", FileFormat.Pptx2010);
