Setting Portion FontBold property

Hi All.

I am having an issue setting the FontBold property of a Portion using the code below -

Paragraph critDescBullsParaB = critDescBullsTF.Paragraphs[0];

Portion b = critDescBullsTF.Paragraphs[0].Portions[0];

b.Text = "bold text ";

b.FontBold = true;

b.FontUnderline = true;

The resulting text is underlined but not bold.

Anyone got any ideas if I’m missing something?



Hi John,

Thanks for showing keen interest in Aspose.Slides.

During my test with the following code, I am unable to notice this issue. The version I am using is 4.1.0


Presentation pres = new Presentation();
Slide sld = pres.Slides[0]; // pres.AddTitleSlide();

Aspose.Slides.Rectangle Header_rect = sld.Shapes.AddRectangle(420, 1345, 4900, 920);

//Hiding the lines of rectangle
Header_rect.LineFormat.ShowLines = false;
Header_rect.AddTextFrame("Hello world");
Header_rect.TextFrame.Paragraphs[0].Portions[0].FontUnderline = true;
Header_rect.TextFrame.Paragraphs[0].Portions[0].FontBold = true;

//Writing the presentation as a PPT file

Hi Mudassir.

Thanks for responding so quickly…

Seems to be an issue with which version of Powerpoint used to view the presentation. Using the Powerpoint viewer or Open Office (v2.2 and v3) the bold is not honored but the underline is. Using Office 2008 for Mac the bold and the underline is honored.

Not sure exactly how to proceed with this…
