Font discrepancy when ArialNarrow is used in Header text(smart text) while building a Powerpoint Presentation


We are facing an issue(font discrepancy) while building a single PowerPoint presentation for two or more reports(slides) which are built using different fonts in header text(smart text).

In this case we have built a powerpoint presentation with two reports(slides) in which source1 uses Arial font and source2 uses Arial Narrow font for header text(smart text). After exporting we could see that header text(smart text) of source2(slide2) was changed to wingdings font.

Below is the sample code snippet:-

slide = null;

Presentation source1 = new Presentation(@"C:\temp\Source1.ppt");

Presentation source2 = new Presentation(@"C:\temp\Source2.ppt");

SortedList temp = new SortedList();

Presentation m_presentation = new Presentation();

slide = source.Slides[0];

source.CloneSlide(slide, m_presentation.Slides.LastSlidePosition + 1, m_presentation, temp);


MemoryStream stream = new MemoryStream();

if (stream != null)




FileStream file = new FileStream(@"c:\temp\Cloned.ppt", FileMode.Create, FileAccess.Write);

byte[] bytes = stream.ToArray();

file.Write(bytes, 0, (int)stream.Length);

Please look into this issue and update us as soon as possible.

Thanks & Regards

Hi N Suresh Babu,

I have verified from our issue tracking system and regret to share that the issue has not yet been scheduled for investigation. Actually, our development team schedule issue related to Enterprise support customers first and then Priority support customers. After these the issues from Aspose.Slides or normal support forums are considered for resolution. The issues are scheduled for investigation and resolution on first come and first serve basis and then on the basis of their complexity. However, I have requested our development team to kindly schedule the issue for investigation and share some estimates related to issue status. I may be able to share the further information with you once it will be shared by our development team.

We are sorry for your inconvenience,

The issues you have found earlier (filed as SLIDESNET-33883) have been fixed in this update.
