Hi Mohamed,

Thanks for your inquiry. I am afraid I am unable to check your shared PPTX due to 0 KB size. However, I have converted your shared PDF to PPTX using Aspose.Pdf for .NET 10.9.0 and noticed that first text line is left aligned however not in reverse order and last page is not rendering. Please check attached PPTX and confirm whether you are facing same issue or some other, so we will log the issue accordingly for further investigation and rectification.

We are sorry for the inconvenience caused.

Best Regards,

Hi Mohammed,


Thanks for sharing the resource files.

I have tested the conversion of PDF to PPTX using Aspose.Pdf for .NET 10.9.0 in VisualStudio 2010 project running over Windows 7 (x64), where I have used a valid Aspose.Pdf for .NET license and as per my observations, the Arabic text is properly rendering inside PPTX. for your reference, I have also attached the output generated over my end.

Hi Mohamed,


Thanks for your patience.

We have further investigated earlier reported issue and it appears to be a known issue.

The first point is to identify what direction for Arabic text is right.


We have situation that PowerPoint-2010
and PDF viewers like Adobe Acrobat, Foxit Reader etc. display text in left-to right direction but PowerPoint-2013 displays text in opposite direction. The main problem here is that text rendering libraries like Pango library show this text in right-to-left direction,
like Power-Point-2013 does.

It occurs because all this soft use font with special feature - “OpenType Layout”. This feature causes an arabic text to be rendered in backward direction.
Why PowerPoint-2010, Adobe Acrobat and other PDF viewers doesn’t apply this feature to text? They all can do it but problem text from input document “Farag.pdf” is attached to special embedded font “Times New Roman”. This embedded font is not the usual “Times New Roman” font, it’s only a limited version of it.

This limited font has no OpenType Layout feature in it’s binary data and due to it Acrobat and other soft can’t apply this feature to text and get backward direction.
Why PowerPoint-2013 can apply this feature? My be it use font substitution and gets usual
Times New Roman font for text rendering (Pango library used usual, not-limited “Times New Roman” font in tests).

So at this step we have situation that we can’t “force” PowerPoint-2013 to draw text in usual direction. It will use OpenType Layout feature which orders text to be rendered in backward direction and we can’t “turn off” this feature on PowerPoint-2013 side.
Only one thing that we can do here - it’s an implementation of OpenType Layout support and special font substitution to get font which has OpenType Layout feature. After this implementation text will be rendered in backward direction in both PowerPoint-2010 and PowerPoint-2013, what is wrong by customer’s requirement.

Also implementation of OpenType Layout for Arabic text is a difficult task which requires much time. We haven’t time resources enough for only one task and it was decided to implement this feature only when it would be required by several priority tasks.
