Is RTL Text operation available with Aspose.Slides?


I want to replace the texts in various languages to RTL language strings read from right to left, but it doesn’t seem like it is as I tested with the code below.
I set Presentation.DefaultTextStyle.DefaultParagraphFormat.RightToLeft = NullableBool.True.
How can I replace the texts correctly to any RTL languages I want?

Please find the attached data (52.5 KB) contains the input/output files I used below.

.Net core 2.1/Aspose.Slides 19.5.0

Presentation pres = new Presentation("hello.pptx");
pres.DefaultTextStyle.DefaultParagraphFormat.RightToLeft = NullableBool.True;
foreach (ISlide sld in pres.Slides)
	foreach (IShape shp in sld.Shapes) 
		string typeName = shp.GetType().Name;
		if (typeName == "AutoShape")
			((IAutoShape)shp).TextFrame.Text = "مرحبا بالعالم";
			((IAutoShape)shp).TextFrame.TextFrameFormat.AutofitType = TextAutofitType.Normal;
pres.Save("hello_1.pptx", SaveFormat.Pptx);

My own question posted below on another thread is evoked from the same purpose; I want to replace the text in other languages, correctly.



I have worked with source file and have been able to observe issue. A ticket with ID SLIDESNET-41363 has been created in our issue tracking system to further investigate to resolve the issue. We will share good news with you soon.


Can I expect some other RTLs such as Persian/Farsi, Hebrew, and Urdu, not only Arabic, would be covered when the ticket SLIDESNET-41363 is resolved?



I have mentioned this in ticket and will share good news with you soon.
