Right to left text

Hi,


I have a couple of questions regarding right to left aligned text:

The documentation for right to left text says “Please note that currently only normal fonts such as “Times New Roman” are supported. Specific fonts such as “Traditional Arabic” are not supported.”. Which fonts are “normal fonts”? I’ve tried using Adobe Arabic but get a NullReferenceException when I set the IsUnicode property to true, is this because Adobe Arabic is a “specific font”?

I’ve also found that when paragraphs are set to RightToLeft, they totally ignore margins that I’ve set- see the attached images. In the English image, there is a margin between the top block of text and the black border, this seems to be ignored. Similarly, the two lines at the bottom also ignore the margins I’ve set. Is this meant to happen?

Hi Nausherwan,


My template file is attached. I’ve managed to work around the margins for now so these aren’t so much an issue, but I’d be interested to know if I’m doing something wrong.

I’m still having a problem with fonts however. Arial works fine yet Adobe Arabic (which our client has requested) doesn’t work when I set the IsUnicode property to true. Please could you define what a “normal” font is?

Thank you

Hi,


I’m also having issues with combining LTR text segments with RTL text segments in the same paragraph. I have three segments-

seg0.Content = “أسبوز هو بائع عنصر ال”;
seg1.Content = “.NET not arabic”;
seg2.Content = “البارز”;

The Arabic segments are RTL and the English LTR. However, the output I’m getting is البارز arabic not .NET أسبوز هو بائع عنصر. It seems that the whole text paragraph is being aligned right-to-left rather than the individual segments?

Also, any update on which fonts can be used with RTL segments?

Hi,


Do you have an update on this? I need to let my client know whether RTL text will be possible or not.

Please share “Adobe Arabic” font with us for testing as I am unable to find this font for testing.

Sorry for the inconvenience,

Hi James,

Thanks for your patience.

In order to resolve the issue PDFNEWNET-34445 reported earlier, please try using the following code snippet.

[C#]

string outFile = "c:/pdftest/ArabicFont_Test.pdf";

Document doc = new Document();
Page page = doc.Pages.Add();

// Create a text object and pass the string object carrying Arabic text in it
TextFragment text1 = new TextFragment();

// Create a segment and add it to segments collection of text object
TextSegment seg0 = new TextSegment("أسبوز هو بائع عنصر ال");

text1.Segments.Add(seg0);

// I can't find this font for free
// seg0.TextState.Font = FontRepository.OpenFont("AdobeArabic-Regular");

// Set font size
seg0.TextState.FontSize = 14;

page.Paragraphs.Add(text1);
