Arabic text right alignment add extra spaces in PDF

[mgalal123]

Hi,
I am using spire.pdf.free. I have a table which has a mix of Arabic and English text and there is a need to align all text to the right. Unfortunately, when I use PdfTextAlignment.Right, a lot of spaces are added in front of the the Arabic text which is not the case if I used PdfTextAlignment.Left. This is a showstopper for me as the resulting output is not acceptable.

I am using JAVA and spire.pdf.free 5.1.0 on Windows 10 environment.

I attached the code and resulting PDFs in both case as well as screenshot with more explanation of my issue. Thanks a lot for your support.

I used another simple test based on the available samples where it shows how right alignment in Arabic is messed up.

public static void main(String[] args) {
//create a PdfDocument object
PdfDocument doc = new PdfDocument();
//add a page
PdfPageBase page = doc.getPages().add();
//create a true type font
PdfTrueTypeFont font= new PdfTrueTypeFont(new Font("Times New Roman",Font.PLAIN,15));
//create a brush
PdfSolidBrush brush = new PdfSolidBrush(new PdfRGBColor(Color.black));
//create a PdfStringFormat object, specifying PdfTextAlignment to Left
PdfStringFormat leftAlignment = new PdfStringFormat(PdfTextAlignment.Left);
//draw text at left
page.getCanvas().drawString("test 123", font , brush, 0, 20, leftAlignment);
leftAlignment.setRightToLeft(true);
page.getCanvas().drawString("عربى اسم رقم", font , brush, 0, 40, leftAlignment);
page.getCanvas().drawString("عربى اسم", font , brush, 0, 60, leftAlignment);
page.getCanvas().drawString("عربى", font , brush, 0, 80, leftAlignment);
//draw text at right
PdfStringFormat rightAlignment = new PdfStringFormat(PdfTextAlignment.Right);
page.getCanvas().drawString("test 123", font , brush, page.getCanvas().getClientSize().getWidth(), 20, rightAlignment);
rightAlignment.setRightToLeft(true);
page.getCanvas().drawString("عربى اسم رقم", font , brush, page.getCanvas().getClientSize().getWidth(), 40, rightAlignment);
page.getCanvas().drawString("عربى اسم", font , brush, page.getCanvas().getClientSize().getWidth(), 60, rightAlignment);
page.getCanvas().drawString("عربى", font , brush, page.getCanvas().getClientSize().getWidth(), 80, rightAlignment);
//save the file
doc.saveToFile("C:\\temp\\align.pdf");
doc.close();
}
