java itext create pdf with hebrew (rtl) and english

问题

I want to create a pdf document containg english and hebrew together , I can see hebrew letters by using: BaseFont unicode = BaseFont.createFont("c:/windows/fonts/arialuni.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED); but i see them in reverse. I want to be able to show the hebrew strings in rtl mode , and that the english strings will stay in ltr mode.

how can this be done? Is there an example of english and hebrew together? (or any other rtl languge).

Thank's In Advance.

You should be able to draw your text via an instance of ColumnText and get full BiDi support. You just need to setRunDirection to something other than PdfWriter.RUN_DIRECTION_DEFAULT.

You might be able to get the same effect with ColumnText.showTextAligned() using the longer version with a non-default run direction:

ColumnText.showTextAligned(contentByte, Element.ALIGN_LEFT, myParagraph, x, y, rotation,
  PdfWriter.RUN_DIRECTION_LTR, 0);

This sets LTR as the default direction, and activates BIDI processing. Within a ColumnText, RUN_DIRECTION_DEFAULT is the same as RUN_DIRECTION_NO_BIDI.
