does openpdf support alignment at both ends

[maozhen520]

hello, does openpdf support alignment at both ends? please,
Now, the align-related code looks like this:

public static void showTextAligned(PdfContentByte canvas, int alignment, Phrase phrase, float x, float y, float rotation, int runDirection, int arabicOptions) {
       if (alignment != Element.ALIGN_LEFT && alignment != Element.ALIGN_CENTER
           && alignment != Element.ALIGN_RIGHT)
           alignment = Element.ALIGN_LEFT;
       canvas.saveState();
       ColumnText ct = new ColumnText(canvas);
       float lly = -1;
       float ury = 2;
       float llx;
       float urx;
       switch (alignment) {
           case Element.ALIGN_LEFT:
               llx = 0;
               urx = 20000;
               break;
           case Element.ALIGN_RIGHT:
               llx = -20000;
               urx = 0;
               break;
           default:
               llx = -20000;
               urx = 20000;
