A newbie question. How to draw a horizontal line (same as <HR> in html)
in PDF using iText.


    Document document = new Document(PageSize.A4, 36, 36, 36, 36);
    PdfWriter writer = PdfWriter.getInstance(document, out);
    PdfContentByte cb = writer.getDirectContent();

    cb.setLineWidth(2.0f);     // Make a bit thicker than 1.0 default
    cb.setGrayStroke(0.95f); // 1 = black, 0 = white
    float x = 72f;
    float 7 = 72f;
    cb.moveTo(x,         y);
    cb.lineTo(x + 72f*6, y);
    cb.stroke();


That's a good example.
A follow-up question could be: how do I know the value of y?
There are different possibilities.
PdfWriter has a method getVerticalPosition,
but I like to use page events to draw lines,
for instance using onParagraph or onGenericTag.

On a related note if you know how to do a relative lineTo in iText I would like to know, maybe PDF doesn't allow it ? 

See table 4.9 on page 196-197 of the PDF Reference manual
for a list with the 'path construction operators'.
There is no relative lineTo...
