	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();


Maybe you want to replace "72f*6" with "PageSize.A4.getWidth() - 72.0" 
as the above example only gives you a 1 inch horizontal line, set one 
inch up from origin (south-west corner).


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 ?  But in the direct 
PostScript I am porting from it would go like this:

/hrline {
	gsave

	translate

	2 setlinewidth
	0.95 setgray

	0 0 moveto
	72 6 mul 0 rlineto  %% rlineto here in iText ?
	stroke

	grestore
} def

72 72 hrline
