iTextSharp watermark multiline text - itext

Question

I have seen answers to question of how to add text watermark to an existing PDF document using iTextSharp. My question is how can we do multiline text. Is there a way to do this without having multiple PdfContentByte defined. I have tried to insert a newline character with no luck.
Here is the code from the internet. I just added
pdfData.ShowTextAligned(Element.ALIGN_CENTER, editDate, (pageRectangle.Width / 2) + 100, (pageRectangle.Height / 2) - 100, 45);
as the second line to get the second line of the watermark, it works but uses same parameters (color, size, etc.) as the first.
iTextSharp.text.Rectangle pageRectangle = PDFreader.GetPageSizeWithRotation(1);
//pdfcontentbyte object contains graphics and text content of page returned by pdfstamper
PdfContentByte pdfData = stamper.GetOverContent(1);
//create fontsize for watermark
pdfData.SetFontAndSize(BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED), 120);
//create new graphics state and assign opacity
PdfGState graphicsState = new PdfGState();
graphicsState.FillOpacity = 0.2F;
//set graphics state to pdfcontentbyte
pdfData.SetGState(graphicsState);
//set color of watermark
pdfData.SetColorFill(iTextSharp.text.Color.BLUE);
//indicates start of writing of text
pdfData.BeginText();
//show text as per position and rotation
pdfData.ShowTextAligned(Element.ALIGN_CENTER, "E D I T E D" , (pageRectangle.Width / 2), (pageRectangle.Height / 2), 45);
pdfData.ShowTextAligned(Element.ALIGN_CENTER, editDate, (pageRectangle.Width / 2) + 100, (pageRectangle.Height / 2) - 100, 45);
//call endText to invalid font set
pdfData.EndText();
