Post subject:  DrawString for a text with \n
Hello all,
I noticed there were some discussions on this in the past. How to display a text with line breaks,
for example "1\n2\n3\n4\n5", but did not find an answer. Is this possible at all in PDFSharp?
Thanks.

Hi!
Use XTextFormatter class (and don't forget the '\n' in your strings).

Dear Thomas,
Thank you for the quick response. I actually saw a sample of XTextFormatter and tried it. Here is the part of the code with hard coded values:
..................
PdfDocument s_document = new PdfDocument();
PdfPage page = new PdfPage();
page = s_document.AddPage();
XGraphics gfx = XGraphics.FromPdfPage(page);
XStringFormat drawFormat = new XStringFormat();
drawFormat = XStringFormats.TopLeft;
XFont font = new XFont(node.Font.Name, node.Font.Size);
XTextFormatter tf = new XTextFormatter(gfx);
XRect rect = new XRect(62, 666, 449, 114);
Node.Text = "1\n2\n3\n4\n5\n6\n7\n8";
gfx.DrawString(node.Text, font, XBrushes.Black, rect, drawFormat);
.......................
The output comes in a rectangle as
1 2 3 4 5 6 7 8

So it seems that the \n is converted to tab or several spaces.

Sorry, I forgot the Frawrectangle statement. Here is the corrected code again

PdfDocument s_document = new PdfDocument();
PdfPage page = new PdfPage();
page = s_document.AddPage();
XGraphics gfx = XGraphics.FromPdfPage(page);
XStringFormat drawFormat = new XStringFormat();
drawFormat = XStringFormats.TopLeft;
XFont font = new XFont(node.Font.Name, node.Font.Size);
XTextFormatter tf = new XTextFormatter(gfx);
XRect rect = new XRect(62, 666, 449, 114);
gfx.DrawRectangle(XBrushes.LightYellow, rect);
node.Text = "1\n2\n3\n4\n5\n6\n7\n8";
gfx.DrawString(node.Text, font, XBrushes.Black, rect, drawFormat);

Problem sloved, thanks Thomas.

I had a mistake, I used
gfx.DrawString(node.Text, font, XBrushes.Black, rect, drawFormat);
instead of using the text formatter
tf.DrawString(node.Text, font, XBrushes.Black, rect, drawFormat);

Thank you very much for the assistance.
