Problem in newline text.

When I use this code I expect a multiline text:

VB

using (XGraphics gfx = XGraphics.FromPdfPage(page))
{
   string text = "aaa\r\nbbb\ncccc";
   gfx.DrawString(text, font, XBrushes.Black, 20, 20);
}

In fact, when I draw in a winform using GDI+ this text renders in multiple lines. Is there a way to achieve this with PDF Sharp?

The XGraphics.DrawString(...) method does not handle line breaks (newlines) as the .NET Graphics.DrawString(…) method does.
Instead, PDFSharp will output something like blanks for \r and \n.

This is a little bit trickier to work around. You need an XTextFormatter, a XRect for the region which is available for the layouter and then call DrawString(…) on the formatter instead of the XGraphics object:

VB

var formatter = new XTextFormatter(pageGraphics);
var layoutRectangle = new XRect(10, 10, page.Width, page.Height);
formatter.DrawString("Hello\r\nWorld", arial, XBrushes.Black, layoutRectangle);
