            PdfStringFormat format = new PdfStringFormat();
            format.LineSpacing = 20f;
            float pageWidth = page.Canvas.ClientSize.Width;
            PdfBrush brush = PdfBrushes.DarkBlue;
            float y = 30;
            PdfStringLayouter textLayouter = new PdfStringLayouter();
            PdfStringLayoutResult result
                = textLayouter.Layout(text, font, format, new SizeF(pageWidth, 0));
            foreach (LineInfo line in result.Lines)
            {
                page.Canvas.DrawString(line.Text, font, brush, 0, y, format);
                y = y + result.LineHeight;
            }

Dim page As PdfPageBase = section.Pages.Add()
	Dim font As New PdfFont(PdfFontFamily.Helvetica, 11)
	Dim format As New PdfStringFormat()
	format.LineSpacing = 20F
	Dim pageWidth As Single = page.Canvas.ClientSize.Width
	Dim brush As PdfBrush = PdfBrushes.DarkBlue
	Dim y As Single = 30
	Dim textLayouter As New PdfStringLayouter()
	Dim result As PdfStringLayoutResult = textLayouter.Layout(text, font, format, New SizeF(pageWidth, 0))

	For Each line As LineInfo In result.Lines
		page.Canvas.DrawString(line.Text, font, brush, 0, y, format)
		y = y + result.LineHeight
	Next

Now that is all the core codes for draw text in PDF.  Apart from converting text to PDF, Spire.PDF for WPF also can extract PDF text.
