This sample shows how to render graphics in both a preview and a PDF document.

PDF Output File

See the PDF file created by this sample: output.pdf (61 kB)

Screen Shots

Here are the sample screen shots (application window (left) and PDF file (right)):

Screen shot of the application window Screen shot of the PDF output

The left screen shot shows a placeholder for the embedded PDF document because Windows cannot render PDF.

Source Code

This is the source code of the Render method that is called for screen, PDF, and printer output:
XRect rect;
XPen pen;
double x = 50, y = 100;
XFont fontH1 = new XFont("Times", 18, XFontStyle.Bold);
XFont font = new XFont("Times", 12);
XFont fontItalic = new XFont("Times", 12, XFontStyle.BoldItalic);
double ls = font.GetHeight(gfx);
 
// Draw some text
gfx.DrawString("Create PDF on the fly with PDFsharp",
    fontH1, XBrushes.Black, x, x);
gfx.DrawString("With PDFsharp you can use the same code to draw graphic, " +
    "text and images on different targets.", font, XBrushes.Black, x, y);
y += ls;
gfx.DrawString("The object used for drawing is the XGraphics object.", 
    font, XBrushes.Black, x, y);
y += 2 * ls;
 
// Draw an arc
pen = new XPen(XColors.Red, 4);
pen.DashStyle = XDashStyle.Dash;
gfx.DrawArc(pen, x + 20, y, 100, 60, 150, 120);
 
// Draw a star
XGraphicsState gs = gfx.Save();
gfx.TranslateTransform(x + 140, y + 30);
for (int idx = 0; idx < 360; idx += 10)
{
  gfx.RotateTransform(10);
  gfx.DrawLine(XPens.DarkGreen, 0, 0, 30, 0);
}
gfx.Restore(gs);
 
// Draw a rounded rectangle
rect = new XRect(x + 230, y, 100, 60);
pen = new XPen(XColors.DarkBlue, 2.5);
XColor color1 = XColor.FromKnownColor(KnownColor.DarkBlue);
XColor color2 = XColors.Red;
XLinearGradientBrush lbrush = new XLinearGradientBrush(rect, color1, color2, 
  XLinearGradientMode.Vertical);
gfx.DrawRoundedRectangle(pen, lbrush, rect, new XSize(10, 10));
 
// Draw a pie
pen = new XPen(XColors.DarkOrange, 1.5);
pen.DashStyle = XDashStyle.Dot;
gfx.DrawPie(pen, XBrushes.Blue, x + 360, y, 100, 60, -130, 135);
 
// Draw some more text
y += 60 + 2 * ls;
gfx.DrawString("With XGraphics you can draw on a PDF page as well as " +
    "on any System.Drawing.Graphics object.", font, XBrushes.Black, x, y);
y += ls * 1.1;
gfx.DrawString("Use the same code to", font, XBrushes.Black, x, y);
x += 10;
y += ls * 1.1;
gfx.DrawString("• draw on a newly created PDF page", font, XBrushes.Black, x, y);
y += ls;
gfx.DrawString("• draw above or beneath of the content of an existing PDF page", 
    font, XBrushes.Black, x, y);
y += ls;
gfx.DrawString("• draw in a window", font, XBrushes.Black, x, y);
y += ls;
gfx.DrawString("• draw on a printer", font, XBrushes.Black, x, y);
y += ls;
gfx.DrawString("• draw in a bitmap image", font, XBrushes.Black, x, y);
x -= 10;
y += ls * 1.1;
gfx.DrawString("You can also import an existing PDF page and use it like " +
    "an image, e.g. draw it on another PDF page.", font, XBrushes.Black, x, y);
y += ls * 1.1 * 2;
gfx.DrawString("Imported PDF pages are neither drawn nor printed; create a " + 
    "PDF file to see or print them!", fontItalic, XBrushes.Firebrick, x, y);
y += ls * 1.1;
gfx.DrawString("Below this text is a PDF form that will be visible when " + 
    "viewed or printed with a PDF viewer.", fontItalic, XBrushes.Firebrick, x, y);
y += ls * 1.1;
XGraphicsState state = gfx.Save();
XRect rcImage = new XRect(100, y, 100, 100 * Math.Sqrt(2));
gfx.DrawRectangle(XBrushes.Snow, rcImage);
gfx.DrawImage(XPdfForm.FromFile("../../../../../PDFs/SomeLayout.pdf"), rcImage);
gfx.Restore(state);
