Pdf Graphic Elements

Select.Pdf has support to draw a variety of shapes, such as:

These graphic elements (all derived from PdfElement), share a number of properties that can be used to modify their appearance:

  • Line style: LineStyle can be used to specify the line styles of the graphic elements that draw lines. Using this, the line width, line dash style, line cap style and line join style can be specified.

  • Gradient: Gradient can be used to specify the gradient used to fill a shape.

  • Line color: ForeColor can be used to specify the color of the drawn lines.

  • Background color: BackColor can be used to specify the background color.

Sample Code

The following code shows how to draw several graphic elements:

// create a new pdf document
PdfDocument doc = new PdfDocument();

// add a new page to the document
PdfPage page = doc.AddPage();

// define a rendering result object
PdfRenderingResult result;

// simple horizontal line element
PdfLineElement line1 = new PdfLineElement(0, 0, 400, 0);
line1.LineStyle.LineWidth = 3;
result = page.Add(line1);

// horizontal dotted red line element
PdfLineElement line2 = new PdfLineElement(0, 30, 400, 30);
line2.ForeColor = System.Drawing.Color.Red;
line2.LineStyle.LineWidth = 2;
line2.LineStyle.LineDashStyle = PdfLineDashStyle.Dot;
result = page.Add(line2);

// horizontal dashed blue line element with complex styles
PdfLineElement line3 = new PdfLineElement(0, 60, 400, 60);
line3.ForeColor = System.Drawing.Color.Blue;
line3.LineStyle.LineWidth = 2;
line3.LineStyle.LineDashStyle = PdfLineDashStyle.Dash;
line3.LineStyle.LineCapStyle = PdfLineCapStyle.RoundCap;
line3.LineStyle.LineJoinStyle = PdfLineJoinStyle.RoundJoin;
result = page.Add(line3);

// simple rectangle
PdfRectangleElement rect1 = new PdfRectangleElement(0, 90, 400, 100);
result = page.Add(rect1);

// simple circle
PdfCircleElement circ1 = new PdfCircleElement(50, 250, 50);
circ1.ForeColor = System.Drawing.Color.Green;
result = page.Add(circ1);

// ellipse filled with gradient background color
PdfEllipseElement elli1 = new PdfEllipseElement(300, 250, 100, 50);
elli1.ForeColor = System.Drawing.Color.Brown;
elli1.Gradient = new PdfGradient(PdfGradientDirection.ForwardDiagonal, 
    System.Drawing.Color.LightBlue, System.Drawing.Color.DarkBlue);
elli1.LineStyle.LineWidth = 2;
result = page.Add(elli1);

// bezier curve
PdfBezierCurveElement bez1 = new PdfBezierCurveElement(
    50, 350, 100, 400, 200, 350, 250, 370);
result = page.Add(bez1);

// save pdf document
doc.Save(Response, false, "Sample.pdf");

// close pdf document
doc.Close();
