If you want to draw simple and fixed shapes (like: lines, rectangle, ellipse, etc.) using .NET WinForms classes, you can try using the System.Drawing.Graphics class with methods like DrawRectangle, DrawPolygon, DrawLines, etc. You can find more details here: https://docs.microsoft.com/en-us/dotnet/api/system.drawing.graphics?view=netframework-4.7.2 However, if you are looking for more advanced shapes including measuring specialized objects (like Ruler, Poly-Rulers, Rectangle, Text, Highlight, etc.) that can be edited by user dynamically at runtime, you can try the Annotations objects and functions from LEADTOOLS .NET SDK. Note that these objects are drawn on a different layer over the image. Also they can be realized to the image to become part of the its' pixel data. For example, the following code shows how you can create a line and Ruler .NET objects at runtime: // assumes _automation is valid // Create Line object AnnPolylineObject polyline = new AnnPolylineObject(); polyline.Points.Add(container.Mapper.PointToContainerCoordinates( new LeadPointD(100, 100))); polyline.Points.Add(container.Mapper.PointToContainerCoordinates( new LeadPointD(300, 100))); polyline.Stroke = AnnStroke.Create(AnnSolidColorBrush.Create( "blue" ), LeadLengthD.Create(2.0)); _automation.Container.Children.Add(polyline); //Create Ruler object double inch = 720.0; AnnPolyRulerObject polyRulerObj = new AnnPolyRulerObject(); polyRulerObj.Points.Add(LeadPointD.Create(1 * inch, 1 * inch)); polyRulerObj.Points.Add(LeadPointD.Create(2 * inch, 2 * inch)); polyRulerObj.Points.Add(LeadPointD.Create(1 * inch, 5 * inch)); // Set the stroke polyRulerObj.Stroke = AnnStroke.Create(AnnSolidColorBrush.Create( "Red" ), LeadLengthD.Create(2)); // Add the object to the automation container _automation.Container.Children.Add(polyRulerObj); More details can be found here: https://www.leadtools.com/help/leadtools/v20/dh/to/implementing-annotations.html
