Examples

// Create a swimlane background
var swimlane = new RectangleElement("swimlane-1")
{
    Position = new Point(0, 0),
    Width = 300,
    Height = 600,
    Fill = "#ecf0f1",
    Stroke = "#bdc3c7",
    StrokeWidth = 2,
    CornerRadius = 4,
    Label = "Development"
};

Remarks

Rectangles are one of the most common shape elements, useful for: - Swimlanes in process diagrams - Containers/groups without the node behavior - Annotations and labels - Background regions

Constructors

public double CornerRadius { get; set; }

Property Value

double

Type

Gets the type identifier for this element.

public override string Type { get; }

Remarks

Used by renderer registries to select the appropriate renderer. For nodes, this typically comes from the node definition's Type property. For shapes, this identifies the shape type (line, rectangle, text, etc.).
