    NestedShapeCollection.AddLine(PointF, PointF) Method

    Adds a line to a shape group or a drawing canvas.

    Namespace: DevExpress.XtraRichEdit.API.Native

    Assembly: DevExpress.RichEdit.v25.1.Core.dll

    NuGet Package: DevExpress.RichEdit.Core

    #Declaration

    NestedShape AddLine(
        PointF start,
        PointF end
    )

    #Parameters

    Name Type Description
    start PointF

    An object that specifies x- and y-coordinates of the start point relative to the top left corner of the parent object. The Document.Unit property defines the measurement units.

    end PointF

    An object that specifies x- and y-coordinates of the end point relative to the top left corner of the parent object. The Document.Unit property defines the measurement units.

    #Returns

    Type Description
    NestedShape

    The shape in the group or drawing canvas.

    #Remarks

    #Add a Line to a Drawing Canvas

    Call the ShapeCollection.InsertCanvas method to add a drawing canvas to a document. Use the Shape.CanvasItems property to access the collection of canvas items. The collection’s Add methods allow you to add shapes and pictures to the canvas.

    Use the Shape.Line property to access a ShapeLine object that allows you to specify line settings.

    The example below creates a drawing canvas with three shapes.

    Add a line to a canvas

    Document document = wordProcessor.Document;
    // Set the measurement unit to inches.
    document.Unit = DevExpress.Office.DocumentUnit.Inch;
    // Insert a drawing canvas.
    Shape canvas = document.Shapes.InsertCanvas(document.Range.Start, new RectangleF(1.5f, 1f, 6f, 1.5f));
    // Access the collection of canvas items. 
    var canvasItems = canvas.CanvasItems;
    // Add a rectangle to the canvas.
    var shape1 = canvasItems.AddShape(ShapeGeometryPreset.Rectangle, new RectangleF(0f, 0f, 2f, 1.5f));
    shape1.Fill.SetSolidFill(Color.FromArgb(0xA4, 0xFF, 0xFF));
    shape1.Line.Color = Color.DarkGray;
    shape1.Line.Thickness = 2;
    // Add a line to the canvas.
    var shape2 = canvasItems.AddLine(new PointF(2.1f, 0.8f), new PointF(3.7f, 0.8f));
    ShapeLine lineFormat = shape2.Line;
    // Specify the line color.
    lineFormat.Color = Color.FromArgb(0xA1, 0xF9, 0xA1);
    // Set the line width.
    lineFormat.Thickness = 8;
    // Add an arrowhead to the line end.
    lineFormat.EndArrowType = LineArrowType.StealthArrow;
    lineFormat.EndArrowWidth = LineArrowSize.Large;
    lineFormat.EndArrowLength = LineArrowSize.Large;
    // Add a parallelogram to the canvas.
    var shape3 = canvasItems.AddShape(ShapeGeometryPreset.Parallelogram, new RectangleF(3.8f, 0f, 2f, 1.5f));
    shape3.Fill.SetSolidFill(Color.FromArgb(0xFF, 0xA5, 0xA5));
    shape3.Line.Color = Color.DarkGray;
    shape3.Line.Thickness = 2;
    

    #Add a Line to a Shape Group

    Call the ShapeCollection.InsertGroup method to create a shape group. The Shape.GroupItems property returns the collection of group items. Use the collection’s Add methods to add shapes and pictures to the group.

    Use the Shape.Line property to access a ShapeLine object that allows you to specify line settings.

    The example below creates a shape group in the document.

    Add a line to shape group

    Document document = wordProcessor.Document;
    // Set the measurement unit to inches.
    document.Unit = DevExpress.Office.DocumentUnit.Inch;
    // Insert a shape group.
    Shape group = document.Shapes.InsertGroup(document.Range.Start);
    // Specify the group position relative to the left and top edges of the page. 
    group.Offset = new PointF(1.5f, 1f);
    // Access the collection of group items. 
    var groupItems = group.GroupItems;
    // Add a rectangle to the group.
    var shape1 = groupItems.AddShape(ShapeGeometryPreset.Rectangle, new RectangleF(0f, 0f, 2f, 1.5f));
    shape1.Fill.SetSolidFill(Color.FromArgb(0xA4, 0xFF, 0xFF));
    shape1.Line.Color = Color.DarkGray;
    shape1.Line.Thickness = 2;
    // Add a line to the group.
    var shape2 = groupItems.AddLine(new PointF(2.1f, 0.8f), new PointF(3.7f, 0.8f));
    ShapeLine lineFormat = shape2.Line;
    // Specify the line color.
    lineFormat.Color = Color.FromArgb(0xA1, 0xF9, 0xA1);
    // Set the line width.
    lineFormat.Thickness = 8;
    // Add an arrowhead to the line end.
    lineFormat.EndArrowType = LineArrowType.StealthArrow;
    lineFormat.EndArrowWidth = LineArrowSize.Large;
    lineFormat.EndArrowLength = LineArrowSize.Large;
    // Add a parallelogram to the group.
    var shape3 = groupItems.AddShape(ShapeGeometryPreset.Parallelogram, new RectangleF(3.8f, 0f, 2f, 1.5f));
    shape3.Fill.SetSolidFill(Color.FromArgb(0xFF, 0xA5, 0xA5));
    shape3.Line.Color = Color.DarkGray;
    shape3.Line.Thickness = 2;
