Examples

Shows how to create a group of shapes, and print its contents using a document visitor.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// If you need to create "NonPrimitive" shapes, such as SingleCornerSnipped, TopCornersSnipped, DiagonalCornersSnipped,
// TopCornersOneRoundedOneSnipped, SingleCornerRounded, TopCornersRounded, DiagonalCornersRounded
// please use DocumentBuilder.InsertShape methods.
Shape balloon = new Shape(doc, ShapeType.Balloon)
{
    Width = 200,
    Height = 200,
    Stroke = { Color = Color.Red }
};

Shape cube = new Shape(doc, ShapeType.Cube)
{
    Width = 100,
    Height = 100,
    Stroke = { Color = Color.Blue }
};

GroupShape group = new GroupShape(doc);
group.AppendChild(balloon);
group.AppendChild(cube);

Assert.That(group.IsGroup, Is.True);

builder.InsertNode(group);

ShapeGroupPrinter printer = new ShapeGroupPrinter();
group.Accept(printer);

Console.WriteLine(printer.GetText());
