How to create shapes with complex geometry in Nevron Diagram?
In Nevron Diagram for .NET you can create custom shapes with complex geometry.
The following code example demonstrates how to create a rectangle with two wholes (a complex polygon):
[C#]
// Create a graphics path that represents the model of the polygon
GraphicsPath path =
new
GraphicsPath();
path.AddRectangle(
new
RectangleF(0, 0, 200, 200));
path.AddRectangle(
new
RectangleF(20, 20, 70, 160));
path.AddRectangle(
new
RectangleF(110, 20, 70, 160));
// Host the graphics path in a NCustomPath primitive
NCustomPath pathPrimitive =
new
NCustomPath(path, PathType.ClosedFigure);
// Create a composite shape and put the path primitive in it
NCompositeShape shape =
new
NCompositeShape();
shape.Primitives.AddChild(pathPrimitive);
// Add the composite shape to the drawing document's active layer
nDrawingDocument1.ActiveLayer.AddChild(shape);
// Update the model bounds
shape.UpdateModelBounds();
// Reposition the shape
shape.Location =
new
NPointF(50, 50);
[VB.NET]

Dim

New

path.AddRectangle(
New

path.AddRectangle(

path.AddRectangle(
New
RectangleF(110, 20, 70, 160))
' Host the graphics path in a NCustomPath primitive
Dim
pathPrimitive
As
New
NCustomPath(path, PathType.ClosedFigure)
' Create a composite shape and put the path primitive in it
Dim
shape
As
New
NCompositeShape()
shape.Primitives.AddChild(pathPrimitive)
' Add the composite shape to the drawing document's active layer
NDrawingDocument1.ActiveLayer.AddChild(shape)
' Update the model bounds
shape.UpdateModelBounds()
' Reposition the shape
shape.Location =
New
NPointF(50, 50)
