To make a backplane visible you have to set the Visible property to true:

textStyle.BackplaneStyle.Visible = true;

textStyle.BackplaneStyle.Visible = True

The size of a backplane is determined by the object it is attached to. For example if a backplane is displayed behind a text its size depends on the text size. You can additionally inflate or deflate this size with the Inflate property of the NBackplaneStyle object. The following example creates a text style object and increases the backplane size:

Dim textStyle As NTextStyle = New NTextStyle()
textStyle.BackplaneStyle.Inflate = New NSizeL(10, 10) 'inflate by 10 points

NTextStyle textStyle = new NTextStyle();
textStyle.BackplaneStyle.Inflate = new NSizeL(10, 10); // inflate by 10 points

The shape of a backplane is controlled through the Shape property. It accepts values from the BackplaneShape enumeration. Use the following code to change the backplane shape:

backplane.Shape = BackplaneShape.Ellipse

backplane.Shape = BackplaneShape.Ellipse;

The supported backplane shapes are Rectangle, Circle, Ellipse, Cut Edge Rectangle and Smooth Edge Rectangle. In the case of Cut Edge Rectangle and Smooth Edge Rectangle you can specify the edge size in percent of the smaller backplane dimension (width or height). The size is specified with the EdgePercent property. Its default value is 20% and it can vary in the range [0, 50]:

backplane.Shape = BackplaneShape.CutEdgeRectangle
backplane.EdgePercent = 30 ' increase the cut edge size

backplane.Shape = BackplaneShape.CutEdgeRectangle;
backplane.EdgePercent = 30; // increase the cut edge size

The backplane has an attached NStandardFrameStyle object controlling the frame properties. When the backplane is not horizontal or vertical the frame properties are discarded and only a simple border can be displayed. The following table shows two labels with equal frame properties but different orientation:

Label with raised frame and border. Horizontal orientation.	Label with raised frame and border. Rotated 45 degrees.
