In the Nevron Graphics lengths are specified as NLength structures. The NLength structure groups together a value and a measurement unit. The following example creates a length that represents ten pixels:

NLength tenPixels = new NLength(10, NGraphicsUnit.Pixel);

Dim tenPixels As New NLength(10, NGraphicsUnit.Pixel)

If you do not specify a measurement unit then the length will by default use the NGraphics.Point measurement unit.

NLength tenPoints = new NLength(10);

Dim tenPoints As NLength = New NLength(10)

In the Nevron Graphics sizes measured in arbitrary measurement units are specified as NSizeL structures. The NSizeL structure groups together two NLength structures - one for the Width and one for the Height. The following example creates a size, which is ten pixels wide and 2 points high:

NSizeL size = new NSizeL(new NLength(10, NGraphicsUnit.Pixel), new NLength(2, NGraphicsUnit.Point));

Dim size As NSizeL = New NSizeL(New NLength(10, NGraphicsUnit.Pixel), New NLength(2, NGraphicsUnit.Point))

In Nevron Graphics points measured in arbitrary measurement units are specified as NPointL structures. The NPointL structure groups together two NLength structures - one for the X and one for the Y value of the point. The following example creates a point that represents a coordinate at [10px, 2pt]:

NPointL point = new NPointL(new NLength(10, NGraphicsUnit.Pixel), new NLength(2, NGraphicsUnit.Point));

Dim point As New NPointL(New NLength(10, NGraphicsUnit.Pixel), New NLength(2, NGraphicsUnit.Point))

In Nevron Graphics margins measured in arbitrary measurement units are specified as NMarginsL structures. The NMarginsL structure groups together four NLength structures corresponding to the Left, Top, Right and Bottom margin. The following example creates a margin that represents margins of ten pixels for the Left, Top, Right and Bottom:

NMarginsL margins = new NMarginsL(new NLength(10, NGraphicsUnit.Pixel), new NLength(10, NGraphicsUnit.Pixel), new NLength(10, NGraphicsUnit.Pixel),  new NLength(10, NGraphicsUnit.Pixel));

Dim margins As New NMarginsL(New NLength(10, NGraphicsUnit.Pixel), New NLength(10, NGraphicsUnit.Pixel), New NLength(10, NGraphicsUnit.Pixel), New NLength(10, NGraphicsUnit.Pixel))
