Oh dear! - There's an example of this in the Nevron Example app.
The code needs to look something like:...
var txt = "Here is some text to measure";
double targetWidth = 150;
var settings = new NPaintTextRectSettings ();
settings.SingleLine = false;
settings.WrapMode = ENTextWrapMode.WordWrap;
settings.HorzAlign = ENTextHorzAlign.Left;
settings.VertAlign = ENTextVertAlign.Top;
var resolution = canvas.Ownerdocument.GetEffectiveResolution ();
var font = new NFont (NFontDescriptor.DefaultMonoFamilyName, 10);
var textSize = font.MeasureString (txt.ToCharArray (), resolution, 150, false, ref settings);
arg.PaintVisitor.SetFill (NColor.Black);
arg.PaintVisitor.SetFont (font);
arg.PaintVisitor.PaintString (
new NRectangle(35, 35, textSize.Width, textSize.Height),
txt, ref settings);

I found NFont.MeasureText but this requires that the font object be attached/associated with a document. I'm rendering text to the canvas in PrePaint using arg.PaintVisitor.PaintString and need a way to calculate the required height given a specific width.
