PDFSharp: Measuring height of long text with word wrap

PDFSharp supports automatic text wrapping when drawing long text portions:

textFormatter.DrawString(text, font, XBrushes.Black, new XRect(x, y, textAreaWidth, 1000), XStringFormats.TopLeft);

This will wrap the text if it is longer than textAreaWidth.

How can I get the height of the text that has just been drawn?

I tried it with gfx.MeasureString(), but there is no overload that supports specifying a maximal width. gfx.MeasureString() returns the size of the text without text wrapping.

Thanks for any hints.
