The function measures the height of a formatted text block.
Before calling this function a font (see DynaPDF.SetFont) and the output rectangle must be set with the function DynaPDF.SetTextRect. The parameter Height of DynaPDF.SetTextRect should be set to -1 to avoid page breaks. Otherwise the height of the first text block is returned that fits into the given height of the rectangle.
The parameter AText must contain the same text (incl. format tags if any) as which should be printed later with DynaPDF.WriteFText.
