convertToTwips
float convertToTwips(java.lang.String foValue) throws FOPException
convert given value to RTF units- Parameters:
foValue
- a value like "12mm" TODO: tested with "mm" units only, needs work to comply with FO spec Why does it search for period instead of simply breaking last two Characters into another units string? - Chris- Throws:
FOPException
-
