Method Detail

parseFormatStr

public static double[] parseFormatStr(java.lang.String s)
                               throws java.text.ParseException

parse position strings like "100%-5em+4pt" into npos, emoffset, pt_offset. Note px is acceptable, but pt is proper. Ems are rounded to the nearest hundredth. Percents are returned as normal (0-1) and rounded to the nearest thousandth.

Throws:

java.text.ParseException

Throws:

java.text.ParseException

formatLayoutStr
