NAME
       PDF::API2::Basic::TTF::OS_2 - the OS/2 table in a TTF font

DESCRIPTION
       The OS/2 table has two versions and forms, one an extension of the other. This module
       supports both forms and the switching between them.

INSTANCE VARIABLES
       No other variables than those in table and those in the standard:

           Version

           usWeightClass

           bMidline
           bXheight
           ulUnicodeRange1
           ulUnicodeRange2
           ulUnicodeRange3
           ulUnicodeRange4
           achVendID
           fsSelection
           usFirstCharIndex
           usLastCharIndex
           sTypoAscender
           sTypoDescender
           sTypoLineGap
           usWinAscent
           usWinDescent
           ulCodePageRange1
           ulCodePageRange2
           xHeight
           CapHeight
           defaultChar
           breakChar
           maxLookups

       Notice that versions 0, 1 & 2 of the table are supported. Notice also that the Panose
       variable has been broken down into its elements.

METHODS
       $t->read

       Reads in the various values from disk (see details of OS/2 table)

       $t->out($fh)

       Writes the table to a file either from memory or by copying.

       $t->XML_element($context, $depth, $key, $value)

       Tidies up the hex values to output them in hex

       $t->XML_end($context, $tag, %attrs)

       Now handle them on the way back in

       $t->update

       Updates the OS/2 table by getting information from other sources:

       Updates the "firstChar" and "lastChar" values based on the MS table in the cmap.

       Updates the sTypoAscender, sTypoDescender & sTypoLineGap to be the same values as
       Ascender, Descender and Linegap from the hhea table (assuming it is dirty) and also sets
       usWinAscent to be the sum of Ascender+Linegap and usWinDescent to be the negative of
       Descender.

BUGS
       None known
