thai2volt - Create VOLT code for standard Thai fonts
THAI2VOLT [-a angle] [-c] [-k flags] [-x file] infile outfile Copies the input font to the output font adding various tables on the way. If the font is not already a Unicode font, it will be converted to one.
-a angle Sets italic angle -c Don't add circle glyph (U+25CC) if one not present. Adding a circle glyph destroys the hmdx, VDMX & LTSH tables. -k Add empty kerning tables to VOLT table. Bitfield of tables 0 - ai moving left over consonants 1 - wide upper diacritics moving base right following tall things -x XML point database file for infile -z Don't add zwsp (U+200B) if not present
This program does a number of things:
It creates a dotted circle glyph if one is not present and adds it to the font. And also a blank ZWSP (U+200B) glyph if not present.
It reencodes the font to conform to Unicode encoding appropriate to OpenType fonts and also to Win95 Thai editions
It creates attachment points for each glyph
It adds kerning rules to ensure glyphs don't clash.
Since positioning is dependent on italic angle. If thai2gdl is used on an italic font the slope of the font should be given to the program if it is not already specified in the POST table in the font.
