Note for font propeller heads - The VOLT source code table contains a serialized text presentation of your VOLT data, which is quite easy to understand. We don't want to encourage anyone to hack this data, but if you look at what's in there, you'll immediately figure the format out. The format is the same as that used to import and export lookups, glyph groups and glyph definitions described in the following section.
VOLT supports the import and export options shown in the composite screen capture shown below.
The glyph information is saved in as a .VTD file. A code snippet is shown below.
DEF_GLYPH "halfSha" ID 230 END_GLYPH DEF_GLYPH "halfSsa" ID 231 END_GLYPH DEF_GLYPH "halfSa" ID 232 END_GLYPH DEF_GLYPH "halfHa" ID 233 END_GLYPH DEF_GLYPH "halfKaSsa" ID 234 END_GLYPH DEF_GLYPH "halfJaNya" ID 235 END_GLYPH DEF_GLYPH "halfKaNukta" ID 236 END_GLYPH DEF_GLYPH "halfKhaNukta" ID 237 END_GLYPH Many font developers map glyphs to glyph ID in a standardized way. If you do this you only need name your glyphs once using the glyph editing tool and apply the exported .VTD file across your library.
Lookup information is saved in as a .VTL file. A code snippet is shown below.
DEF_LOOKUP "Nukta" PROCESS_BASE PROCESS_MARKS ALL DIRECTION LTR IN_CONTEXT END_CONTEXT AS_SUBSTITUTION SUB GROUP "FullForms" GLYPH "Nukta" WITH GROUP "FullNuktaForms" END_SUB END_SUBSTITUTION
Glyph group information is saved in as a .VTG file. A code snippet is shown below.
DEF_GROUP "FullJaForms"
ENUM GLYPH "fullJa"
GLYPH "fullJaNukta"
GLYPH "fullJaRa"
GLYPH "fullJaNuktaRa" END_ENUM
END_GROUP
This option is particularly useful if you need to add glyphs to a particular font using a tool that overwrites, deletes or corrupts OpenType layout tables or VOLT private tables.
Use the import options to reuse glyph, lookup, group and project information. The Import PostScript names option assigns the names stored in your font's POST table to the glyph names used by VOLT.

To save your work select 'Save Font' from the File menu or click the 'Save' button on the tool bar. VOLT saves its data into a temporary table inside the TTF. VOLT keeps more data around (to make its interface more user-friendly), so the translation to OT assembly is not reversible. As long as other tools preserve this table, there should not be a problem to open/save the same font in different tools.
