Visual TrueType Private Tables
TSI0
: Glyph Program Text Indices
TSI{0,1,2,3,5} are private tables used by Microsoft Visual TrueType (VTT) tool to store its hinting source data.
TSI0 is the index table containing the lengths and offsets for the glyph programs and ‘extra’ programs (‘fpgm’, ‘prep’, and ‘cvt’) that are contained in the TSI1 table.
TSI1
: Glyph Program Text UTF-8 Text Dump
TSI{0,1,2,3,5} are private tables used by Microsoft Visual TrueType (VTT) tool to store its hinting source data.
TSI1 contains the text of the glyph programs in the form of low-level assembly code, as well as the ‘extra’ programs ‘fpgm’, ‘ppgm’ (i.e. ‘prep’), and ‘cvt’.
TSI2
: VTT Talk Text Indices
TSI{0,1,2,3,5} are private tables used by Microsoft Visual TrueType (VTT) tool to store its hinting source data.
TSI2 is the index table containing the lengths and offsets for the glyph programs that are contained in the TSI3 table. It uses the same format as the TSI0 table.
TSI3
: VTT Talk UTF-8 Text Dump
TSI{0,1,2,3,5} are private tables used by Microsoft Visual TrueType (VTT) tool to store its hinting source data.
TSI3 contains the text of the glyph programs in the form of ‘VTTTalk’ code.
