![]() Examples of 2.14 values are: Decimal Value To compute the actual value, take the integer and add the fraction. The F2DOT14 format consists of a signed, 2’s complement integer and an unsigned fraction. Long offset to a table, same as uint32, NULL offset = 0x00000000 Short offset to a table, same as uint16, NULL offset = 0x0000 The value is represented as a signed 64-bit integer.Īrray of four uint8s (length = 32 bits) used to identify a script, language system, feature, or baseline ![]() Uint16 that describes a quantity in font design units.ġ6-bit signed fixed number with the low 14 bits of fraction (2.14).ĭate represented in number of seconds since 12:00 midnight, January 1, 1904. Int16 that describes a quantity in font design units. All OpenType fonts use Motorola-style byte ordering (Big Endian): Data Type ![]() The following data types are used in the OpenType font file. Collection fonts that use CFF or CFF2 outlines should have an. TTC extension, regarless of whether layout tables are present or not. Collection fonts that use TrueType outlines should have a.TTF, depending on the desire for backward compatibility on older systems or with previous versions of the font. Fonts containing TrueType outlines may have either.In all cases, fonts with only CFF data (no TrueType outlines) always have an.TTF, depending on the kind of outlines in the font and the creator’s desire for compatibility on systems without native OpenType support. Some of this supporting data is used no matter which outline format is used some of the supporting data is specific to either TrueType or PostScript. Rasterizers use combinations of data from the tables contained in the font to render the TrueType or PostScript glyph outlines. An OpenType font file contains data, in table format, that comprises either a TrueType or a Compact Font Format (CFF) outline font.
