The table directory beginning is indicated in the TTCHeader.No promotional/commercial activities. In case of multiple OpenType Fonts collection, For example, in case the font file has only one font, the table directory starts at the byte 0 of the file. Depending on the number of fonts in a file, the table directory may be located at different location in the file.

This directory is the top-level collection of the tables in the font file. (See Table Version Numbers.)ДЄn OTF file starts with a table directory. Packed 32-bit value with major and minor version numbers. 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.ДЄrray of four uint8s (length = 32 bits) used to identify a table, design-variation axis, script, language system, feature, or baseline Uint16 that describes a quantity in font design units.ДЎ6-bit signed fixed number with the low 14 bits of fraction (2.14).Дate and time represented in number of seconds since 12:00 midnight, January 1, 1904, UTC. Int16 that describes a quantity in font design units. OTF files use the following data types which are all in Big Endian. Data inside an OpenType font file is used for different purposes such as calculating the text layout, defining glyphs as TrueType or Compact Font Format (CFF) outlines, providing monochromatic or color bitmaps or SVG documents as alternate glyph descriptions, and meta-data information. Like TTF, it uses the same вЂsfntвЂ™ container structure and is compatible with the TrueType specifications. OTF specifications are available publicly by Microsoft and can be referred to from developerвЂ™s perspective. This new technology was introduced the same year with the name OpenType.

This resulted in combination of both underlying font formats to overcome the limitations and add new extensions. The modifications also included to introduce a more suitable font format that also meets the features of AdobeвЂ™s Type 1 (PostScript) font formats.ДЄdobe, in 1996, joined Microsoft in its efforts to supersede both AppleвЂ™s TrueType and its own Type 1 font formats. This didnвЂ™t go well and as a result, Microsoft started enhancing its owns TrueType font technology in 1994.

Microsoft attempted to license AppleвЂ™s advanced typography technology, known as GX Typography, in the early 1990вЂ™s. In addition, it was aimed to meet the requirements of complex behaviour of many of the worldвЂ™s writing systems. The requirement of OpenType fonts originated as a requirement for a more expressive font format that could handle fine typography.

The OpenType font format is supported by Mac OS X and Windows 2000 and later. This makes OTF format to accommodate majority writing systems and that is why it is uniformly used on major computer platforms. Developed by Microsoft and Adobe, OTF combines the features of PostScript and TrueType font formats. OTF font format is more scalable and extends the existing features of TTF formats for digital typography. otf extension refers to OpenType font format.
