In spite of this fact, the font format has considerably wider language support possibilities, because it contains numerous character sets. Besides, it can be installed on the same operating system together with PostScript Type 1 and TrueType fonts.Ī significant advantage of OTF fonts is that all its data is included into a single file.

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.)Īn OTF file starts with a table directory. Packed 32-bit value with major and minor version numbers.

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 ‘sfnt’ container structure and is compatible with the TrueType specifications. OTF specifications are available publicly by Microsoft and can be referred to from developer’s perspective. This new technology was introduced the same year with the name OpenType.

Microsoft attempted to license Apple’s advanced typography technology, known as GX Typography, in the early 1990’s. In addition, it was aimed to meet the requirements of complex behaviour of many of the world’s writing systems.

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.
