    What is a TTF file?

    A file with .ttf extension represents font files based on the TrueType specifications font technology. It was initially designed and launched by Apple Computer, Inc for Mac OS and was later adopted by Microsoft for Windows OS. TrueType fonts provide highest quality display on computer screens and printers without any dependency on resolution. All modern applications using fonts are able to work with TTF files. TTF font files are freely available over the internet and can also be converted to other font file formats such as OTF and WOFF.

    Brief History

    Designed by Apply Computer, Inc in 1980s for MacOS, the TTF font format was aimed at resolving some technical limitations by Adobe’s Type 1 format. Apple included support for TrueType fonts in Mac in 1991. The design objective behind TTF fonts was efficiency in storage and processing, and extensibility. Based on this extensibility, existing fonts can be converted to TrueType format.

    Microsoft first used the TrueType fonts in Windows 3.1 in April 1992 after Apple agreed to license TrueType to Microsoft. It improved the rasterization mechanism, and improved its efficiency and performance.

    True Type File Format Specifications

    A TrueType font file is a binary file that consists of a sequence of concatenated tables. Each table is a sequence of words and has a name known as Tag. Each tag is of uint32 data type and consists of four characters. The first table in the file is font directory that gives access to other tables in the font file. Font data is contained in other tables followed after the font directory table. Since each table is accessible by its tag, the tables can appear in any order in the file.

    The required tables and their tag names are shown in the following table.

    TagTable
    ‘cmap’character to glyph mapping
    ‘glyf’glyph data
    ‘head’font header
    ‘hhea’horizontal header
    ‘hmtx’horizontal metrics
    ’loca'index to location
    ‘maxp’maximum profile
    ’name'naming
    ‘post’PostScript

    Data Types

    TrueType fonts use the standard integer and additional data types as listed in the following table.

    Data TypeDescription
    shortFrac16-bit signed fraction
    Fixed16.16-bit signed fixed-point number
    FWord16-bit signed integer that describes a quantity in FUnits, the smallest measurable distance in em space.
    uFWord16-bit unsigned integer that describes a quantity in FUnits, the smallest measurable distance in em space.
    F2Dot1416-bit signed fixed number with the low 14 bits representing fraction.
    longDateTimeThe long internal format of a date in seconds since 12:00 midnight, January 1, 1904. It is represented as a signed 64-bit integer.

    Font Directory

    The first table in the TrueType font is the font directory that provides access to the information required for accessing data in other tables. It further consists of:

    • Offset subtable - keeps record of the tables in the font and provides offset information to access each table in the directory
    • Table Directory - Contains entries for each table in the font

    Offset SubTable

    The offset subtable is shown below.

    TypeNameDescription
    uint32scaler typeA tag to indicate the OFA scaler to be used to rasterize this font; see the note on the scaler type below for more information.
    uint16numTablesnumber of tables
    uint16searchRange(maximum power of 2 <= numTables)*16
    uint16entrySelectorlog2(maximum power of 2 <= numTables)
    uint16rangeShiftnumTables*16-searchRange

    Table directory

    The table directory comes right after the offset subtable. Its structure is as shown in the following table.

    TypeNameDescription
    uint32tag4-byte identifier
    uint32checkSumchecksum for this table
    uint32offsetoffset from beginning of sfnt
    uint32lengthlength of this table in byte (actual length not padded length)

    Each table in a font file must have its own table directory entry. Entries in a table must be sorted in ascending order by tag.

    What is truetype font?

    A TrueType font (TTF) is a font format developed by Apple and Microsoft. It uses scalable vector graphics to display text at any size without losing quality. TrueType fonts are widely supported across various operating systems and applications, making them a standard for digital typography.

    what are ttf fonts?

    TrueType Fonts (TTF) are a type of font format that was developed by Apple in the late 1980s and later adopted by Microsoft in the early 1990s. They are used to display text on digital screens and printers, offering a scalable and high-quality alternative to older bitmap-based fonts. The format became widely adopted and remains one of the most popular font formats in use today.
