| Description | .ttf (TrueType Font) The .ttf format stands for TrueType Font, a standard font format developed by Apple and Microsoft in the late 1980s. TrueType fonts are scalable fonts that render cleanly at any size, making them ideal for both screen and print use. They contain both the screen and printer font data in a single component, simplifying font management and usage. TTF files are widely supported on both Windows and macOS systems and are commonly used for text rendering in digital environments. |
| Technical details | The `.ttf` (TrueType Font) format is a standard font file format with the following characteristics: - **Font Outlines**: Utilizes quadratic Bézier curves for font outlines, differing from PostScript's cubic curves, simplifying grid fitting. - **Scalability**: Can be resized to any size without loss of quality, essential for various display environments. - **Hinting**: Includes hinting to align font outlines with pixel grids at small sizes, enhancing legibility on low-resolution screens. - **Character Encoding**: Supports multiple encoding schemes, including Unicode, for a wide range of characters and symbols. - **Glyph Representation**: Characters are depicted by glyphs defined by points outlining their shape. - **Embedding Permissions**: Contains permissions for font embedding in documents, crucial for copyright and licensing. - **File Structure**: Organized into tables with font data like header, metrics, character maps, and glyphs. - **Compatibility**: Widely supported across operating systems such as Windows, macOS, and Unix-based systems. - **File Size**: Varies depending on font complexity and glyph count. - **Font Editing/Creation**: Can be edited and created using various software tools. - **Font Rendering**: Rendered by the operating system's font engine. - **Advanced Typographic Features**: Basic format does not support features like ligatures; extended formats such as TTC and OpenType can. TrueType fonts are essential in digital typography for their quality, scalability, and print media. |
