A Font Engine is a software component that manages the rendering of text in digital applications. It interprets font files, which contain the visual representations of characters, and converts them into a format that can be displayed on screens. This process involves handling various font formats, such as TrueType and OpenType, ensuring that text appears correctly in different sizes and styles. In addition to rendering, a Font Engine also supports features like kerning, which adjusts the spacing between characters, and ligatures, which combine certain character pairs for a more visually appealing appearance. Popular examples of Font Engines include FreeType and the font rendering systems used in Adobe products.
