Returns a new font object representing this variation, from which you can get glyphs and perform layout as normal. Keys are variation names, and values are objects with axis settings. Instances that the designer has specified. This property returns an object describing these named variation The font designer may have picked out some variations that they think look particularly good, for example a light, regular,Īnd bold weight which would traditionally be separate fonts. Min, default, and max properties for the axis. Keys are 4 letter axis tags, and values include name, Returns an object describing the available variation axes. Font designers specify the minimum, default, and maximum values for eachĪxis they support, and allow the user fine grained control over the rendered text. Various axes including weight, width, and slant. Variation fontsįontkit has support for AAT variation fonts, where glyphs can adjust their shape according to user defined settings along If this is an AAT font, the OpenType feature tags are mapped to AAT features. In addition to the default set, or an object mapping OpenType features to a boolean enabling or disabling each. The features parameter is either an array of OpenType feature tags to be applied GlyphPosition objects include 4 properties: xAdvance, yAdvance, xOffset, This method returns a GlyphRun object, which includes an array of Glyphs and GlyphPositions for the given string. toSVG ( ) // create a font subset var subset = font. layout ( 'hello world!' ) // get an SVG path for a glyph var svg = run. returns a GlyphRun, describing glyphs and positions. openSync ( 'font.ttf' ) // layout a string, using default shaping features. Var fontkit = require ( 'fontkit' ) // open a font synchronously var font = fontkit. Font subsetting support - create a new font including only the specified glyphs.Support for AAT variation glyphs, allowing for nearly infinite design control over weight, width, and other axes.emoji), including Apple’s SBIX table, and Microsoft’s COLR table Supports TrueType (glyf) and PostScript (CFF) outlines.Support for getting glyph vector paths and converting them to SVG paths, or rendering them to a graphics context.Apple Advanced Typography (AAT) glyph substitution features (morx table).Advanced OpenType features including glyph substitution (GSUB) and positioning (GPOS).Supports reading glyph metrics and laying out glyphs, including support for kerning and other advanced layout features (see below).Supports mapping characters to glyphs, including support for ligatures and other advanced substitutions (see below).Supports TrueType (.ttf), OpenType (.otf), WOFF, WOFF2, TrueType Collection (.ttc), and Datafork TrueType (.dfont) font files.It supports many font formats, advanced glyph substitution and layout features, glyph path extraction, color emoji glyphs, font subsetting, and more.
