Abstract: Methods and devices for animating variable fonts may include receiving a request to animate one or more glyphs of a variable font in a design space based on one or more animation parameters. The methods and devices may also include determining an animation path in the design space for the one or more glyphs based on the animation parameters and calculating a set of keyframes having respective keyframe positions along the animation path. The methods and devices may include constructing glyph outline data of the one or more glyphs for each keyframe in the set of keyframes. The methods and devices may include generating intermediate glyph outline data at one or more intermediate positions between the keyframe positions and transmitting the glyph outline data and the intermediate glyph outline data.

Abstract: Conditional determination of glyph substitution (GSUB) lookups or glyph positioning (GPOS) lookups in the process of rendering a string of text as a sequence of glyphs is described. A process can include receiving a string of text comprising a sequence of characters, obtaining a sequence of glyph identifiers (IDs) corresponding to the sequence of characters, and determining that a context of the string of text satisfies a condition. Based at least in part on the context satisfying the condition, an alternate lookup can be determined and executed in lieu of a default lookup. Execution of the alternate lookup causes a GSUB operation or a GPOS operation to be performed on the sequence of glyph IDs to ultimately cause the string of text to be rendered on a display as a sequence of glyphs with a typographical feature applied thereto.
