Abstract
Embodiments presented in this disclosure provide for dynamic application of user selected visual accessibility transforms onto glyphs of standard fonts so that, for instance, a user device can present textual content to a user in a form personalized by the user to be more readable. In accordance with some aspects, a user selection of a font transformation is received. A set of initial control points of an initial glyph is transposed based on the font transformation to generate a set of modified control points. A modified glyph is constructed using differential evolution based at least on the set of initial control points and the set of modified control points.
