OpenType variable fonts: How to use fewer fonts and get a lot more typographic richness

The OpenType font format has been extended with an exciting new technology, OpenType Font Variations. An OpenType variable font is a single font that can behave like many separate fonts by supporting continuous variation between different designs defined in the font. This is the biggest development in OpenType since the introduction of OpenType itself! In this video, we give an overview of OpenType variable fonts, show how some of the capabilities of variable fonts may already be accessible in your existing apps, and describe new DirectWrite APIs that will enable you to take advantage of the full capabilities of this new OpenType format.
