HT LetterSpacer: Everything You Always Wanted to Know About Automatic Spacing But Were Afraid to Ask

HT LetterSpacer is a method for spacing glyphs on finished fonts as well as during the design and production process. It proposes a way to measure the white space on the glyphs sides and equalize it according to glyphs groups to define sidebearings and advanced width. This approach can be understood graphically and it can be applied by the type designer in several ways to different types of scripts. Actually it works as Macro script for Glyphs App. As a Libre software, it can be ported to different editors and programming languages. In this talk I will graphically explain the basic ideas behind the method, its origins, its advantages and examples of use.
