The Iconography Encyclopedia

Published by The Iconography Company, the encyclopedia is a reference vocabulary for people who draw, commission and review icon sets. Entries cover construction anatomy such as base, modifier, stroke and end cap, vector concepts like anchor points, Bézier curves and boolean operations, and typographic, colour and accessibility terms.

Definitions are written for practice, not just glossaries: readability is separated from legibility, visual weight accounts for naturally lighter glyphs such as chevrons, and stroke weight lists the 1, 1.25, 1.5 and 2 px values common in product iconography. A directory view lists every term for browsing.
