This is the user's and reference manual for `Picture's, a simple structured graphics model expressed in the functional language Haskell. It provides a simple model of graphics that can be used in functional programs to create simple 2D graphical output. The principles and basic constructs to describe a two dimensional picture are explained by working through a number of examples. The manual also contains a reference of the large number of useful combinators that have been derived from the core constructs offered by Pictures.
