Notes on a general 2D API

Introduction and Motivation

There is a need for a high-level Go API for developers and designers to think in terms of high level objects that make up a visual display. The objects will be familiar to anyone using a modern illustration program (text, images, lines, arcs, circles, curves, etc). The API should facilitate the artful arrangement of these elements on a scalable 2D canvas.

The principle is to keep the number of methods small and consistent, using a common set of arguments for location (x, y), and dimentions (w, h).
