PICO — A picture editor

Abstract

PICO is an interactive editor for digitized graphic images. Editing operations are defined in a simple expression language based on the C language. The editor treats images as an ordered set of pixel structures stored in two-dimensional arrays. PICO checks editing commands for syntax, translates them into programs, optimizes and then executes them, all within a few seconds of run time. The command structure is similar to that of conventional multifile text editors with options for reading, writing, and transforming digitized images.
