Abstract
In this paper, we describe a software package, LEDA, for editing two-dimensional images and films. It is written in Turbo-C and was first conceived to work with a high-resolution graphics card (Adage PG90/10, 2,048 × 1,023 × 8 bits) on an IBM PC/AT or compatible computer. The program is intended for managing images and films used in the fields of visual psychophysics, electrophysiology, and so forth.
