Abstract

The Image Display Interface (IDI) is an international standard for displaying astronomical data on an image display. The specification of the interface is given in Terrett et al (1988). This guide is an introduction to programming with IDI, and describes the details of the current implementation. The user should refer to the specification document, for details of the subroutine calls.
