Release 3 of the Image Addon: Help Front Page
by Zachary X. Reiter and Clifford A. Reiter (reiterc@lafayette.edu)
June 2003

Like the other releases of the image addon for J, this addon gives utilities for reading and writing images in a variety of formats from J. While the emphasis is on 24 bit images, there is some support for movies and 8-bit images. We have found the addon very useful and use it regularly. However, some variants of the image and movie types may not be successfully read. Moreover, the software is powerful, so users should be prudent and work on files that have been backed up.

The Main Scripts

The main utilities are organized into 4 scripts (each requiring those above it): The addon utilities are implemented with a combination of J defined functions and *.dll or *.so library functions created from several open sources. There are also several auxilary scripts used for a variety of tasks: viewing images and data, creating raster images of text, wrapping images onto an annulus for CD labels, and giving samples of possible usage.

Image3 Addon Labs

The help sections (see links below) describe the main addon features. However, three labs are also available to introduce the addon features.
