NIH Image is a public domain program for the Macintosh for doing digital image processing and analysis. It can acquire, display, edit, enhance, analyze, print, and animate grayscale and color images. It features multiple windows, MacPaint-like editing and 8 levels of magnification. It supports Data Translation and Scion frame grabber cards. Image requires at least 4MB of RAM and 8-bit video.
Files are in one of three formats.
They permit storage of a complete Mac file on a non-Mac system, such as this server. Most files were compressed using the Mac utility Stuffit 1.5.1 and uploaded using Fetch, which does the BinHex or MacBinary encoding. Both utilities can be found in the util directory. Unfortunately, Fetch requires a Mac directly connected to the Internet. There is an NIH Image mailing list.
