The icb file extension is also used for a special version of Truevision Targa format.
This is a format for storing bitmaps that was developed in conjunction with a number of video capture and graphics adapter boards for the PC and Macintosh. The format has thus become popular in the world of still-video editing.
The format was revised in 1989 to add support for new capabilities (thus there are "original" and "new" TGA formats). Fortunately, the "new" format is a superset of the "original", and many applications, even those designed around the "original" format, can read both types of files.
TGA files can contain monochrome images, color images with a palette, and 16-bit, 24-bit and 32-bit TrueColor images. 16-bit images, are usually the most commonly encountered.
TGA files can be uncompressed, or compressed using a Run-length compression scheme.
The "new" TARGA format also can store additional information, including information about when/how the file was created, application specific data, and a thumbnail version of the main image known as a "Postage-stamp image".
Same extension was also used for another bitmap format called Image Capture Board format.
Use any common graphic viewer with Targa support.
Possibly can be converted like any other picture image formats.
