What is MAP ?

MAP is ImageMagick's colormap format: a palette of colours followed by one index per pixel that says which palette entry to draw. The file has no header, so the image width and height are not stored in it. It is an output format for indexed-colour work such as embedded displays, retro graphics and custom image pipelines.

Why Convert CAL to MAP file?

CAL is the CALS raster format, the black-and-white image format of technical manuals, engineering drawings and defence documentation, usually compressed with the same Group 4 scheme fax machines use. MAP is ImageMagick's colormap format: a palette of colours followed by one index per pixel. Despite the name it has nothing to do with geographic maps; it is meant for indexed-colour work such as embedded displays, firmware graphics and custom image pipelines.

The two fit together unusually well. A CALS image is bilevel — every pixel is black or white — so its palette has just two entries and nothing is lost getting it into MAP form, where photographs would show banding. The one thing to keep track of is size: MAP files carry no header, so the image width and height are not stored. Note them before converting, because whatever reads the MAP back has to be told them.
