The first prompt asks the user for the imagery group whose files are to be used.
The following menu is then displayed:
Please indicate which files to use for red, green, and blue colors. You may leave any color out. You may specify more than one color per file. However, each color may only be specified once. For example, to get a full color image, specify r,g,b for 3 different files. To get a grey scale image, specify rgb for a single file. b__ spot.1 g__ spot.2 r__ spot.3 ___ spotclass ___ spotreject AFTER COMPLETING ALL ANSWERS, HIT <ESC> TO CONTINUE (OR <Ctrl-C> TO CANCEL)The user is then allowed to check the choice of bands:
Colors assigned as follows: RED: spot.3@mapsetname GREEN: spot.2@mapsetname BLUE: spot.1@mapsetname Look ok? (y/n) [y]The color table that is created has 1000 colors (10 saturation levels (or shades) per primary color (blue, green, red)). The number of colors that can be displayed at one time on a color graphics monitor will depend on the graphics monitor being used. For example, if the graphics monitor can only display 512 colors at one time, then the user must run the GRASS command d.colormode mode=fixed before displaying the raster map layer. The colors that cannot be displayed will be assigned to the nearest displayable color, and the raster map layer will retain its relative color accuracy. If the user is in float colormode, however, the raster map layer displayed on the graphics monitor will not accurately reflect the map's real color assignments.
The user is then asked to name the composite image raster map layer. The percentage completed is echoed to the screen and r.support files are created automatically.
