The user is asked to select an imagery group. Band files in the group that are currently assigned to the red, green, and blue color bands are displayed along the left edge of the user's graphics display frame, and a composite image of these bands is displayed in the right portion of the display frame. A small matrix appears in the lower left portion of the display frame, and reflects current red, green, and blue band file color assignments. Red, green, and blue color boxes appear next to the names of the image band files to which they are currently assigned. The user can change current color assignments by clicking the mouse cursor beside desired color assignments.
A menu along the bottom of the graphics display frame indicates that the user can also replot and enlarge the composite image on display, or quit the program, by clicking the mouse cursor on the desired option.
The GRASS program i.group can also be used to assign red, green, and blue colors to imagery group band files.
This program is interactive and requires no command line arguments. The user must be running a graphics monitor to use this program.
To store color composite output into a map, the user will utilize i.composite.
