SYNOPSIS

ICIR=MAPACI(IAID)

C-BINDING SYNOPSIS

#include <ncarg/ncargC.h>

int c_mapaci (int iaid)

DESCRIPTION

IAID

(an input expression of type INTEGER) is an area identifier for one of the areas defined by the set of boundary lines added to an area map by a call to MAPBLA.

C-BINDING DESCRIPTION

The C-binding argument description is the same as the FORTRAN argument description.

USAGE

Executing the statement "ICIR=MAPACI(IAID)" gives ICIR a value between 1 and 7, inclusive, that may be used to select a color index for the area whose area identifier is IAID. It is guaranteed that MAPACI will not return the same value for adjacent areas; this fact can be used to ensure that adjacent areas will have different colors.

Note that it is the responsibility of the user to define the colors associated with color indices used; this is done by calling the GKS routine GSCR.

EXAMPLES

Use the ncargex command to see the following relevant example: eezmpa.

ACCESS

To use MAPACI or c_mapaci, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
