NAME¶
AREDAM - Adds edge segments to an area map.
SYNOPSIS¶
CALL AREDAM (MAP,XCA,YCA,LCA,IGI,IDL,IDR)
C-BINDING SYNOPSIS¶
#include <ncarg/ncargC.h>
void c_aredam (int *map, float *xca, float *yca, int lca, int igi, int idl, int
idr)
DESCRIPTION¶
- MAP
- (an input/output array of type INTEGER) - An array containing an area map
that has been initialized by a call to ARINAM.
Note: As part of initializing the area map, ARINAM stores the dimension of
MAP in MAP(1); therefore, the dimension does not have to be given as an
argument in calls to AREDAM.)
- XCA
- (an input array, dimensioned LCA, of type REAL) - The X coordinates, in
the user coordinate system, of the points defining an edge.
- YCA
- (an input array, dimensioned LCA, of type REAL) - The Y coordinates, in
the user coordinate system, of the points defining an edge.
- LCA
- (an input expression of type INTEGER) - The number of coordinates in XCA
and YCA.
- IGI
- (an input expression of type INTEGER) - Identifier of the group to which
the edge belongs.
- IDL
- (an input expression of type INTEGER) - Identifier of the area that lies
to the left of the edge.
- IDR
- (an input expression of type INTEGER) - Identifier of the area that lies
to the right of the edge.
C-BINDING DESCRIPTION¶
The C-binding argument descriptions are the same as the FORTRAN argument
descriptions.
USAGE¶
The area-map array MAP must have been initialized by a call to ARINAM. Each
subsequent call to AREDAM adds to the area map the LCA-1 edge segments defined
by the points whose user coordinates are in the arrays XCA and YCA. (Points 1
and 2 define the first edge segment, points 2 and 3 define the next edge
segment, points 3 and 4 the next one, and so on.)
EXAMPLES¶
Use the ncargex command to see the following relevant examples: cardb1, cardb2,
carfill, carline, carmap, arex01, cbex01, tareas, fsppoint.
ACCESS¶
To use AREDAM or c_aredam, load the NCAR Graphics libraries ncarg, ncarg_gks,
and ncarg_c, preferably in that order.
