NAME¶
MAPIQM - Terminates a string of calls to the routine MAPITM.
SYNOPSIS¶
CALL MAPIQM (IAMA,XCRA,YCRA,MCRA,IAAI,IAGI,NOGI,ULPR)
C-BINDING SYNOPSIS¶
#include <ncarg/ncargC.h>
void c_mapiqm (int *iama, float *xcra, float *ycra,
int mcra, int *iaai, int *iagi, int nogi,
int (*ulpr)(float *xcra, float *ycra, int *mcra,
int *iaai, int *iagi, int *nogi))
DESCRIPTION¶
- IAMA
- (an input/output array of type INTEGER, dimensioned as specified in a call
to the AREAS initialization routine ARINAM) is the array containing the
area map against which lines drawn by MAPIQM will be masked.
- XCRA and YCRA
- (scratch arrays of type REAL, each dimensioned MCRA) are to be passed by
MAPIQM to the AREAS routine ARDRLN, which uses them in calls to the user
line-processing routine ULPR. They will hold the X and Y coordinates of
points in the fractional coordinate system defining some portion of the
projection of a user-defined polyline on the globe.
- MCRA
- (an input expression of type INTEGER) is the size of each of the arrays
XCRA and YCRA. The value of MCRA must be at least two. For most
applications, the value 100 works nicely.
- IAAI and IAGI
- (scratch arrays of type INTEGER, each dimensioned NOGI) are to be passed
by MAPIQM to the AREAS routine ARDRLN, which uses them in calls to the
user line-processing routine ULPR. They will hold area identifier/group
identifier pairs for the area containing the polyline fragment defined by
XCRA and YCRA.
- NOGI
- (an input expression of type INTEGER) is the size of each of the arrays
IAAI and IAGI. The value of NOGI must be greater than or equal to the
number of groups of edges placed in the area map in IAMA.
- ULPR
- is the name of a user-provided line-processing routine. This name must
appear in an EXTERNAL statement in the routine that calls MAPITM, so that
the compiler and loader will know that it is the name of a routine to be
called, rather than the name of a variable.
C-BINDING DESCRIPTION¶
The C-binding argument descriptions are the same as the FORTRAN argument
descriptions.
USAGE¶
You must call MAPITM once for each point along the line. After the last call to
MAPITM for a given line, you must call MAPIQM to signal the end of the line.
For more information, see the man pages for the routines MAPIT and MAPITM. SH

ACCESS¶
To use MAPIQM or c_mapiqm, load the NCAR Graphics libraries ncarg, ncarg_gks,
and ncarg_c, preferably in that order.
