mapiqm(3NCARG)
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 EXAMPLES Use the ncargex command to see the following relevant example: cmpitm,
ACCESS
To use MAPIQM or c_mapiqm, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
