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.
