NAME¶

Areas - A set of routines allowing you to create an area map from a set of edges and then to use the area map for various purposes.

SYNOPSIS¶

ARINAM - Initializes an area map. AREDAM - Adds edges to an area map. ARMVAM - Moves an area map from one integer array to another. ARPRAM - Preprocesses an area map. ARSCAM - Obtains definitions of areas created by edges in an area map. ARDRLN - Draws a polyline masked by a given area map. ARGTAI - Gets area identifiers associated with a given point. ARGETI - Retrieves the integer value of an Areas parameter. ARGETR - Retrieves the real value of an Areas parameter. ARSETI - Provides a new integer value for an Areas parameter. ARSETR - Provides a new real value for an Areas parameter. ARDBPA - Produces a picture of a specified portion of the area map.

C-BINDING SYNOPSIS¶

#include <ncarg/ncargC.h> c_arinam c_aredam c_arpram c_arscam c_ardrln c_argtai c_argeti c_arseti c_ardbpa

ACCESS¶

To use the Areas Fortran or C routines, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.

MESSAGES¶

When error conditions are detected, the support routine SETER is called. By default, SETER writes a message to the standard error file (as defined by I1MACH(4)) and then terminates execution. It is possible to put SETER into recovery mode and regain control after a recoverable error (which includes all of the possible errors). The possible error messages are listed below. All errors are recoverable in the sense that a user program which has called ENTSR to set recovery mode will get control back after one of these errors occurs.
