Ezmap_params – This document briefly describes all internal parameters of EZMAP. DescriptionEZMAP has a large group of internal parameters, each of which affects the behavior of one or more of the EZMAP routines. The current values of the internal parameters may be retrieved using the routines MAPGTC, MAPGTI, MAPGTL, and MAPGTR. The values of most…
EZMAP – Allows one to plot maps of the earth according to any of ten different projections, with parallels, meridians, and continental, international, and/or U.S. state outlines. EZMAPA is the name of a supplement to the EZMAP utility that allows users to produce solid-filled maps of the earth. The EZMAPA routines are discussed as part…
EZISOS – Draws an isosurface. SynopsisCALL EZISOS (F,MU,MV,MW,EYE,SLAB,FISO) C-Binding Synopsis#include <ncarg/ncargC.h> void c_ezisos (float *f, int mu, int mv, int mw, float eye[3], float *slab, float fiso) DescriptionF (an input array of type REAL, dimensioned MU x MV x MW) is a three-dimensional array of data defining the function f(u,v,w). The entire array (elements F(IU,IV,IW),…
EZHFTN – draws a half-tone picture from data stored in a rectangular array with the intensity in the picture proportional to the data value. UtilityThis routine is part of the Halftone utility in NCAR Graphics. To see the overview man page for this utility, type "man halftone". StatusEZHFTN is obsolete. It has been replaced by…
EZCNTR – draws a two dimensional contour map from data stored in a rectangular array. A number of contouring defaults are used. StatusEZCNTR is obsolete. It has been superseded by the contouring package, Conpack. See the Conpack entry CPCNRC for a simple EZCNTR replacement. For more complex examples refer to the conpack and conpack_params man…
Error_handling – A set of routines for error handling in NCAR Graphics. SynopsisENTSR – Enters recovery mode. EPRIN – Prints the current error message. ERROF – Turns off the internal error flag. FDUM – A dump routine – the default version just RETURNS. ICFELL – Checks for an outstanding error condition. ICLOEM – Computes the…
ERROF – Turns off the internal error flag of SETER. SynopsisCALL ERROF C-Binding Synopsis#include <ncarg/ncargC.h> void c_errof() DescriptionThe FORTRAN statement "CALL ERROF" turns off (zeroes) SETER’s internal error flag. ERROF has no arguments. C-Binding DescriptionThe C-binding argument descriptions are the same as the FORTRAN argument descriptions. ExamplesUse the ncargex command to see the following relevant…
EPRIN – Prints the current error message. SynopsisCALL EPRIN C-Binding Synopsis#include <ncarg/ncargC.h> void c_eprin() DescriptionIf SETER’s internal error flag is non-zero, the FORTRAN statement "CALL EPRIN" prints the remembered error message associated with the non-zero value. Otherwise, EPRIN does nothing. EPRIN has no arguments. C-Binding DescriptionThe C-binding argument descriptions are the same as the FORTRAN…
ENTSR – Called by a user to set recovery mode in NCAR Graphics. SynopsisCALL ENTSR(IROLD,IRNEW) C-Binding Synopsis#include <ncarg/ncargC.h> void c_entsr(int *irold, int irnew) DescriptionThe FORTRAN statement "CALL ENTSR(IROLD,IRNEW)" is normally used to enter recovery mode and save the previous value of the internal error-recovery flag, but it can also be used to exit from recovery…
