EZHFTN – draws a half-tone picture from data stored in a rectangular array with the intensity in the picture proportional to the data value. Utility This routine is part of the Halftone utility in NCAR Graphics. To see the overview man page for this utility, type "man halftone". Status EZHFTN is obsolete. It has been…
EZCNTR – draws a two dimensional contour map from data stored in a rectangular array. A number of contouring defaults are used. Status EZCNTR is obsolete. It has been superseded by the contouring package, Conpack.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…
Error_handling – A set of routines for error handling in NCAR Graphics. Synopsis ENTSR – 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…
ERROF – Turns off the internal error flag of SETER. Synopsis CALL ERROF C-Binding Synopsis #include <ncarg/ncargC.h> void c_errof() Description The FORTRAN statement "CALL ERROF" turns off (zeroes) SETER’s internal error flag. ERROF has no arguments. C-Binding Description The C-binding argument descriptions are the same as the FORTRAN argument descriptions. Examples Use the ncargex command…
EPRIN – Prints the current error message. Synopsis CALL EPRIN C-Binding Synopsis #include <ncarg/ncargC.h> void c_eprin() Description If 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 Description The C-binding argument descriptions are the…
ENTSR – Called by a user to set recovery mode in NCAR Graphics. Synopsis CALL ENTSR(IROLD,IRNEW) C-Binding Synopsis #include <ncarg/ncargC.h> void c_entsr(int *irold, int irnew) Description The 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…
