Plotchar_params – This document briefly describes all the internal parameters of Plotchar. Description The following shows all of the internal parameters that affect the behavior of PCHIQU. Each entry includes the name of a parameter, its FORTRAN type, its default value, and a short description of the parameter. Internal Parameters of PCHIQU ‘AS’ – Real…
Plotchar – Allows a user to draw characters of high, medium, or low quality. Synopsis PCHIQU (or PLCHHQ) – Draws high quality characters. By default, it uses the same database as the old NCAR Graphics routine PWRITX, but it can also use characters from any of the fontcap-defined databases, it has an improved interface, and…
PCMEQU – Draws characters of "medium quality". It does this by drawing lines, just as PCHIQU does, but it does not produce quite such fancy characters. No function codes may be used. Using PCMEQU to draw a given string of characters will create a larger metafile than if PCLOQU were used, which may be a…
PCLOQU – Draws characters of "low quality" by calling the GKS character-drawing routines. No function codes may be used. Using PCLOQU to draw a given string of characters will create a smaller metafile than if PCHIQU or PCMEQU were used; the results will depend on capabilities of the translator. PLCHLQ is an alternate name for…
PCHIQU – Draws high quality characters. By default, it uses the same database as the old NCAR Graphics routine PWRITX, but it can also use characters from any of the fontcap-defined databases, it has an improved interface, and it has many more capabilities than PWRITX. PLCHHQ is an alternate name for the routine PCHIQU. Synopsis…
PERIML – Draws a labeled perimeter with inward-pointing tick marks. The directions and lengths of tick marks may be changed by calling TICKS and/or TICK4. Synopsis CALL PERIML (MJRX,MNRX,MJRY,MNRY) C-Binding Synopsis #include <ncarg/ncargC.h> void c_periml (int mjrx, int mnrx, int mjry, int mnry) Description MJRX, MNRX, MJRY, and MNRY (input expressions of type INTEGER) specify…
PERIM3 – Draws the projection of a rectangular perimeter in a plane parallel to one of the three coordinate planes, with inward-pointing tick marks at specified intervals. Synopsis CALL PERIM3 (MAJOR1,MINOR1,MAJOR2,MINOR2,IAXIS,VALUE) C-Binding Synopsis #include <ncarg/ncargC.h> void c_perim3 (int major1, int minor1, int major2, int minor2, int iaxis, float value) Description MAJOR1 (an input expression of…
PERIM – Draws an unlabeled perimeter with inward-pointing tick marks. The directions and lengths of tick marks may be changed by calling TICKS and/or TICK4. Synopsis CALL PERIM (MJRX, MNRX, MJRY, MNRY) C-Binding Synopsis #include <ncarg/ncargC.h> void c_perim (int mjrx, int mnrx, int mjry, int mnry) Description MJRX, MNRX, MJRY, and MNRY (input expressions of…
PCSETR – Sets the value of an internal parameter of type REAL or INTEGER. Synopsis CALL PCSETR (PNAM,RVAL) C-Binding Synopsis #include <ncarg/ncargC.h> void c_pcsetr (char *pnam, float rval) Description PNAM (an input constant or variable of type CHARACTER) specifies the name of the parameter to be set. The name must appear as the first two…
PCSETI – Sets the value of an internal parameter of type INTEGER or REAL. Synopsis CALL PCSETI (PNAM,IVAL) C-Binding Synopsis #include <ncarg/ncargC.h> void c_pcseti (char *pnam, int ival) Description PNAM (an input constant or variable of type CHARACTER) specifies the name of the parameter to be set. The name must appear as the first two…
PCSETC – Gives a new character value to a specified internal parameter. Synopsis CALL PCSETC (PNAM,CVAL) C-Binding Synopsis #include <ncarg/ncargC.h> void c_pcsetc (char *pnam, char *cval) Description PNAM (an input constant or variable of type CHARACTER) specifies the name of the parameter to be set. The name must appear as the first two characters of…
PCRSET – Resets all parameters to their initial default values. Synopsis CALL PCRSET C-Binding Synopsis #include <ncarg/ncargC.h> void c_pcrset() Description PCRSET has no arguments. Usage Calling this routine restores all Plotchar parameters to their initial default values. For a complete list of parameters available in this utility, see the plotchar_params man page. Examples Currently, there…
PCPNWI – A function of type CHARACTER*16. Synopsis CHARACTER*16 PCPNWI,ENAM ENAM = PCPNWI (PNAM,IPAI) C-Binding Synopsis #include <ncarg/ncargC.h> void c_pcpnwi (char *pnam, int *ipai) Description PNAM (an input constant or variable of type CHARACTER) is a character string, the first two characters of which are the name of an internal parameter array of Plotchar (currently,…
PCMPXY – This routine is normally not called directly by the user (though it can be). It is called by each of the routines PCHIQU, PCMEQU, and PCLOQU when the user has set the mapping flag ‘MA’ nonzero to request mapping of characters from one X/Y coordinate system to another. Synopsis CALL PCMPXY (IMAP,XINP,YINP,XOTP,YOTP) C-Binding…
PCMEQU – Draws characters of "medium quality". It does this by drawing lines, just as PCHIQU does, but it does not produce quite such fancy characters. No function codes may be used. Using PCMEQU to draw a given string of characters will create a larger metafile than if PCLOQU were used, which may be a…
