ncl_pwrity man page

PWRITY — draws text and other characters using polylines.

Utility

This routine is part of the Pwrite_family utility in NCAR Graphics. To see the overview man page for this utility, type "man pwrite_family".

Status

PWRITY is obsolete. It has been replaced by the PLCHHQ, PLCHMQ, and PLCHLQ entries of the Plotchar utility.

PWRITY continues to be provided for compatibility of early NCAR Graphics codes. If you are writing new code, we suggest that you use Plotchar.

Synopsis

CALL PWRITY (X,Y,IDPC,NCHAR,JSIZE,JOR,JCTR)

Description

X
(an input parameter of type REAL) defining the X world coordinate of the text string to be drawn using polylines.
Y
(an input parameter of type REAL) defining the Y world coordinate of the text string to be drawn using polylines.
IDPC
(an input string of type CHARACTER) which are the characters to be drawn.
NCHAR
(an input parameter of type INTEGER) giving the number of characters in the IDPC string.
JSIZE
(an input parameter of type INTEGER) giving the width of the characters to be drawn.

0 - 8./1023. NDCs
1 - 12./1023. NDCs
2 - 16./1023. NDCs
3 - 24./1023. NDCs

If greater than 3:

FLOAT(JSIZE)/1023. NDCs

One can relate these sizes to a viewport in normalized device coordinates (each axis runs 0. to 1.) by dividing by 1023. That is a character of width .05 would take up 5% of the possible picture width meaning that less than 20 characters could fit on a line.

Note that there is an important difference in how text sizes are handled in GKS versus PWRITY. In GKS, text size is given in terms of character heights. In PWRITY, text size (JSIZE) is given in character width.
JOR
(an input parameter of type INTEGER) giving the orientation at which the IDPC string is to be drawn. JOR is measured counter-clockwise from the positive X axis.
JCTR

(an input parameter of type INTEGER) giving the centering option for the IDPC character string.

 0, (X,Y) is the center of the entire IDPC string.
-1, (X,Y) is the center of the left edge of the
          first character.
 1  (X,Y) is the center of the right edge of the
          last character.

Access

To use PWRITY, load the NCAR Graphics libraries ncarg, ncarg_gks, ncarg_c, and ncarg_c, preferably in that order.
