NAME

       PWRITX - 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

       PWRITX is obsolete.  It has been replaced by the PLCHHQ, PLCHMQ, and PLCHLQ entries of the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

       PWRITX 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 PWRITX (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.
                   There may also be embedded function codes describing how certain characters
                   are to be drawn.

       NCHAR       (an input parameter of type INTEGER) giving the number of characters in the
                   IDPC string.  NCHAR includes a count of all characters in the string including
                   the function codes.

       JSIZE       (an input parameter of type INTEGER) giving the width of the characters to be
                   drawn.

                           0  -  1.0 * the size of the digitized
                                       characters in the database
                           1  -  1.5 * digitized size
                           2  -  2.0 * digitized size
                           3  -  3.0 * digitized size

                           If greater than 3:

                           Principal characters =          JSIZE
                           Indexical characters =  (13/21)*JSIZE
                        Cartographic characters =  ( 9/21)*JSIZE

                   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 PWRITX.  In GKS, text size is given in terms of character heights.
                   In PWRITX, 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 PWRITX, load the NCAR Graphics libraries ncarg, ncarg_gks, ncarg_c, and ncarg_c,
       preferably in that order.
