NAME

       PWRZS - A character-plotting routine for plotting characters in three-space when using
       SRFACE.

SYNOPSIS

       CALL PWRZS (X,Y,Z,ID,N,ISIZE,LINE,ITOP,ICNT)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_pwrzs (float x, float y, float z, char *id,
       int n, int isize, int line, int itop, int icnt)

DESCRIPTION

       X,Y,Z       Positioning coordinates for the characters to be drawn.  These are floating
                   point numbers in the same three-space as used in SRFACE.

       ID          Character string to be drawn. ID is of type CHARACTER.

       N           The number of characters in ID.

       ISIZE       Size of the character:

                   • If between 0 and 3, ISIZE is 1., 1.5, 2., or 3. times a standard width equal
                     to 1/128th of the screen width.

                   • If greater than 3, ISIZE is the character width in plotter address units.

       LINE        The direction in which the characters are to be written.

                        1 = +X -1 = -X
                        2 = +Y -2 = -Y
                        3 = +Z -3 = -Z

       ITOP        The direction from the center of the first character to the top of the first
                   character (the potential values for ITOP are the same as those for LINE as
                   given above). Note that LINE cannot equal ITOP even in absolute value.

       ICNT        Centering option.

                   -1 (X,Y,Z)  is the center of the left edge of the first character.

                   0 (X,Y,Z)   is the center of the entire string.

                   1 (X,Y,Z)   is the center of the right edge of the last character.

                   Note that the hidden character problem is solved correctly for characters
                   near, but not inside, the three-space object.

C-BINDING DESCRIPTION

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

USAGE

       Call PWRZS after calling SRFACE and before calling FRAME.

EXAMPLES

       Use the ncargex command to see the following relevant examples: fsrpwrzs, tpwrzs.

ACCESS

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