       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 the routine PCLOQU.




       #include <ncarg/ncargC.h>

       void c_pcloqu (float xpos, float ypos, char *chrs,
       float size, float angd, float cntr)


       XPOS,YPOS   (input expressions of type REAL) specify positioning coordinates for the
                   characters to be drawn. If the internal parameter ´MA´ has the value 0, these
                   are given in the current user coordinate system; otherwise, they are given in
                   an arbitrary X/Y coordinate system, as implied by the value of ´MA´ and the
                   nature of the routine CPMPXY. (For example, if ´MA´ has the value 1 and the
                   default version of CPMPXY is being used, then XPOS is a longitude, in degrees,
                   and YPOS is a latitude, in degrees.)  The argument CNTR (described below)
                   specifies how the characters are to be positioned relative to the point

       CHRS        (an input constant or variable of type CHARACTER) contains a character string
                   to be drawn. The number of characters in CHRS is taken to be LEN(CHRS); to use
                   characters "m" through "n" from a character variable CHRS, use the FORTRAN-77
                   substring notation "CHRS(m:n)". The string may include any of the 95
                   characters space, exclamation point, double quote, pound sign, dollar sign,
                   percent sign, ampersand, apostrophe, left parenthesis, right parenthesis,
                   asterisk, plus sign, comma, minus sign, period, slash, 0-9, colon, semi-colon,
                   less than sign, equals sign, greater than sign, question mark, at sign, A-Z,
                   left square bracket, backslash, right square bracket, hat, underscore,
                   backwards quote, a-z, left curly bracket, vertical bar, right curly bracket,
                   and tilde. Function codes, like those in calls to PCHIQU, may not be used.

       SIZE        (an input expression of type REAL) specifies the desired character size. If
                   the internal parameter ´MA´ is zero, then the following comments apply:

                   ·      If SIZE is less than or equal to zero, its absolute value specifies the
                          size as a multiple of a default digitized size on a 1024x1024 grid, on
                          which blanks are 16 units wide.

                   ·      If SIZE is greater than zero, but less than one, it specifies the
                          desired width of a blank as a fraction of the distance across the
                          plotter frame. This is the recommended scheme.

                   ·      If SIZE is greater than or equal to one, it specifies the desired width
                          of a blank in plotter coordinates, as defined by default or by a user´s
                          call to the SPPS routine SETI.  Note that use of the routine SETI is
                          now discouraged.

                   If ´MA´ is nonzero, then SIZE is the desired width of a blank as a value in
                   the X/Y coordinate system in which XPOS and YPOS are given.

                   Note that SIZE is defined in such a way as to be consistent with PCHIQU.

       ANGD        (an input expression of type REAL) is the angle, in degrees counterclockwise
                   from the positive X axis, at which the character string is to be written.

       CNTR        (an input expression of type REAL) is the centering option, as follows:

                   ·      CNTR < 0. means that (XPOS,YPOS) is the center of the left edge of the
                          first character.

                   ·      CNTR > 0. means that (XPOS,YPOS) is the center of the right edge of the
                          last character.

                   ·      CNTR = 0. means that (XPOS,YPOS) is the midpoint of the string.

                   Note that this argument is not quite the same as that for PCHIQU (though it
                   does include the three most useful cases).

                   Upon return from PCLOQU, all arguments are unchanged.


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

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