NAME
    lsytle - Select font, size, direction, color of text string to draw,
              and background color to paint
    ptext  - Draw text string
              The string can be aligned left, right or center, with/without
              background color painting.
    pcstr  - Draw Courier font string in black

SYNOPSIS

      call lstyle(font, high, angle, itcol, ibcol)
  font    [char]  Character string defining literal font style
                   (3 chars or less.  4th char and the behind are neglected.)
        1st char: 'T'|'H'|'C'|'S'|'K'|'M'|'G' (may be a small letter), which
                   stands for Times | Helvetica | Courier | Symbol | Kanji |
                   Mincho | Gothic , where Mincho and Gothic are equivalent to
                   {Kanji & Fine} and {Kanji & Bold}, respectively.
        2nd/3rd char: modifiers (may be a small letter)
                    'B' (Bold) / 'F' (Fine: disable bold)
                    'O','I' (Oblique,Italic) / 'N','R' (Normal,Roman)
                    Others have no effect.
                  If conflicting each other, the latter is effective.
        (e.g.) 'Mincho' : 'cho' is neglected, 'i' is overridden by 'n', then
                           as a result {Kanji & Fine & Normal}.
               'Courier': 'rier' is neglected, 'u' has no effect, then
                           as a result {Courier & Fine & Oblique}.
  high    [float] Height (in cm) describing the font size
                  Actual character size is dependent on the font, the ratio of
                   actual size to the specified height is about 85% for Kanji
                   fonts, about 70% for Times and Helvetica, and about 60% for
                   Courier.
                  The range of background color painting is 125% of the height
                   specified, 100% above baseline and 25% below baseline.
  angle   [float] Direction angle to draw text (in degrees from +X axis)
  itcol   [int]   Color of text
  ibcol   [int]   Color of background
        Color values for itcol, and ibcol :
            0 thru 16777215 : 24bit color code, 8 bit each for R,G,B
            0 thru -255 : monochromatic gray level from black to white
             [ 0 : black ; -255,16777215 : white]
            If itcol is out-of-range, black color is assigned for text color.
            If ibcol is out-of-range (for example ibcol=-999), the background
             is ragarded as colorless transparent, i.e., rectanglar background
             painting is not performed.

      call ptext(text, ltxt, xp, yp, kp)
  text    [char]  Text string to be drawn with pre-selected font
  ltxt    [int]   Length (number of bytes) of text string
  xp, yp  [float] Coordinates (in cm) of base point to draw string
  kp      [int]   If kp=0, string (lower left) is started at the base point.
                  If kp=1, string (lower right) is ended at the base point.
                  If kp=2, middle center of string is adjusted to the base
                   point (xp,yp).
                  Else (kp>2 or 0>kp), same as kp=0.

      call pcstr(xp, yp, chi, str, angle, ns)
  xp, yp  [float] Coordinates (in cm) of base point to draw string
  chi     [float] Height (in cm) of effective character size
                   [different from 'high' specification in 'lstyle']
  str     [char]  Text string to be drawn with Courier font
  angle   [float] Direction angle to draw text (in degrees from +X axis)
  ns      [int]   Number of bytes of text string
                  If given as positive value, string (lower left) is started
                   from the base point (xp,yp).
                  If given as negated value, end point (lower right) of the
                   string is adjusted to the base point (xp,yp).

NAME
    pmark - Draw a centered symbol mark

SYNOPSIS
      call pmark(mark, xp, yp, size, thick, icol)
  mark    [int]   Mark identifier (0-9)
                  Refer to EXAMPLE for each mark shape.
                  If mark>9 or 0> mark, black solid circle with 'size'
                   dimension (mark=0, thick=0., and icol=0) is assumed.
  xc, yc  [float] Coordinates (in cm) of center of the mark to be drawn
  size    [float] Dimension (in cm) of mark
  thick   [float] Line thickness (in cm) to draw mark
                  If thick=0., it has special meaning 'solid' for mark
                   identifier 0 thru 6, the inside of the mark is painted
                   with the color specified, and further the inside of inner
                   circle in case of mark=1 is painted with white.
  icol    [int]   Color of mark
                   0 thru 16777215 : 24bit color code, 8 bit each for R,G,B
                   0 thru -255 : monochromatic gray level from black to white
                    [ 0 : black ; -255,16777215 : white]
                   If icol is out-of-range (icol>16777215 or -255>icol),
                    black color (icol=0) is assigned.
