text); |
Writes text at a specified position and inclination and with a
specified shear within the viewport. Text is clipped at the viewport
boundaries. The reference point of a string lies along a line passing
through the string at half the height of a capital letter. The
position of the reference point along this line is determined by
, and the reference
point is placed at world coordinates
just( within the viewport. The
inclination and shear of the string is specified in terms of
differences of world coordinates making it easy to write text parallel
to a line in a graph.
wx, wy,
wz)
wx
(PLFLT, input)
x world coordinate of reference point of string.
wy
(PLFLT, input)
y world coordinate of reference point of string.
wz
(PLFLT, input)
z world coordinate of reference point of string.
dx
(PLFLT, input)
Together with , this specifies the inclination of
the string. The baseline of the string is parallel to a line
joining dy and
dz( to x, y,
z)
(.
x+dx,
y+dy,
z+dz)
dy
(PLFLT, input)
Together with ,
this specifies the inclination of the string.
dx and
dz
dz
(PLFLT, input)
Together with ,
this specifies the inclination of the string.
dx and
dy
sx
(PLFLT, input)
Together with , this specifies the shear of
the string. The string is sheared so that the characters are
vertically parallel to a line joining sy and
sz
( to x, y,
z)
(.
If x+sx,
y+sy,
z+sz) then the text is not
sheared.
sx = sy
= sz = 0.)
sy
(PLFLT, input)
Together with ,
this specifies shear of the string.
sx and
sz
sz
(PLFLT, input)
Together with ,
this specifies shear of the string.
sx and
sy
just
(PLFLT, input)
Specifies the position of the string relative to its reference
point. If ,
the reference point is at the left and if
just=0., it is at the
right of the string. Other values of
just=1. give
intermediate justifications.
just
text
(const char *, input)
The string to be written out.
