text); |
Writes text at a specified position and inclination 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
, the reference point
is placed at world coordinates just( within the viewport. The
inclination 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.
x,
y)
x
(PLFLT, input)
x coordinate of reference point of string.
y
(PLFLT, input)
y 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( to
x,
y)(.
x+dx,
y+dy)
dy
(PLFLT, input)
Together with ,
this specifies the inclination of the string.
dx
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.
Redacted form: plptex(x, y, dx, dy, just, text)
This function is used in example 2-4,10,12-14,20,23,24,26.
