plmtex
(side, disp, pos, just, text); |
Writes text at a specified position relative to the viewport
boundaries. Text may be written inside or outside the viewport, but
is clipped at the subpage 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
just, and the position of
the reference point relative to the viewport is set by
disp and
pos.
side
(const char *, input)
Specifies the side of the viewport along which the text is to
be written. The string must be one of:
b: Bottom of viewport, text written
parallel to edge.
bv: Bottom of viewport, text written at
right angles to edge.
l: Left of viewport, text written
parallel to edge.
lv: Left of viewport, text written at
right angles to edge.
r: Right of viewport, text written
parallel to edge.
rv: Right of viewport, text written at
right angles to edge.
t: Top of viewport, text written
parallel to edge.
tv: Top of viewport, text written at
right angles to edge.
disp
(PLFLT, input)
Position of the reference point of string, measured outwards
from the specified viewport edge in units of the current
character height. Use negative
disp to write within
the viewport.
pos
(PLFLT, input)
Position of the reference point of string along the specified
edge, expressed as a fraction of the length of the edge.
just
(PLFLT, input)
Specifies the position of the string relative to its reference
point. If just=0.,
the reference point is at the left and if
just=1., it is at the
right of the string. Other values of
just give
intermediate justifications.
text
(const char *, input)
The string to be written out.
