Mode 0 starts the polygon mode, in which the following commands can be
used:
-
AA, AR, AT, CI, DF, IN, PA, PD, PE, PMl, PM2, PR, PU, PR.
Reset command <ESC> E can also be given. The polygon stored using these
commands can be edged (using EP) or filled (using FP) once the polygon
mode has been left (PM2). The pen location at the time PM0 is issued
becomes the first point in the buffer.
Mode 1 closes the polygon defined so far, if not already closed. The next
L
point becomes the first point of the new polygon.
PR (plot relative) ([dxl, dyl, dx2, dy2, . . . . dxn, dyn])
L -
dxl:
x-coordinate of first point
dyl:
y-coordinate of first point etc.
L
This command is the same as PA except that the “pen up” flag is set and no
lines am drawn. If there are no parameters, this is the only effect of the
command.
The coordinates are interpreted as absolute if the command is not preceded
by a PR command, otherwise coordinates are treated as relative.
PU (pen up> ([xl, ~1, ~2, ~2, . . . . xn, ynl>
xl: x-coordinate of first point
yl: y-coordinate of first point etc.
This command is the same as PA except that the “pen up” flag is set and no
lines are drawn. If there is no argument, this is the only effect of the
command.
The coordinates are interpreted as absolute ifthe command was not preceded
by a PR command; otherwise the coordinates are treated as relative.
Pw(pen width) (width (see below) [pen { 1 { 1)
width: clamped real, width of pen in units set by WU
pen: integer, either 0 or 1
The default pen width is 0.35 mm or 1% of the distance Pl to P2. A width of
0 sets the thinnest line possible (one dot).
Metric widths are scaled by the ratio [size of picture frame]/[plot size].
If the pen number is not specified, the new width is applied to both. If neither
pen 0 or 1 is specified, the command is ignored.
This command does not affect the character stroke width, with the exception
of stick characters with stroke weight = 9999.
RA (fill rectangle absolute) (x, y)
x:
x-coordinate of other end of diagonal
Y:
y-coordinate of other end of diagonal
