7-R (tmspa=ncy) ([n I 1 II)
n:
clamped integer
= 0: opaque mode
= 1: transparent mode
-
L
In the transparent mode, white source dots do not change the destination
pixel; in the opaque mode, such dots white out the destination pixel.
Note the similarity to the standard <ESc>*vnN command, but also note that
the opposite meanings of the parameter values. Also, there is no command
corresponding to the standard <ESC>*vnO.
UL (userdefined line type) (index [dash], gap1 [, . . . dash20, gap20]))
- ‘C_
index:
clamped integer, type identifier (1 - 8)
dash, gap:
clamped real, percentage of LT instruction length
L
for type with same index
If the index is negative, its absolute value is used.
Without parameters, this command resets all line types as defined by the LT
command.
i
When only the first parameter is specified, the command resets the line type
as identified by the parameter defined in the LT command.
With more parameters, this command alters the pattern of the same index,
defined by the LT command. A zero dash value yields a point.
If a dash is negative, a gap is not positive, the sum of all dashes and gaps is
0, or the index is 0 or greater than 8, the command is ignored.
WG (wedge fill) (R, start angle, sweep angle, [chord angle (511)
R:
signed radius of the arc of the wedge
start angle:
clamped real, signed start angle
sweep angle: clamped real, signed sweep angle
chord angle:
clamped real, angle subtended by chord, from 0.5 to
180
This command draws a filled wedge (see EW command).
This command clears the polygon buffer and uses the buffer to draw.
WU (unit for pen width) ([type (0)])
type:
0, interpret PW as metric
1, interpret PW as relative (percentage of distance Pl to P2)
. This command selects the unit to be used by PW.
When appmpriate, metric parameters am scaled by the ratio
[size of picture frame]/[plot size]
