FT - Fill type
FT [ n [, d [, q]]] [;]
n : Fill type
d : Fill interval (interval between the parallel lines of the area being filled)
q : Fill angle (degrees )
Sets the fill type, interval and angle when filling an area.
The value for n is a clamped integer number.
Solid lines (bi-directional fill)
Solid lines (single direction fill)
Parallel lines
Crosshatching
The fill interval when n is 1 or 2 is the interval set by the pen thickness (PT) instruction.
Any value given for d when n is 1 or 2 will be ignored.
If d is omitted, the fill interval already specified will be used.
If d is 0, the default value will be used ( 1% of distance from P1 to P2. )
The value of d is a clamped real number.
If q is omitted, the fill angle already specified will be used.
The value of q is a clamped real number.
LT - Line type selection
LT [, n [, p ]] [;]
n ; Line pattern number
p ; Line pattern length (percentage or millimeters of distance between P1 and P2)
Specifies the line type and pattern length.
When the n parameter field is omitted a solid line is selected.
When the p parameter field is omitted the pattern length is 4% of the distance between P1 and P2 (default
value ).
The value of
n
is a clamped integer number.
The value of
p
is a clamped real number from 0.0000 to 127.9999.
When
p
is omitted the previously set line pattern length is used.
Default
:Solid
line
:For straight line, start and end points are plotted.
:For an arc, plotting takes place for every chord angle that is set.
