ccOffsetPolyCurve

ccOffsetPolyCurve(
o_polyCurve           
n_value
[ ?key g_key ]
) 
=> o_polyCurve2

Description

(Virtuoso Photonics Option) Returns a copy of the specified polyCurve that is expanded by the specified offset value.

Arguments

o_polyCurve	ID of a ccPolyCurve object.
n_value	The offset value. A positive offset value implies that the offset direction is to the right, and a negative value implies that it is to the left.
?key g_key	A flag that outputs a polyCurve with "raw" offset when set to a value that is not nil. A "raw" offset polyCurve has cusps, which can be useful for debugging. The default is nil.

Value Returned

o_polyCurve2	ID of the resulting ccPolyCurve.
nil	An error occurred.

Example

arc = ccCreatePolyCurve(list(list(ccCreateCurve("cos(t)" "sin(t)" 0:3.14159265))))

> cc@0xc70cee6c

arc2 = ccOffsetPolyCurve(arc 1)

> cc@0x86ca13ca

; A circle arc of radius 1 gets expanded to an arc of radius 2.

arc2~>beginPt

> (2.0 0.0)

arc2~>endPt

> (-2.0 0.0)
