ccLayerOffset(
g_shapes
n_value
[ ?cellView d_cellView ]
[ ?lpp g_lpp ]
[ ?facetsToCurves { t | nil } ]
) 
=> l_surfaces

Description

(Virtuoso Photonics Option) Returns a list of surfaces derived by merging the areas of the input shapes and offsetting them by the specified offset value. Resulting surfaces can optionally be created in the specified cellview and with the specified layer-purpose pair different from the default layer-purpose pair of the first input shape.

Arguments

g_shapes	o_shape | (o_shape...) An input shape or a list of input shapes.
n_value	Offset value.
?cellView d_cellView
	Database ID of a cellview.
?lpp g_lpp	tx_layer | (tx_layer tx_purpose) Layer or a layer-purpose pair.
?facetsToCurves t | nil
	Specifies whether all input facets are converted to curves before the actual operation. The default is nil, which means that the input facets are not converted to curves.

Value Returned

l_surfaces

List of resulting surfaces.

Example

c=ccCreateCurve("3*cos(t)" "3*sin(t)" 0:8*atan(1))

> cc@0x36adc1b

s1=ccCreateSurface(cvId "y0" ccCreatePolyCurve(list(c list(0:2 0)) ?close t))

> cc@0x2d609190

s2=ccCreateSurface(cvId "y0" ccCreatePolyCurve(list(c list(-sqrt(3):-1 0)) ?close t))

> cc@0x20480bc0

s3=ccCreateSurface(cvId "y0" ccCreatePolyCurve(list(c list(sqrt(3):-1 0)) ?close t))

> cc@0x29143150

s=ccLayerOffset(list(s1 s2 s3) 0.5)

> (cc@0x2b01d870)
