ccOrientCurve

ccOrientCurve(
o_curve
S_orient
) 
=> o_outCurve | nil

Description

(Virtuoso Photonics Option) Returns a copy of the specified  ccCurve or ccPolyCurve rotated counterclockwise around the origin by a multiple of 90 degrees after optionally mirroring it across the X-axis or Y-axis. Mirroring also reverses the orientation of the curve.

Arguments

o_curve	ID of a ccCurve or ccPolyCurve object.
S_orient	Transformation specified by rotation angle around (0,0) and optional mirroring across the X-axis or Y-axis. Valid values are "R0", "R90", "R180", "R270", "MY", "MYR90", "MX", "MXR90"

Examples

In this example a straight line curve with equation x(t)=2*t, y(t)=3*t is mirrored and then rotated by 90 degrees counterclockwise around the origin, resulting in a straight line with equation x(t)=-2*t, y(t)=3*t and transformation angle of 90 degrees.
