Detailed Description

2d profile offset

offset2d is a special 2d operation used for inflating or shrinking a 2d shape,
optionally creating rounded corners and chamfers.

Constructor & Destructor Documentation

offset2d() [1/2]

offset2d::offset2d	(	const shape2d@	profile,
		double	r = 0x7fc00000,
		double	delta = 0x7fc00000,
		bool	chamfer = false
	)

Compute 2d offset for a 2d profile.

Parameters

profile	shape2d@, 2d profile to be offset
r	double, radius if rounded offset required (cannot be combined with delta)
delta	double, straight offset if sharp corners required (cannot be combined with r)
chamfer	bool, true if sharp corners to be chamfered (relevant with delta only)

offset2d() [2/2]

offset2d::offset2d	(	array< shape2d@>@	arr,
		double	r = 0x7fc00000,
		double	delta = 0x7fc00000,
		bool	chamfer = false
	)

Compute 2d offset for an array of 2d shapes.

Parameters

arr	array@, array of 2d shapes to be offset
r	double, radius if rounded offset required (cannot be combined with delta)
delta	double, straight offset if sharp corners required (cannot be combined with r)
chamfer	bool, true if sharp corners to be chamfered (relevant with delta only)
