Struct ClipperOffset 

pub struct ClipperOffset { /* private fields */ }

Path offset (inflate/shrink) engine. Direct port from ClipperOffset class (clipper.offset.h / clipper.offset.cpp).

Inflates (or shrinks) both open and closed paths using the specified join type and end type. After building the raw offset, a Clipper64 union is used to clean up self-intersections.

Implementations

impl ClipperOffset

pub fn new( miter_limit: f64, arc_tolerance: f64, preserve_collinear: bool, reverse_solution: bool, ) -> Self

Create a new ClipperOffset with the given parameters. Direct port from ClipperOffset constructor (clipper.offset.h line 85-91).

pub fn new_default() -> Self

Create a new ClipperOffset with default parameters. miter_limit = 2.0, arc_tolerance = 0.0, preserve_collinear = false, reverse_solution = false.

pub fn error_code(&self) -> i32

Get the error code from the last operation.

pub fn miter_limit(&self) -> f64

Get the miter limit.

pub fn set_miter_limit(&mut self, miter_limit: f64)

Set the miter limit.

pub fn arc_tolerance(&self) -> f64

Get the arc tolerance.

pub fn set_arc_tolerance(&mut self, arc_tolerance: f64)

Set the arc tolerance. Needed for rounded offsets. See offset_trigonometry2.svg.

pub fn preserve_collinear(&self) -> bool

Get the preserve_collinear flag.

pub fn set_preserve_collinear(&mut self, preserve_collinear: bool)

Set the preserve_collinear flag.

pub fn reverse_solution(&self) -> bool

Get the reverse_solution flag.

pub fn set_reverse_solution(&mut self, reverse_solution: bool)

Set the reverse_solution flag.

pub fn set_delta_callback(&mut self, cb: Option<DeltaCallback64>)

Set the delta callback for variable offset. Direct port from ClipperOffset::SetDeltaCallback.

pub fn add_path(&mut self, path: &Path64, jt: JoinType, et: EndType)

Add a single path with the given join type and end type. Direct port from ClipperOffset::AddPath (clipper.offset.cpp line 168-171).

pub fn add_paths(&mut self, paths: &Paths64, jt: JoinType, et: EndType)

Add multiple paths with the given join type and end type. Direct port from ClipperOffset::AddPaths (clipper.offset.cpp line 173-177).

pub fn clear(&mut self)

Clear all groups and normals. Direct port from ClipperOffset::Clear (clipper.offset.h line 98).

pub fn execute(&mut self, delta: f64, paths: &mut Paths64)

Execute the offset operation, storing results in paths. Direct port from ClipperOffset::Execute(double, Paths64&) (clipper.offset.cpp line 636-642).

pub fn execute_tree(&mut self, delta: f64, polytree: &mut PolyTree64)

Execute the offset operation, storing results in a PolyTree64. Direct port from ClipperOffset::Execute(double, PolyTree64&) (clipper.offset.cpp line 645-653).

pub fn execute_with_callback( &mut self, delta_cb: DeltaCallback64, paths: &mut Paths64, )

Execute using a delta callback for variable offset. Direct port from ClipperOffset::Execute(DeltaCallback64, Paths64&) (clipper.offset.cpp line 655-659).
