Struct ClipperOffset 

pub struct ClipperOffset { /* private fields */ }

Clipper2 path offsetter: inflate or deflate polygons/polylines (integer Path64).

Clipper2 路径偏移器：对 Path64 做膨胀或收缩。

Implementations

impl ClipperOffset

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

Creates an offset engine (miter_limit, arc_tolerance, flags).

创建偏移引擎（斜接上限、圆弧容差、布尔选项）。

pub fn add_path( &mut self, path: &Path64, join_type: JoinType, end_type: EndType, )

Adds one path with join and end types. / 添加单条路径及连接/端点类型。

pub fn add_paths( &mut self, paths: &Paths64, join_type: JoinType, end_type: EndType, )

Adds many paths. / 添加多条路径。

pub fn execute(&mut self, delta: f64) -> LazyPaths64

Runs offset by signed delta (positive = outward for closed paths). / 按有符号 delta 执行偏移。

pub fn clear(&mut self)

Clears queued paths. / 清空已添加路径。

pub fn get_miter_limit(&self) -> f64

Miter limit. / 斜接上限。

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

Sets miter limit. / 设置斜接上限。

pub fn get_arc_tolerance(&self) -> f64

Arc tolerance for rounding. / 圆角弧形容差。

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

Sets arc tolerance. / 设置弧形容差。

pub fn get_preserve_collinear(&self) -> bool

Preserve-collinear flag. / 保留共线顶点。

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

Sets preserve-collinear. / 设置是否保留共线顶点。

pub fn get_reverse_solution(&self) -> bool

Reverse-solution flag. / 反转解。

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

Sets reverse-solution. / 设置是否反转解方向。
