Struct Paint 

pub struct Paint { /* private fields */ }

绘图参数，控制路径的填充/描边及描边样式。 Paint - controls fill/stroke style and stroke parameters for path rendering.

用于 get_fill_path 将路径转换为描边后的填充路径（类似 StrokeRec，但包含 Style）。 Used with get_fill_path to convert path to stroked fill path (like StrokeRec, but includes Style).

Implementations

impl Paint

pub fn new() -> Self

创建默认绘图参数（填充样式）。Creates default paint (fill style).

pub fn set_fill(&mut self)

设置为填充样式。Sets to fill style.

pub fn set_stroke(&mut self, enable: bool)

设置为描边样式。Sets to stroke style.

pub fn set_style(&mut self, style: PaintStyle)

设置绘图样式。Sets paint style.

pub fn set_stroke_width(&mut self, width: f32)

设置描边宽度。Sets stroke width (0 = hairline).

pub fn set_stroke_miter(&mut self, miter: f32)

设置 Miter 限制。Sets miter limit for sharp corners.

pub fn set_stroke_cap(&mut self, cap: StrokeCap)

设置线端样式。Sets line cap.

pub fn set_stroke_join(&mut self, join: StrokeJoin)

设置转角连接样式。Sets line join.

pub fn get_fill_path(&self, path: &Path) -> Option<Path>

将路径转为填充等效路径。 Converts path to filled equivalent (applies stroke/style).

Fill 样式返回原路径副本；Stroke 样式返回描边后的填充路径。 Fill style returns copy of path; stroke style returns stroked fill path.
