Struct ShapeClip 

pub struct ShapeClip {
    pub geometry: ClipGeometry,
    pub transform: Transform,
    pub rule: FillRule,
}

A snapshotted Shape used for geometric intersection, not coverage multiplication.

Fields

geometry: ClipGeometry

Snapshot of the local clipping geometry, not a bounding-box substitute.

transform: Transform

Local mapping in authoring, device mapping in a DisplayList.

rule: FillRule

Interior interpretation of this shape independently of its ancestors.

Implementations

impl ShapeClip

pub fn new(shape: &(impl Shape + ?Sized)) -> Result<Self, ValidationError>

Captures a shape once; trait objects are accepted without retaining them.

Exact rectangles retain raw bounds so invalid rectangles fail validation with the clip. Other shapes share a checked path and report its errors.

use motion_core::prelude::*;
use motion_core::{
    DisplayList, RasterLimits, ResourceStore, ValidatedDisplayList, MAX_PATH_VERBS,
    MAX_STROKE_VERBS, MAX_SVG_PATH_BYTES, sample_offsets,
};
let path = Path2D::from_rect(Rect::new(0.0, 0.0, 1.0, 1.0))?;
let shape: &dyn Shape = &path;
let mut clip = ShapeClip::new(shape)?;
clip.rule = FillRule::EvenOdd;
clip.transform = Transform::translate(0.5, 0.0);
let frame = Node::from(Rect::new(0.0, 0.0, 2.0, 1.0).fill(Color::WHITE))
    .clip_with(clip, motion_core::ClipMode::Geometric)
    .compile(
        Size::new(2.0, 1.0),
        PixelSize::new(2, 1),
        ValidationLimits::default(),
    )?;

pub fn validate(&self, path: &str) -> Result<usize, ValidationError>

Checks geometry and transform, returning the path-verb count for structural charging.
