Struct DistanceField2D 

pub struct DistanceField2D { /* private fields */ }

Negative inside the glyph.

Implementations

impl DistanceField2D

pub fn from_samples( origin: Vec2, cell: f32, samples_x: usize, samples_y: usize, samples: Vec<f32>, ) -> Option<Self>

The caller owns the padded all-outside boundary ring that bake establishes and this does not check.

pub fn samples_mut(&mut self) -> &mut [f32]

Changing samples can invalidate the distance field’s Lipschitz bound.

pub fn sample_counts(&self) -> (usize, usize)

pub fn sample_position(&self, i: usize, j: usize) -> Vec2

pub fn sample(&self, p: Vec2) -> f32

Bilinear contour distance with L2 Lipschitz bound sqrt(2) for samples baked from an exact distance field.

pub fn cell_size(&self) -> f32

Grid spacing in world units.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DistanceField2D

fn fmt(&self, f: &mut Formatter<'_>) -> Result
