Struct FocalData

pub struct FocalData {
    pub fr1: f32,
    pub f_focal_x: f32,
    pub f_is_swapped: bool,
}

Focal data for a radial gradient.

Fields

fr1: f32

The normalized radius of the outer circle in focal space.

f_focal_x: f32

The x-coordinate of the focal point in normalized space [0,1].

f_is_swapped: bool

Whether the focal points have been swapped.

Implementations

impl FocalData

pub fn create(r0: f32, r1: f32, matrix: &mut Affine) -> Self

Create a new FocalData with the given radii and update the matrix.

pub fn is_focal_on_circle(&self) -> bool

Whether the focal is on the circle.

pub fn is_swapped(&self) -> bool

Whether the focal points have been swapped.

pub fn is_well_behaved(&self) -> bool

Whether the gradient is well-behaved.

pub fn is_natively_focal(&self) -> bool

Whether the gradient is natively focal.

Trait Implementations

impl Clone for FocalData

fn clone(&self) -> FocalData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FocalData

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

Formats the value using the given formatter.

impl PartialEq for FocalData

fn eq(&self, other: &FocalData) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
