Per-glyph SDF rendering effects that can be applied in the fragment shader.

Fields

outline: bool

Whether to render an outline.

outline_color: Vec4

Outline color (RGBA).

outline_width: f32

Outline width in SDF-space units (0.0 to ~0.2).

shadow: bool

Whether to render a drop shadow.

shadow_color: Vec4

Shadow color (RGBA).

shadow_offset: Vec2

Shadow offset in screen pixels.

shadow_softness: f32

Shadow softness (blur radius in SDF-space, 0.0 to ~0.2).

glow: bool

Whether to use the distance field as a glow source.

glow_color: Vec4

Glow color (RGBA).

glow_radius: f32

Glow radius in SDF-space (how far from edge the glow extends).

bold: bool

Bold mode: shifts the threshold to make glyphs thicker.

wave_amplitude: f32

UV distortion effects: wave, shake, glitch.

wave_frequency: f32

shake_amount: f32

glitch_intensity: f32

Implementations

impl SdfEffects

pub fn none() -> Self

No effects — plain SDF rendering.

pub fn outline(color: Vec4, width: f32) -> Self

Outline only.

pub fn shadow(color: Vec4, offset: Vec2, softness: f32) -> Self

Drop shadow only.

pub fn glow(color: Vec4, radius: f32) -> Self

Glow only.

pub fn bold() -> Self

Bold text.

pub fn wave(amplitude: f32, frequency: f32) -> Self

Wavy text animation.

pub fn glitch(intensity: f32) -> Self

Glitch effect.

Trait Implementations

impl Clone for SdfEffects

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SdfEffects

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

Formats the value using the given formatter.

impl Default for SdfEffects

fn default() -> Self

Returns the “default value” for a type.
