Struct MeshShadingParams 

pub struct MeshShadingParams {
    pub triangles: Vec<ShadingTriangle>,
    pub ctm: Matrix,
    pub bbox: Option<[f64; 4]>,
    pub color_space: ShadingColorSpace,
    pub overprint: bool,

}

Parameters for Gouraud-shaded triangle mesh shading (Types 4 & 5).

New fields may be added without notice; pattern-matching consumers should use .. to ignore unmatched fields.

Fields

triangles: Vec<ShadingTriangle>

ctm: Matrix

bbox: Option<[f64; 4]>

color_space: ShadingColorSpace

overprint: bool

painted_channels: u8

color_lut: Option<Arc<Vec<DeviceColor>>>

Pre-sampled color LUT for function-based mesh shadings. When present, vertex raw_components[0] holds a normalized [0,1] function input. The renderer interpolates this per-pixel, then indexes the LUT instead of Gouraud-interpolating DeviceColor.

alpha: f64

Fill alpha from graphics state (0.0–1.0). Default 1.0.

blend_mode: u8

Blend mode (0=Normal, …, 15=Luminosity). Default 0.

alpha_is_shape: bool

PDF AIS (alpha-is-shape). Default false.

Trait Implementations

impl Clone for MeshShadingParams

fn clone(&self) -> MeshShadingParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MeshShadingParams

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

Formats the value using the given formatter.

impl Default for MeshShadingParams

fn default() -> Self

Returns the “default value” for a type.
