Struct PatchShadingParams 

pub struct PatchShadingParams {
    pub patches: Vec<ShadingPatch>,
    pub ctm: Matrix,
    pub bbox: Option<[f64; 4]>,
    pub color_space: ShadingColorSpace,
    pub overprint: bool,
    pub painted_channels: u8,
    pub color_lut: Option<Arc<Vec<DeviceColor>>>,
}

Parameters for Coons/tensor-product patch mesh shading (Types 6 & 7).

Fields

patches: Vec<ShadingPatch>

ctm: Matrix

bbox: Option<[f64; 4]>

color_space: ShadingColorSpace

overprint: bool

painted_channels: u8

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

When present, vertex raw_colors[i][0] holds a normalized [0,1] function input. The renderer interpolates this per-pixel, then indexes the LUT for per-pixel non-linear function evaluation.
