Parameters for axial (linear) gradient shading (Type 2).

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

Fields

x0: f64

y0: f64

x1: f64

y1: f64

color_stops: Vec<ColorStop>

extend_start: bool

extend_end: bool

ctm: Matrix

bbox: Option<[f64; 4]>

color_space: ShadingColorSpace

overprint: bool

overprint_mode: i32

PDF OPM (overprint mode). 0 = standard (KO when a component is set); 1 = Illustrator-style (a component explicitly set to 0 is preserved). Must round-trip through PDF→DL→PDF or shadings painted onto an underlay lose their preserved-component behavior.

painted_channels: u8

alpha: f64

Fill alpha from graphics state (0.0–1.0).

blend_mode: u8

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

alpha_is_shape: bool

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

spot_tint_blend: bool

True when this shading uses a Separation/DeviceN color space with a CMYK alternate AND at least one non-process spot colorant. The renderer composites the per-pixel CMYK from the gradient stops with the tracked CMYK buffer multiplicatively, preserving underlying CMYK paints under the gradient (e.g. green checkmarks under a green→cyan DeviceN strip survive).

Trait Implementations

impl Clone for AxialShadingParams

fn clone(&self) -> AxialShadingParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AxialShadingParams

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

Formats the value using the given formatter.

impl Default for AxialShadingParams

fn default() -> AxialShadingParams

Returns the “default value” for a type.
