Parameters for filling a path.

Constructed by interpreter/parser code (stet-ops, stet-pdf-reader) and read by renderers. New fields may be added without notice; pattern- matching consumers should use .. to ignore unmatched fields.

Fields

color: DeviceColor

fill_rule: FillRule

ctm: Matrix

is_text_glyph: bool

True when this fill is a text glyph from a show operator. PDF device skips these (uses Text elements instead).

overprint: bool

Overprint flag from graphics state (used by PDF output).

overprint_mode: i32

Overprint mode (0 or 1). With OPM 1 + DeviceCMYK, only non-zero channels are painted.

opm_paired: bool

True when /OPM was set together with /op or /OP in the same ExtGState dict that configured this fill. Enables strict OPM-1 “preserve zero components” behavior; when false, an all-zero CMYK source still performs a full knockout (legacy Adobe compatibility).

painted_channels: u8

Which CMYK channels this fill paints (bitmask of CMYK_C/M/Y/K).

is_device_cmyk: bool

True when color space is DeviceCMYK or ICCBased(4).

spot_color: Option<SpotColor>

Separation/DeviceN color for PDF output. None for device color spaces.

rendering_intent: u8

Rendering intent (0=RelativeColorimetric, 1=Absolute, 2=Perceptual, 3=Saturation).

transfer: TransferState

Pre-sampled transfer function state for PDF output.

halftone: HalftoneState

Pre-computed halftone screen state for PDF output.

bg_ucr: BgUcrState

Pre-sampled black generation / undercolor removal for PDF output.

alpha: f64

Fill opacity (0.0–1.0, default 1.0). Used by PDF transparency.

blend_mode: u8

Blend mode (0=Normal, 1=Multiply, …, 11=Exclusion). Default 0.

alpha_is_shape: bool

PDF AIS (alpha-is-shape). When true, the source is interpreted as shape rather than opacity. Default false.

Trait Implementations

impl Clone for FillParams

fn clone(&self) -> FillParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FillParams

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

Formats the value using the given formatter.

impl Default for FillParams

fn default() -> Self

Returns the “default value” for a type.
