Fields

ctm: Matrix

color: DeviceColor

color_space: ColorSpace

path: PsPath

current_point: Option<(f64, f64)>

clip_path: Option<PsPath>

clip_path_version: u32

line_width: f64

line_cap: LineCap

line_join: LineJoin

miter_limit: f64

dash_pattern: DashPattern

flatness: f64

stroke_adjust: bool

overprint: bool

smoothness: f64

default_ctm: Matrix

clip_stack: Vec<Option<PsPath>>

current_font: Option<PsObject>

root_font: Option<PsObject>

page_device: Option<EntityId>

screen_freq: f64

screen_angle: f64

screen_proc: Option<PsObject>

color_screen: Option<[(f64, f64, PsObject); 4]>

Per-component color screen: [red, green, blue, gray] × (freq, angle, proc)

halftone: Option<PsObject>

Halftone dictionary (set by sethalftone)

transfer_function: Option<PsObject>

color_transfer: Option<[PsObject; 4]>

Per-component transfer: [red, green, blue, gray]

sampled_transfer: Option<Arc<Vec<f64>>>

Pre-sampled transfer function (256 entries). None = identity.

sampled_color_transfer: Option<[Option<Arc<Vec<f64>>>; 4]>

Pre-sampled per-component transfer [R, G, B, Gray].

precomputed_halftone: Option<Arc<HalftoneScreen>>

Pre-computed halftone screen for PDF output. None = default (suppressed).

precomputed_color_halftone: Option<[Option<Arc<HalftoneScreen>>; 4]>

Pre-computed per-component halftone [R, G, B, Gray] (from setcolorscreen).

black_generation: Option<PsObject>

undercolor_removal: Option<PsObject>

sampled_black_generation: Option<Arc<Vec<f64>>>

Pre-sampled black generation function (256 entries, domain [0,1] → range [0,1]).

sampled_ucr: Option<Arc<Vec<f64>>>

Pre-sampled undercolor removal function (256 entries, domain [0,1] → range [-1,1]).

color_rendering: Option<PsObject>

rendering_intent: u8

Rendering intent: 0=RelativeColorimetric, 1=AbsoluteColorimetric, 2=Perceptual, 3=Saturation. Default is RelativeColorimetric.

current_pattern: Option<u32>

Index into Context.pattern_store for the active tiling pattern.

pattern_underlying_color: Option<DeviceColor>

Underlying color for uncolored (PaintType 2) patterns.

current_pattern_dict: Option<EntityId>

The pattern dictionary installed by setpattern (or by setcolor in a Pattern color space). PLRM 4.9.6 makes the pattern part of the current color, so currentcolor has to hand the same object back.

pattern_components: Vec<f64>

Components of the underlying color for an uncolored (PaintType 2) pattern, in the Pattern space’s base color space. Empty for colored patterns; currentcolor pushes these ahead of the pattern dictionary.

bbox: Option<[f64; 4]>

tint_values: Option<Vec<f64>>

Tint values from the most recent setcolor (for Separation/DeviceN). 1 value for Separation, N values for DeviceN. None for device color spaces.

cached_tint_table: Option<Arc<TintLookupTable>>

Cached pre-sampled tint lookup table for the current Separation/DeviceN color space. Set when setcolorspace installs a Separation/DeviceN space.

fill_opacity: f64

Constant fill opacity (PDF ca). Range [0,1]. Default 1.0.

stroke_opacity: f64

Constant stroke opacity (PDF CA). Range [0,1]. Default 1.0.

blend_mode: u8

Blend mode index. 0=Normal, 1=Multiply, …, 15=Luminosity. Default 0.

alpha_is_shape: bool

Alpha-is-shape flag (PDF AIS). Default false.

text_knockout: bool

Text knockout flag (PDF TK). Default true.
