}

Parameters for a text element emitted by show operators.

The PDF device uses these for BT/ET/Tf/Tj text operators. The raster device ignores them (uses Fill elements for glyph paths).

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

Fields

text: Vec<u8>

Character bytes (or 2-byte CID values for Type 0).

start_x: f64

Device-space X position at start of string.

start_y: f64

Device-space Y position at start of string.

font_entity: u32

Font dict entity ID (raw u32 for VM independence).

font_name: Vec<u8>

FontName bytes (e.g., b“Times-Roman“).

font_type: i32

FontType (0, 1, 2, 3, 42).

font_size: f64

Effective device-space font size.

color: DeviceColor

Fill color at render time.

ctm: [f64; 6]

CTM at render time.

font_matrix: [f64; 6]

User-space font matrix (scaled to point units).

paint_type: i32

PaintType: 0 = fill (default), 2 = stroke (outlined glyphs).

stroke_width: f64

Device-space stroke width for PaintType 2 fonts.

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.

fill_opacity: f64

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

stroke_opacity: f64

Stroke opacity (0.0–1.0, default 1.0). Applies to PaintType-2 fonts.

blend_mode: u8

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

alpha_is_shape: bool

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

text_knockout: bool

Text knockout (PDF TK). Default true.

Trait Implementations

impl Clone for TextParams

fn clone(&self) -> TextParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextParams

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

Formats the value using the given formatter.

impl Default for TextParams

fn default() -> Self

Returns the “default value” for a type.
