}

A block of text extracted from a page.

Fields

text: String

The extracted text content.

page: u32

The page number (1-based).

bbox: [f64; 4]

Bounding box [x0, y0, x1, y1] in PDF coordinates.

font_name: String

Font resource name (e.g. “F1”) — preserved for backward compatibility.

font_size: f64

Font size in points.

actual_text: Option<String>

/ActualText override from a surrounding marked-content sequence (BDC), if any. PDF/UA-compliant authors use this to provide the canonical reading-order text for ligatures or other glyph clusters whose visual text does not match the intended characters.

base_font: Option<String>

BaseFont of the active font dict with any 6-character subset prefix stripped (e.g. Helvetica-Bold). None when the font dict has no BaseFont entry or could not be resolved.

is_bold: bool

Inferred bold style. Set when any of:

• FontDescriptor /FontWeight >= 700
• FontDescriptor /Flags ForceBold bit (bit 19) is set
• the (subset-stripped) BaseFont name contains “bold”, “demi”, “semibold”, “heavy”, or “black”

is_italic: bool

Inferred italic style. Set when any of:

• FontDescriptor /Flags Italic bit (bit 7) is set
• the BaseFont name contains “italic”, “oblique”, or “slant”

color: Option<[u8; 4]>

Active non-stroking fill color as sRGB RGBA at the moment the show operator emitted this block. None for color spaces we cannot map without rendering (ICC, Lab, Pattern, Separation, DeviceN).

width_source: WidthSource

Whether glyph widths were measured from real font advance data or estimated.

char_bounds: Vec<[f64; 4]>

Per-glyph bounding boxes in PDF user-space coordinates, one entry per source glyph (not per Unicode scalar — ligatures count as one). [x0, y0, x1, y1] where y0 < y1 (PDF coordinate system, y increasing up).

Trait Implementations

impl Clone for TextBlock

fn clone(&self) -> TextBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextBlock

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

Formats the value using the given formatter.

impl Default for TextBlock

fn default() -> TextBlock

Returns the “default value” for a type.
