Atomic text fragment — one font run in the PDF content stream.

Fields

value: String

Decoded Unicode text content

bbox: BoundingBox

Bounding box in page coordinates

font_name: String

Font name (base font name like “Helvetica”)

font_size: f64

Font size in points (effective, after matrix transforms)

font_weight: f64

Font weight (100.0 - 900.0)

italic_angle: f64

Italic angle from font descriptor

font_color: String

Text color as hex string (e.g. “#000000”)

contrast_ratio: f64

Contrast ratio against background (1.0-21.0)

symbol_ends: Vec<f64>

X-coordinate of each glyph end position

text_format: TextFormat

Text baseline format (normal, superscript, subscript)

text_type: TextType

Text type classification

pdf_layer: PdfLayer

Processing layer that produced this chunk

ocg_visible: bool

Whether the OCG (Optional Content Group) is visible

index: Option<usize>

Global index in extraction order

page_number: Option<u32>

Page number (1-based)

level: Option<String>

Nesting level (from structure tree)

mcid: Option<i64>

Marked content identifier (from BDC/BMC operators in the content stream). Links this chunk to a structure tree node for semantic tagging.

Implementations

impl TextChunk

pub fn is_white_space_chunk(&self) -> bool

Whether the entire text value is whitespace.

pub fn compress_spaces(&mut self)

Collapse consecutive spaces into single space.

pub fn text_length(&self) -> usize

Number of characters in the text.

pub fn average_symbol_width(&self) -> f64

Average width per symbol.

pub fn symbol_start_coordinate(&self, idx: usize) -> f64

Get the X coordinate where the symbol at idx starts.

pub fn symbol_end_coordinate(&self, idx: usize) -> f64

Get the X coordinate where the symbol at idx ends.

Trait Implementations
