Implementations

impl TextLine

pub fn value(&self) -> String

Concatenated text value of all chunks, inserting spaces between chunks when a horizontal gap indicates a word boundary.

Whitespace-only chunks are skipped (matching the reference processTextLines which skips isWhiteSpaceChunk() chunks); word spaces are re-detected from bounding-box gaps via needs_space().

For letter-spaced text (≥70% of chunks are single-character), an adaptive gap threshold based on the median inter-chunk gap is used instead of the fixed fontSize * 0.17 rule. This correctly collapses text like "H O W C A N" into "HOW CAN".

pub fn concatenate_chunks(chunks: &[TextChunk]) -> String

Concatenate a slice of owned TextChunks using gap-based word boundary detection. Handles letter-spaced text with adaptive threshold.

For multi-line content (e.g. table cells), chunks on different visual lines are separated by spaces — detected via Y-position change.

pub fn chunk_count(&self) -> usize

Number of text chunks in this line.
