Struct TextLayer 

pub struct TextLayer {
    pub text: String,
    pub zones: Vec<TextZone>,
}

The complete text layer of a DjVu page.

Fields

text: String

Full plain-text content of the page, UTF-8.

zones: Vec<TextZone>

Top-level zone nodes (usually a single Page zone).

Implementations

impl TextLayer

pub fn transform( &self, page_w: u32, page_h: u32, rotation: Rotation, render_w: u32, render_h: u32, ) -> Self

Return a copy of this text layer with all zone rectangles transformed to match a rendered page of size render_w × render_h.

• page_w, page_h — native page dimensions from the INFO chunk.
• rotation — page rotation from the INFO chunk.
• render_w, render_h — the pixel size of the rendered output.

Applies rotation first (in native pixel space), then scales the result proportionally to the requested render size. The text content is preserved unchanged.

pub fn reflowable_text(&self) -> Vec<Paragraph>

Group the page text into reading-order paragraphs (#228).

Uses the DjVu zone separator characters carried in self.text:

• \x00 (NUL), \x0b (VT), \x1d (GS), \x1f (US) — paragraph / region / column / page boundary. Each starts a new Paragraph.
• \x0a (LF) — line break within a paragraph.

Line joining: trailing whitespace is dropped from each line. If a line ends with - and the next line starts with an ASCII lowercase letter, the hyphen is dropped and the lines are joined with no separator (soft-hyphen at line end). Otherwise lines are joined with a single ASCII space.

Empty paragraphs (only whitespace) are skipped. The returned vector preserves zone-stream order — for the typical OCR’d single-column page this is reading order.
