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.
