Implementations§

Source §

impl<'a> LayoutAnalyzer<'a>

Source

pub fn new(doc: &'a LopdfDocument) -> Self

Create a new layout analyzer.

Source

pub fn font_stats_mut(&mut self) -> &mut FontStatistics

Get mutable reference to font statistics (for external use).

Source

pub fn group_spans_into_lines_pub(&self, spans: Vec<TextSpan>) -> Vec<TextLine>

Public wrapper for group_spans_into_lines.

Source

pub fn detect_headings_pub(&self, lines: Vec<TextLine>) -> Vec<TextLine>

Public wrapper for detect_headings.

Source

pub fn group_lines_into_blocks_pub( &self, lines: Vec<TextLine>, ) -> Vec<TextBlock>

Public wrapper for group_lines_into_blocks.

Source

pub fn extract_page_spans(&self, page_num: u32) -> Result<Vec<TextSpan>>
