Expand description

A backend that can recover content the deterministic core cannot.

Required Methods§

Source

fn ocr_page(&self, page_png: &[u8], dpi: u32) -> Result<Vec<Char>, BackendError>

OCR a rasterized page (PNG at dpi) into positioned characters.

Source

fn detect_table( &self, region_png: &[u8], ) -> Result<Vec<Vec<Cell>>, BackendError>

Recognize the cell structure of a borderless-table region (PNG).

In older versions of Rust, dyn compatibility was called "object safety".
