Struct OcrEngine

pub struct OcrEngine { /* private fields */ }

The OcrEngine struct represents the OneOcr processing engine.

Implementations

impl OcrEngine

pub fn new() -> Result<Self, OneOcrError>

Creates a new instance of the OCR engine. This function loads the necessary library and initializes the OCR pipeline.

pub fn get_max_recognition_line_count(&self) -> Result<i64, OneOcrError>

Retrieves the maximum number of lines that can be recognized. Default is 100.

pub fn set_max_recognition_line_count( &self, count: i64, ) -> Result<(), OneOcrError>

Sets the maximum number of lines that can be recognized. Default is 100, range is 0-1000.

pub fn get_resize_resolution(&self) -> Result<(i64, i64), OneOcrError>

Retrieves the maximum internal resize resolution.

The resize resolution defines the maximum dimensions to which an image will be automatically scaled internally before OCR processing. It’s a performance and accuracy trade-off rather than a restriction on the original image’s resolution.

Default is 1152*768.

pub fn set_resize_resolution( &self, width: i64, height: i64, ) -> Result<(), OneOcrError>

Sets the maximum internal resize resolution.

The resize resolution defines the maximum dimensions to which an image will be automatically scaled internally before OCR processing. It’s a performance and accuracy trade-off rather than a restriction on the original image’s resolution.

The maximum resolution is 1152*768.

pub fn run( &self, image_path: &Path, word_level_detail: bool, ) -> Result<OcrResult<'_>, OneOcrError>

Run the OCR pipeline on the given image path.

impl Drop for OcrEngine

fn drop(&mut self)
