Implementations§

Source§

impl OcrEngine

Source

pub fn load(dir: &Path) -> Result<OcrEngine, Box<dyn Error + Send + Sync>>

dir holds pp-ocrv6_small_det.onnx, pp-ocrv6_small_rec.onnx, ppocrv6_dict.txt.

Source

pub fn default_engine() -> Option<OcrEngine>

Resolves via crate::paths (env STEELDB_OCR_DIR → cache → next-to-exe → ./models/ocr); None if the models aren’t present.

Source

pub fn ocr_path( &mut self, path: &Path, ) -> Result<String, Box<dyn Error + Send + Sync>>

Load an image file and OCR it (convenience for callers without the image crate in scope).

Source

pub fn ocr_image( &mut self, img: &RgbImage, ) -> Result<String, Box<dyn Error + Send + Sync>>

OCR one page image → recognized text (reading order: top-to-bottom, left-to-right).
