Note: You have to restart metro-bundler for changes in the babel.config.js file to take effect.

Usage

1. Scan documents with vision camera.

   import { detect } from 'vision-camera-dynamsoft-document-normalizer';
   
   // ...
   const frameProcessor = useFrameProcessor((frame) => {
     'worklet';
     const detectionResults = detect(frame);
   }, []);

2. Scan documents from a file (or use detectBase64).

   let detectionResults = await detectFile(photoPath);

3. Normalize a document image with the detection result (or use normalizeBase64).

   let normalizedImageResult = await normalizeFile(photoPath, detectionResult.location,{saveNormalizationResultAsFile:true});

4. License initialization (apply for a trial license).

   await initLicense("your license");
