Usage 🥳

To utilize the OCR module for text extraction, follow these steps:

1. Import the OCR module in your code:

   import { compare } from 'ocr';

2. Call the compare function, passing the image file as an argument. The file variable is expected to be an object with the following properties:

   • originalname: The original name of the file as provided by the client when uploading.

   const file = /* Your image file object */;
      
   try {
     const ocrResults = await compare(file);
     console.log('OCR Results:', ocrResults);
   } catch (error) {
     console.error('OCR Error:', error);
   }
