  • Then I believe you need to look for some third-party API that provides functionality to scan images and provides OCR functionality. If you still need to do it yourself, then this is not a trivial task and you would need to read about how OCR works and would come up with some algorithm for it. It is not just about extracting text, it is about how to convert what you see on a paper into actual text representation.

  • You should be more specific. If it is an image file, then it is not a text, it is binary file.

  • Do you need to build software that converts scanned image into text you just need to extract some text data from that image? In a second case I believe you need to use software during scanning that convert scanned image into text and then read that text from the file.
