Screen OCR

The screen-ocr package makes it easy to perform OCR on portions of the screen.

Installation

Choose one of the following backends and follow the steps. WinRT is recommended for Windows and Tesseract for all other platforms.

WinRT

WinRT is a Windows-only backend that is very fast and reasonably accurate. To install screen-ocr with WinRT support, run pip install screen-ocr[winrt]

Tesseract

Tesseract is a cross-platform backend that is much slower and slightly less accurate than WinRT. To install screen-ocr with Tesseract support:

  1. Install Tesseract binaries. For Windows, see https://github.com/UB-Mannheim/tesseract/wiki.
  2. pip install screen-ocr[tesseract]

EasyOCR

EasyOCR is a very accurate but slow backend and only runs on Python 64-bit, and hence is considered experimental. To install screen-ocr with WinRT support, run pip install screen-ocr[easyocr]

Usage

You can do a simple test by running python -m screen_ocr to OCR the current screen contents. See __main__.py for the code.

If using Tesseract with a custom installation directory on Windows, set tesseract_data_path and tesseract_command paths appropriately when constructing a Reader instance.

See also gaze-ocr for more a more involved usage example.
