This repo contains code for generating debugging visualizations for the Tesseract OCR engine. It is a JavaScript-based alternative to the Java GUI program found in the ScrollView directory in the Tesseract repo. Generate debugging visualizations at with your own images at debug.scribeocr.com.

Please note: this code requires a modified version of Tesseract/Tesseract.js to run, and is currently only usable within scribeocr.com, the Scribe.js library, and the website linked above. Please thumbs-up this issue if you have interest in better integration with the main Tesseract program, and we can look into this if there is enough demand.

To run the included website (debug.scribeocr.com) yourself locally, simply run a web server from this directory. Below is an example using http-server.

npx http-server

To use the example, visit the URL indicated, which is usually localhost:8080.
