Extracting text from an image: Experiments with Shape Detection
I built a Progressive Web App (PWA) that extracts text from images shared to it. It uses the Share Target API to receive images, the Shape Detection API's TextDetector to analyze them, and EXIF-Js to handle image rotation issues. While it's a handy tool, it currently suffers from cross-browser and cross-version compatibility problems due to the lumpy nature of the web platform. The code snippets highlight key implementation details, like manifest setup, service worker handling, text extraction, and image rotation.
