You can access the plugin's settings from the Typesetting menu (second from the left) in the top menu bar.\n\n\u003cimg src=\"img/bubblezoom_demo_low_v1_1.gif\" width=\"450\"\u003e\n\n*Plugin preview*\n\n\n# Installation\n\nDownload the latest version of the plugin from the [releases](https://github.com/anezih/bubblezoom.koplugin/releases). Copy the `bubblezoom.koplugin` folder to your KOReader installation's `plugins` directory.\n\n\n# Disclosure\n\nI've written and streamlined the image processing workflow (luma calculations, integral images, sauvola thresholding, flood fill and morphological closing) in C# as a PoC. However, I've used ChatGPT codex to create the final lua plugin, as KOReader documentation's drawing and input interception parts are not easy to get into.\n\n# References\n- J. Sauvola and M.
