Lumia Scroll Capture

Companion extension for the Lumia desktop app — captures full-page scrolling screenshots with exact pixel offsets.

Lumia Scroll Capture takes full-page, scrolling screenshots of any web page and sends them to the Lumia desktop app on the same computer for stitching, annotation, and saving. Because the extension reads the page's real scroll offsets from the DOM, the stitched result has none of the seams, duplicated bars, or drift you get from screen-scrape scrolling tools. WHAT YOU CAN CAPTURE • Visible area — just what's currently on screen (one frame). • Full page — scroll the whole page (or an app's inner scroll pane) and stitch it into one tall image, keeping the header and sidebar chrome instead of cropping them away. • Select area — pick any element on the page (a d-pad / arrow keys walk the DOM tree: parent, child, siblings) and capture exactly that box. HOW IT WORKS The extension scrolls the page in exact viewport steps, photographs each step, and streams the frames with their precise offsets to the Lumia desktop app, which composites them. A small on-page status bar shows progress and lets you stop early and keep what's captured so far. REQUIRES THE LUMIA DESKTOP APP This extension is a companion to the Lumia desktop application and does nothing on its own — install and run Lumia first. When the app is running, a green dot appears on the extension's toolbar icon. PRIVACY Captured images are sent only to the Lumia app running on your own machine, over a local (127.0.0.1) connection. Nothing is uploaded to the developer, to any server, or to third parties. No analytics, no tracking.
