Show HN: I made an open source desktop magnifier for demo and presentations I wanted a cool magnifier for my presentations, but couldn't find one (the default windows one was not really usable for my case) So I built one using Vue and Tauri (weird stack for such a tool, huh?). It was a pretty fun little project, hope you guys can have some use. Here's how it works: - When you press the shortcut, it takes a screenshot and store it in a temp folder - It then displays an HTML window and passes the screenshot URL to it - The HTML window has no "decorations" (top bar) and only contains an empty div - This div uses the screenshot as a background and updates the background position based on the cursor location - The window location is also updated according to the cursor location using a requestAnimationFrame (so that it does not get triggered too often) - The wheel event impacts the size of the window, as well as a transform:scale on the background. https://github.com/hugoattal/milky-warp May 6, 2023 at 12:44AM
