RoDraw

RoDraw draws straight onto your screen, over anything. Slides, a browser, a PDF, code — whatever is in front of the class.

What it does

• Draw and write in colour — pen, highlighter, lines, arrows, rectangles, ellipses and text, in eight colours you can change. Double-click a swatch to mix your own with a gradient picker and a hex box.
• Zoom into a region — drag a box and it fills the screen, so the back row can read it. Scroll to move around, Ctrl+scroll to change the magnification. It only magnifies the monitor you drew the box on.
• Sleep mode — one press of F8 and RoDraw gets out of the way completely. Your drawings stay on screen, but every click goes to the program underneath. Press it again to carry on.
• Spotlight and laser pointer — dim everything except one circle, or just point. Clicks still reach your apps, so you can scroll the page you are pointing at.
• Per-monitor — choose which screens RoDraw draws on and leave the others completely alone, so you can read your notes on the second one.
• Whiteboard / blackboard, save or copy the screen with your annotations, and every shortcut is rebindable.

Languages

Requirements

Windows 10 or 11, 64-bit. Installs for a single user by default, so it needs no administrator password — handy on a school machine.

Free, and staying that way

RoDraw is free and open source (GPL-3.0). The code is at https://github.com/111Rosko/RoDraw — read it before you trust it.

Nobody can take it, close it up and sell a proprietary version: the licence obliges anyone who passes it on to hand over the source too. The name and the icons are mine, so a fork has to go by another name.

If it has saved you an afternoon and you would like to send something back, donations are welcome — rosko437@gmail.com. Entirely optional; the program does not nag, count or check.
