Whiteboard Drawing App

Pro Whiteboard App

 

Core Features

  • Touch Support: Uses touch-action: none and specific touch event listeners to allow seamless drawing on mobile devices without the page scrolling.

  • Dual Modes: Easily toggle between a Brush and an Eraser. The eraser uses destination-out composite operations to actually remove pixels rather than just "painting white."

  • Smooth Lines: Uses lineCap = 'round' and lineJoin = 'round' to prevent jagged edges during fast movements.

  • Responsive Scaling: The resizeCanvas function ensures the canvas always fits its container, even if the user rotates their phone or resizes the window.

  • Ad Integration: Includes a responsive header slot. Note that for drawing apps, placing ads at the very top or very bottom is best to prevent accidental clicks while drawing.
