Frequently Asked Questions
How does the Online Whiteboard work?
The whiteboard uses an HTML Canvas element that captures pointer events (mouse, touch, and stylus). Each stroke records a series of (x, y) coordinates which are drawn as connected line segments using the Canvas 2D API's lineTo() and stroke() methods. Brush size sets the lineWidth, and color sets the strokeStyle. The stroke history is stored in an array for undo support, and the canvas can be exported as a PNG via canvas.toDataURL().
Can I save my drawings?
Yes. You can download your whiteboard drawing as an image file. The canvas state is also preserved in your browser between sessions.
Does it work with a stylus or tablet?
Yes. The whiteboard responds to mouse, touch, and stylus input. It works on tablets and touchscreen devices for a natural drawing experience.
Can I undo a mistake?
Yes. Use the undo feature to step back through your drawing history. You can also use the eraser tool to remove specific areas.
