What annotation tools are available?

This tool provides three annotation tools: Rectangle (draws a stroked box by clicking and dragging), Arrow (draws a directional line with an arrowhead by clicking start and end points), and Text (places a text label at a clicked position).

Can I undo an annotation?

Yes. Use the Undo button to remove the most recently added annotation. The canvas is re-rendered from the original image each time.

Does the tool support transparent backgrounds?

The annotation layer is rendered directly onto the uploaded image. If your image has a transparent background (PNG), the canvas will show a white background beneath the annotations.
