PropTypeDefaultDescription
propsnullnullThe exported CropperControlledDemo component does not declare or accept props.
Accessibility
- The image provides the alternative text "Landscape".
- Each slider has an associated Label through a generated useId-based id and htmlFor pair.
- The zoom and rotation values are exposed in the visible labels and update as the sliders change.
- The reset control contains only an icon and has no accessible name in the source; add an aria-label such as aria-label="Reset crop" when using or adapting this demo.
- The cropper image uses crossOrigin="anonymous", which supports canvas-based image processing when the remote image permits it.
