Image Data Hook (pro use)

You can use the function window.__ipyturtle_get_image_data to get turtle panel drawing result.

const crop = false; // Set true to auto crop to contents
window.__ipyturtle_get_image_data(crop).then(data => {
    console.log(data); // image buffer
    // to base64
    // const base64String = btoa(String.fromCharCode(...new Uint8Array(buffer)));
})
