🛠️ Troubleshooting

No Pixel Value Retrieved

If you're having trouble retrieving a pixel value, ensure you've clicked on a valid point within the image boundaries. Points outside of the image will result in errors.

Image Not Displaying

Ensure that the input image is correctly connected. If there is no image, the input cannot be processed, and thus clicking won't yield any output.
