Useful next steps
Only completely empty margins
The crop box includes every pixel whose alpha is not zero. Even a barely visible pixel remains. Transparent areas inside the crop box stay in place.
An empty image stays empty
If every source pixel is transparent, the tool returns a transparent pixel and marks the image as empty in its report. Padding applies to nonempty images.
