When to Crop the Stamp Area?

Cropping is optional — the full image works out of the box. Crop the stamp area when the stamp is small, when the page contains other colored elements (logos, highlights, colored text), or when you want the algorithm to focus only on the region you care about. The cropped area is used exactly as you set it, with no automatic padding.
