Box & Crop Studio
Upload an exam sheet once, then choose how to get crop regions: run the box detector, paste a crops JSON, or let a QR code drive the layout. All paths end in the same extracted crop images.
Backendunknown
1. Upload sheet
Works with a single-page photo or a multi-page PDF. For PDFs we show the filename instead of an inline image preview.
2. Choose crop source
Pick how the crop rectangles are defined. You can switch between modes without re-uploading the file.
Box detector
The backend aligns the page and finds horizontal box groups via /box/detect. You can inspect the JSON and then crop using the same definition.
Run the detector to inspect the crop JSON the backend generates.
3. Extracted crops
Any of the modes above will populate this section with one or more pages of crops.
Nothing extracted yet. Run a crop operation first.
