# Quick tester for Dots.OCR debug mode using curl.
#
# Usage examples:
#   scripts/test_debug_ocr.sh -u http://localhost:7860 -f scripts/tom_id_card_front.jpg -d
#   scripts/test_debug_ocr.sh -u https://<your-hf-space>.hf.space -f scripts/tom_id_card_front.jpg -d -r '{"x1":0,"y1":0,"x2":1,"y2":0.5}'
#
# Notes:
# - The `debug` form field enables per-request debug logging on the server.
# - You can also set env DOTS_OCR_DEBUG=1 on the server to enable globally.
