Scan workflow

⬜ Step 1 — Page fencing: tap the 4 corners of the A4 paper (TL → TR → BL → BR)

⬜ Step 2 — Section A: read roll number ovals

⬜ Step 3 — Section B: read answer ovals (16 cols × 45 rows)

4-Fence Manual Calibration (100% accurate)

Tap 4 corners of each region (Page, Roll, MAT, SAT). Drag any marker afterwards to nudge it onto the exact oval centre. Saved calibration persists across all future scans — set up once, scan many.

Marker: 14px Zoom: 100%

Calibration Helper — 40 anchors total (or 36 with Auto-detect)

🟧 Fence 1 — Page Corners (4)

Tap each round black registration circle OR click 🎯 Auto to detect them automatically.

🟦 Fence 2 — Roll Number (4)

Roll uses bilinear (works perfectly with 4 corners). 7 cols × 10 digits.

🟩 Fence 3 — MAT Q1–90 (16 anchors)

                          MT1 MT2 MT3 MT4 MT5 MT6 MT7 MT8

                           │   │   │   │   │   │   │   │

                          MB1 MB2 MB3 MB4 MB5 MB6 MB7 MB8

Each column tapped twice: TOP + BOT. Per-column lerp = no inner-column drift.
MT1=Q1-O1, MT5=Q46-O1, MB4=Q45-O4, MB8=Q90-O4.

🟪 Fence 4 — SAT Q91–180 (16 anchors)

                          ST1 ST2 ST3 ST4 ST5 ST6 ST7 ST8

                           │   │   │   │   │   │   │   │

                          SB1 SB2 SB3 SB4 SB5 SB6 SB7 SB8

ST1=Q91-O1, ST5=Q136-O1, SB4=Q135-O4, SB8=Q180-O4.

Workflow: Each MAT/SAT column tapped column-by-column: top of col 1, bottom of col 1, top of col 2… If you tap wrong: click "↶ Undo last tap" or "↻ Restart this fence" — only the current fence resets. Drag any marker afterwards to nudge it. After 40 taps, click 🔒 Save & Lock Template — every future scan uses this template automatically (Auto Mode).

Manual grid position (type exact values, watch the dots)

Section B — Answers (16 cols × 45 rows)

First oval X % Option gap % Block pitch % Row top % Row bottom % Sensitivity

Section A — Roll number (7 × 10)

Roll left % Roll right % Roll top % Roll bottom %

All values are % of the corner-box. Type a number, click Apply, and the pink dots move. Goal: every pink dot sits on an oval mid-point. Values persist for this session.
