💡 Why V11 is the best: Wu's anti-aliased line drawing in the canvas simulation matches how SVG renderers actually draw lines. This eliminates the canvas↔SVG gap that plagued V10. Combined with 350 pins (vs 300), more lines (5685 vs 3489), and iterative line replacement, V11 achieves +14.4% SSIM improvement over V10.
Version Comparison
V11 (new best) vs V10 (previous best). V11 has significantly better contrast, sharper details, and more recognizable features.

V11 Algorithm Details
- Wu's Anti-Aliased Lines: Fractional pixel coverage matching SVG renderer behavior
- Source-Over Compositing: canvas[px] *= (1 - α × coverage), per-pixel Wu coverage
- Calibrated Alpha (0.15): Matched to SVG stroke-width 0.12mm for optimal SSIM
- Multi-Start Greedy: 3 starting pins, picks best result
- Iterative Replacement: 2 passes replacing each line with better alternatives
- Line Removal: Removes lines that hurt quality after greedy phase
- Importance Map: 60% darkness + 40% edges, center-weighted Gaussian
- Parallel Evaluation: 8 workers for fast candidate scoring
- Adaptive Stopping: Detects quality plateau, jumps to high-error regions
