📖 How to use Tesselize
Step 1 — Load an image
Click Upload image for a photo, or Open Tess file for a built-in tessellation (click a name) or a saved .tess (Browse). Load demo image tries the maple leaf. Best results come from subjects with clean, simple outlines and a plain background.

Step 2 — Select your subject
Click Auto-detect objects (server), then click the yellow box around your subject to segment it. Use Add / Erase / Wand to refine the selection. Important: erase any background clutter (fences, shadows, ground) — artifacts cause the tessellation to fail.

Step 6 — Warp to fit curves
Click Warp Shape to Fit Curves! This clips your shape to a boundary the tiling can repeat with no gaps (expect some squashing; it does not add new interlocking bumps). If the tile disappears, your image has artifacts — go back to Step 3 and erase them.
