Shape barcode engine — transforms a standard Code 128 barcode into a shaped barcode with two rendering styles:

Styles

:silhouette (animals, objects)

Solid filled silhouette (head, ears, tail, legs) with barcode bars placed inside a rectangular region within the body. Like a cookie-cutter: the animal is solid, the barcode is the "window" inside it.

:contour (geometric, abstract)

Bars with variable heights following a top/bottom contour, with optional decorations (circles, polygons, lines).

Output

All coordinates are normalized to a 0.0–1.0 bounding box so any renderer (PDF, SVG, Canvas) can scale to the desired size.
