jp_stop_marking_mesh — DRIVE `japan` op

• Data kinds: none → any (an op determined by its arguments alone — it takes no image or data input)

• Call: import fullseye as fs; fs.ledger.jp_stop_marking_mesh(*, char_h: 'float' = 2.4, char_w: 'float' = 0.8, gap: 'float' = 1.0, z: 'float' = 0.007) (to call the implementation directly, import drivejapan; drivejapan.jp_stop_marking_mesh(*, char_h: 'float' = 2.4, char_w: 'float' = 0.8, gap: 'float' = 1.0, z: 'float' = 0.007); from the registry, opsdrive.get("jp_stop_marking_mesh"))

Usage

Road marking text "Tomare" (STOP) (non-statutory marking, white). Local coordinates: origin = lane center at the near end of the character row (the side closer to the car), +x = direction of travel, +y = left.

Dimensions follow figure example (1) of No. 46 of the National Police Agency's "Traffic Regulation Standards" (Japan): each character 240 × 80 cm, stroke 15 cm, horizontal bar 30 cm, character spacing 1 m, in vertical layout from the far side TO · MA · RE ("stop"; the driver reads from the top = the far character is at the top). Per the installation guideline, placed from 1–3 m before the stop line (JP_TOMARE_SETBACK_M). The glyphs are simplified polyline glyphs (curves approximated). Returns (V, F, colors). Raises ValueError: dimensions not positive.
