Preview drawing a tile shape
tiled_preview_shapeRead-only
Rasterize a deterministic geometric shape (line, rectangle, ellipse) into tile cells and return a mapEdit change set for preview.
Instructions
Rasterizes one deterministic geometric shape — a Bresenham line, a rectangle outline or fill, or a midpoint ellipse inscribed in its bounding rectangle — into exact tile cells and returns an ordinary mapEdit change set carrying the setTiles writes. Pure bounded computation: no randomness, no clipping (a shape that leaves the map fails closed), at most 10,000 cells, and a null tile erases along the shape. Every preview, revision-pin, and transaction rule applies unchanged.
