mosaic_tiles_render — PRINTPATH npr op

• 数据种类:image2d × pairs → image2d

• 调用: import fullseye as fs; fs.ledger.mosaic_tiles_render(image, sites)(要直接调用实现,import printpath; printpath.mosaic_tiles_render(image, sites);从台账取用则 opsprintpath.get("mosaic_tiles_render"))

用法

用各 Voronoi 单元所辖像素的均值来填色。

★Why the mean and not something prettier: for a fixed partition the mean

is the `L2`-optimal constant — no other value lowers the squared error

inside the cell. The tile colour is therefore a solution, not a taste, and any

alternative can be *shown* to be worse by evaluating the same sum.

Returns an `image2d`: the mosaic.

Raises `ValueError`: sites not (N, 2) with N >= 1; sites outside the

image; a non-finite or oversized image.

Limits: cells are convex polygons, so this does not imitate the irregular

tesserae of real mosaic and never runs a single tile along an edge the way a

mosaicist would.
