nine_slice — GFX2D sprite op

• 資料種類:rgba → rgba

• 呼叫:import gfx2d; gfx2d.nine_slice(sprite, left, right, top, bottom, out_height, out_width)(或 opsgfx2d.get("nine_slice"))

用法

把邊框拉伸到新尺寸而不變形四角。

> 以下的詳細說明為原文 —— 摘要與標題已翻譯。

The four corners are copied bit for bit, the four edges are stretched

along one axis only, and the centre is stretched along both. This is the

standard way a UI panel grows: the border keeps its thickness at any size.

Stretching is nearest-neighbour on the interior spans, so an output the same

size as the input is the exact identity — no resampling blur creeps in when

a panel happens not to need stretching.

Raises ValueError: borders that meet or cross (`left + right >= width`),

an output smaller than the borders it must preserve.
