light op• 資料種類:rgb × rgb → rgb
• 呼叫:import gfx2d; gfx2d.light_mask(base, light, ambient=0.0)(或 opsgfx2d.get("light_mask"))
用 `rgb 光照圖調變 rgb 影像:base * (ambient + light)`。
> 以下的詳細說明為原文 —— 摘要與標題已翻譯。
`ambient is the light that reaches everything; ambient=1` with a black
light map returns the base exactly, which is the identity the test suite
pins.
The product is clipped to `[0, 1]`; the clipped amount is not returned.
Both arguments should be in the same encoding — mixing an sRGB base with a
linear light map is the second silent-error trap of this family, and the
only defence is that both arguments are named.
