srgb_to_linear — GFX2D colorspace op

使い方

sRGB-encoded values to linear light (IEC 61966-2-1).

An alpha channel, if present, is not transformed — coverage is already linear. Accepts (H, W), (H, W, 1|3|4).

Use this before anything that adds or scales light (:func:radial_light, :func:light_mask, :func:normal_map_shade, :func:bloom) if the input came out of an image file. Skipping it does not raise: it makes highlights bloom too early and shadows too dark, by the amount quoted in the module docstring.
