Python - sRGB to Linear / Linear to sRGB

A quick note to just so I can keep track of the functions.

def srgb2lin(s):
    if s <= 0.0404482362771082:
        lin = s / 12.92
    else:
        lin = pow(((s + 0.055) / 1.055), 2.4)
    return lin


def lin2srgb(lin):
    if lin > 0.0031308:
        s = 1.055 * (pow(lin, (1.0 / 2.4))) - 0.055
    else:
        s = 12.92 * lin
    return s

Note that I picked up these functions somewhere on stackoverflow, I didn’t come up this any of it…
