VideoTransferFunction.encode

double encode(gstvideo.types.VideoTransferFunction func, double val)

Convert val to its gamma encoded value.

For a linear value L in the range [0..1], conversion to the non-linear (gamma encoded) L' is in general performed with a power function like:

L' = L ^ (1 / gamma)

Depending on func, different formulas might be applied. Some formulas encode a linear segment in the lower range.

Parameters

funca #GstVideoTransferFunction
vala value

Returns

the gamma encoded value of val
