Isn't continuous? Really? That seems surprising to me; tell me more.
- froh 1y agoit's complicated for appropriate values of complicated. more specifically it's defined piecewise and the standard then rounds some constants in the definition, which results in a slight discontinuity around the transition from one piece to the other. https://en.wikipedia.org/wiki/SRGB#Deriving_the_transfer_function https://en.wikipedia.org/wiki/SRGB#Deriving_the_transfer_fun...
- angra_mainyu 1y agoA piecewise function is definitely not what I'd call "complicated".
- itishappy 1y agoIt's an implementation detail. In theory, it should be continuous.
