				EAWUnsubmitted Done Inline Actions Comments should always start with a capital letter and end with a full stop. this program converts an input color to an output value. I could understand this description being used (for example) to describe the RGB to BW operation, where 3 input channels are combined into a single value output channel. I don't see how it accurately describes the SetAlphaMultiply operation, unless I am misunderstanding something, which I do admit is quite possible. 😊 it assumes we are in sRGB color space. It does? Why? Should it? Doesn't this go against the rest of the compositor assuming a linear space? EAW: [Comments should always start with a capital letter and end with a full stop.](https://wiki.
