is the average between the original value and the swapped value). Add variants perform
an RGB Add effect after the swap, with the appropriate parameters. Multiply variants
perform an RGB Multiply effect after the swap, with appropriate parameters. Invert in-
verts the final result.
Key effects: One or more keys are either implicitly defined (black, white) or specified.
Pixels with values that match the key are set to transparent. There are both soft and
hard thresholds for each key. If multiple keys are part of an effect, a value must match
all the keys. If difference of a value from the key is above the hard threshold, the value
does not match the key. If it is below the soft threshold, it matches the key. If it is between
the thresholds, it is linearly interpolated between the soft and hard thresholds. Invert
inverts the final result. Mask applies the key, and then makes all remaining color in the
image black.
