ColorCurve

app.command.ColorCurve {
  ui=true,
  channels=FilterChannels...,
  curve={ Point, Point, Point... }
}

ui: Shows the dialog on the screen, true by default. Set to false to apply the color curve filter automatically without asking to the user for the change.
channels: A combination of FilterChannels with bitwise OR (|) operator. By default it is equal to: FilterChannels.RED | FilterChannels.GREEN | FilterChannels.BLUE | FilterChannels.GRAY.
curve: Array of points where X is the input value and Y the output value.

Example

app.command.ColorCurve {
  ui=true,
  channels=FilterChannels.RED,
  curve={ { 0, 0 }, { 255, 128 } }
}
