	})
	
function Create()
	InGain = self:AddInput("Gain", "Gain", {
		LINKID_DataType = "Number",
		INPID_InputControl = "SliderControl",
		INP_Default = 1.0,
		})
 
	InImage = self:AddInput("Input", "Input", {
		LINKID_DataType = "Image",
		LINK_Main = 1,
		})
 
	OutImage = self:AddOutput("Output", "Output", {
		LINKID_DataType = "Image",
		LINK_Main = 1,
		})				
		
end
 
function Process(req)
	local img     = InImage:GetValue(req)
	local gain    = InGain:GetValue(req).Value
