Alpha image loose color

[YouGroove]

The image is not colored when it is drawn on screen.

 

Here is my PostRender code :

 

if self.drawAttack then
 context:SetBlendMode(Blend.Alpha)
 local posX = math.floor((context:GetWidth() - self.imageAttack:GetWidth()))/2
 local posY = math.floor((context:GetHeight() - self.imageAttack:GetHeight()))/2
 context:DrawImage(self.imageAttack, posX, posY)
 context:SetBlendMode(Blend.Solid)
end

Maybe you need to call context:SetColor(1,1,1,1) before drawing?
