When the node "ConditioningSetArea" is combined with the Controlnet node, the coordinate problem

I found that when the node "ConditioningSetArea" is combined with the Controlnet node, I want the left screen content to take the image on the left side of the controlnet, and the right screen content to take the right screen image, so the width of my two "ConditioningSetArea" nodes are both uploaded images Half the width, one x coordinate starts from zero, and one x coordinate starts from half the width of the uploaded image. As a result, the left and right sides of the final image are taken from the same area of the uploaded image, and what I want is that the uploaded image is taken from each side of the left and right sides. Half of it, how do I implement this function
