sprite scaling problem

Hi guys, I am trying to move a sprite around when I click on a inventory item and then put it back into the slot.
The problem I am having is that when I pick up the inventory sprite, its massive on the screen.
I need to be able to scale it properly but I just cant seem to get it to work. Here is the code.


//The hoverObject's position
Vector2 position;

//Translates the mouse screen position inot a local position and stores it in the position
RectTransformUtility.ScreenPointToLocalPointInRectangle(canvas.transform as RectTransform, Input.mousePosition, canvas.worldCamera, out position);


//Adds the offset to the position
position.Set(position.x, position.y - hoverYOfset);

//Sets the hoverObjects position
hoverObject.transform.position = canvas.transform.TransformPoint(position);

here is another example of the same function.

float xm = Input.mousePosition.x;
float ym = Input.mousePosition.y;

hoverObject.transform.position = new Vector2(xm + 1, ym + 1);

Any suggestions??
