Displays only a portion of the Image.
A Filled Image will display a section of the Sprite, with the rest of the RectTransform left transparent. Image.fillAmount will determine how much of the Image to show, and Image.fillMethod controls the shape in which the Image will be cut.
This can be used for example to display circular or linear status information such as timers, health bars, and loading bars.
