# ellipseMode()

By default, the **x** and **y** inputs refer to the center of the ellipse.

This can be changed using `ellipseMode()`, with an input of **CENTER**, **CORNERS**, **CORNER**, or **RADIUS**.

#### ellipseMode(CENTER)

This is the default mode. The code:

```python
ellipse(x, y, width, height)
```

will use **(x,y)** as the center coordinates and **width** and **height** as the dimensions.

#### ellipseMode(CORNERS)

This mode is for specifying the coordinates of opposite corners of the ellipse's bounding box. The code:

```python
ellipse(x1, y2, x2, y2)
```

#### ellipseMode(CORNER)

This mode is for specifying the **corner** of the ellipse's bounding box together with the **width** and **height**. The code:

```python
ellipse(x, y, width, height)
```

will use **(x,y)** as the bottom left corner of the ellipse's bounding box and **width** and **height** as the dimensions.

#### ellipseMode(RADIUS)

This mode is for specifying the **center** of the ellipse together with **half the width** and **half the height**. The code:

```python
ellipse(x, y, wRadius, hRadius)
```

will use **(x,y)** as the center coordinates and **wRadius \* 2** and **hRadius \* 2** as the dimensions.
