# rectMode()

By default, the **x** and **y** inputs refer to the bottom left corner of the rectangle.

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

#### rectMode(CORNER)

This is the default mode. The code:

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

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

#### rectMode(CORNERS)

This mode is for specifying the coordinates of opposite corners. The code:

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

will use **(x1,y1)** as the bottom left corner coordinates and **(x2,y2)** as the top right (diagonally opposite) corner coordinates.

#### rectMode(CENTER)

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

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

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

#### rectMode(RADIUS)

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