### rect()

#### Description

Draws a rectangle to the screen. A rectangle is a four-sided shape with every angle at ninety degrees. By default, the first two parameters set the location of the upper-left corner, the third sets the width, and the fourth sets the height. The way these parameters are interpreted, however, may be changed with the rectMode() function.

To draw a rounded rectangle, add a fifth parameter, which is used as the radius value for all four corners.

To use a different radius value for each corner, include eight parameters. When using eight parameters, the latter four set the radius of the arc at each corner separately, starting with the top-left corner and moving clockwise around the rectangle.

#### Examples

• ``````size(400, 400);
rect(120, 80, 220, 220);
``````
• ``````size(400, 400);
rect(120, 80, 220, 220, 28);``````
• ``````size(400, 400);
rect(120, 80, 220, 220, 12, 24, 48, 72);``````

#### Syntax

• `rect(a, b, c, d)`
• `rect(a, b, c, d, r)`
• `rect(a, b, c, d, tl, tr, br, bl)`

#### Parameters

• `a``(float)`x-coordinate of the rectangle by default

• `d``(float)`height of the rectangle by default
• `r``(float)`radii for all four corners
• `tl``(float)`radius for top-left corner
• `tr``(float)`radius for top-right corner
• `br``(float)`radius for bottom-right corner
• `bl``(float)`radius for bottom-left corner

#### Return

• `void`
