rect()矩形

Name

rect()矩形

Examples

rect(30, 20, 55, 55);

rect(30, 20, 55, 55, 7);

rect(30, 20, 55, 55, 3, 6, 12, 18);

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.

在屏幕上绘制一个矩形。矩形是一个四棱形, 每个角度为九十度。默认情况下, 前两个参数设置左上角的位置, 第三个设置宽度, 第四设置高度。但是, 这些参数的解释方式可能会随 rectMode () 函数而改变。

若要绘制圆角矩形, 请添加第五参数, 它用作所有四角的半径值。

要对每个角使用不同的半径值, 请包括八参数。当使用八参数时, 后四分别设置每个角上的圆弧半径, 从左上角开始, 在矩形周围顺时针移动
