Examples |
rectMode(CORNER); // Default rectMode is CORNER fill(255); // Set fill to white rect(25, 25, 50, 50); // Draw white rect using CORNER mode
rectMode(CORNERS); // Set rectMode to CORNERS fill(100); // Set fill to gray rect(25, 25, 50, 50); // Draw gray rect using CORNERS mode
rectMode(RADIUS); // Set rectMode to RADIUS fill(255); // Set fill to white rect(50, 50, 30, 30); // Draw white rect using RADIUS mode
rectMode(CENTER); // Set rectMode to CENTER fill(100); // Set fill to gray rect(50, 50, 30, 30); // Draw gray rect using CENTER mode |

Description |
Modifies the location from which rectangles are drawn by changing the way in which parameters given to rect() are intepreted. The default mode is rectMode(CORNER), which interprets the first two parameters of rect() as the upper-left corner of the shape, while the third and fourth parameters are its width and height. rectMode(CORNERS) interprets the first two parameters of rect() as the location of one corner, and the third and fourth parameters as the location of the opposite corner. rectMode(CENTER) interprets the first two parameters of rect() as the shape’s center point, while the third and fourth parameters are its width and height. rectMode(RADIUS) also uses the first two parameters of rect() as the shape’s center point, but uses the third and fourth parameters to specify half of the shapes’s width and height. The parameter must be written in ALL CAPS because Processing is a case-sensitive language. 通过更改给矩形 () intepreted 的参数的方式, 来修改从其绘制长方形的位置。
默认模式为 rectMode (角), 它将矩形 () 的前两个参数解释为形状的左上角, 而第三和第四参数是其宽度和高度。
rectMode (角) 将矩形 () 的前两个参数解释为一个角的位置, 第三和第四参数作为相对角的位置。
rectMode (中心) 将矩形 () 的前两个参数解释为形状的中心点, 而第三和第四参数是其宽度和高度。
rectMode (radius) 还使用矩形 () 的前两个参数作为形状的中心点, 但使用第三和第四参数指定形状的宽度和高度的一半。
该参数必须以所有大写形式写入, 因为处理是一种 case-sensitive 的语言。 |
