  一个元素代表一个SVG矩形。通过这个元素你可以画出不同宽度,不同高度,以及不同描边和不同填充颜色的矩形。同时它还可以绘制直角或圆角的矩形。

  一个SVG矩形的简单例子

  下面是一个绘制SVG矩形的简单例子。


  1.    
  2.         style="stroke:#006600; fill: #00cc00"/>

  3.       
复制代码

  SVG矩形的位置由x和y属性决定。请记住,这个位置是相对于任何它最接近的父元素的位置。

  SVG矩形的尺寸由width和height属性决定。

  style属性允许你为矩形设置附加的样式,如描边色,描边宽度和填充色等。

  下面的图形是上面代码的返回结果:

  圆角矩形

  我们也可以绘制圆角的SVG矩形。rx和ry属性用于决定矩形圆角的大小。rx属性决定圆角的宽度,ry属性则决定圆角的高度。下面的例子中,三个矩形的圆角分别被设置为5像素、10像素和15像素,请注意观察他们各自圆角的大小变化。


  1.    
  2.           rx="5" ry="5"
  3.           style="stroke:#006600; fill: #00cc00"/>
  4.    
  5.           rx="10" ry="10"
  6.           style="stroke:#006600; fill: #00cc00"/>
  7.    
  8.           rx="15" ry="15"
  9.           style="stroke:#006600; fill: #00cc00"/>
  10.    
复制代码

  上面的代码的返回结果如下:

3.jpg

  上面的例子中,三个圆角矩形的rx和ry值都是相同的。如果你单独设置了rx的值,那么ry的值和rx相同。这是定义SVG圆角矩形的简写方式。

  下面的两个例子中,rx的值都设置为10像素,但是ry的值分别设置为5像素和15像素。这两个例子展示了矩形圆角的宽度和高度不相同时的情况。


  1.    
  2.           rx="10" ry="5"
  3.           style="stroke:#006600; fill: #00cc00"/>
  4.    
  5.           rx="10" ry="15"
  6.           style="stroke:#006600; fill: #00cc00"/>
  7.    
复制代码

  上面的代码的返回结果如下:

  描边矩形

  你可以使用stroke属性来设置SVG矩形的边框属性。下面的例子设置矩形的边框为绿色,边框的宽度为3像素。
  1.       style="stroke: #009900;
  2.              stroke-width: 3;
  3.              fill: none;
  4.       "
  5.       />      
复制代码

  上面的代码的返回结果如下:

5.jpg

  你还可以使用stroke-dasharray属性将矩形的边框设置为虚线。看下面的例子:
  1.       style="stroke: #009900;
  2.              stroke-width: 3;
  3.              stroke-dasharray: 10 5;
  4.              fill: none;
  5.             "
  6.         />      
复制代码

  上面的代码的返回结果如下:

  填充矩形

  你可以使用fill属性来为SVG矩形填充颜色。例如将矩形的颜色填充为none。
  1.       style="stroke: #009900;
  2.              fill: none;
  3.             "
  4.         />         
复制代码

  这时,SVG矩形的填充色将和浏览器的页面颜色一样。

7.jpg

  你也可以选择一种颜色来填充矩形。下面的例子将矩形填充为绿色。
  1.       style="stroke: #009900;
  2.              fill: #33ff33;
  3.             "
  4.         />     
复制代码
8.jpg
  最后,你可以用fill-opacity属性来设置填充矩形的透明度。下面的例子中,两个句子部分叠加在一起,上面的矩形设置为50%的填充透明度。
  1.       style="stroke: #009900;
  2.          fill: #33ff33;
  3.         "
  4.         />
  5.       style="stroke: #000099;
  6.          fill: #3333ff;
  7.          fill-opacity: 0.5;
  8.         "
  9.         />            
复制代码

  上面的代码的返回结果如下:
