 flood-color="" flood-opacity=""/>

用法:

，-它定义了用户坐标系中的x轴和y轴坐标。
宽度-外部对象的宽度。
高度-foreignObject的高度。
flood-color-告诉新层的颜色。
flood-opacity-告诉新层的不透明度值。

范例1：

<!DOCTYPE html>

    <svg width="200" height="200"> 
        <defs> 
            <filter id="filter1" 
                filterUnits="userSpaceOnUse"> 
                  
                <feFlood x="5%" y="5%" width="198" 
                height="118" flood-color="shadow" 
                flood-opacity="0.3" /> 
            </filter> 
        </defs> 
  
        <rect x="1" y="1" width="198" 
            height="118" style="stroke:#000000; 
                         fill:red;  
                         filter:url(#filter1);" /> 
  
        <g fill="#FFFFFF" stroke="Green"
