SVG <feFlood> Element
  • Last Updated : 27 Oct, 2020

SVG stands for Scalable Vector Graphic. It can be used to make graphics and animations like in HTML canvas. SVG <feFlood> element generates a layer of continuous color that completely fills this element’s filter primitive region.

Syntax:

<feFlood x="" y="" width="" height=""
 flood-color="" flood-opacity=""/>

Syntax:

  • x, y – It defines the x-axis, and y-axis coordinate in the user coordinate system.
  • width – The width of the foreignObject.
  • height – The height of the foreignObject.
  • flood-color – It tells the color of the new layer.
  • flood-opacity – It tells the opacity value of the new layer.

Example 1:




<!DOCTYPE html>
<html>
  
<body>
    <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" 
            font-size="20" font-family="Verdana">
            <text x="28" y="70">GeeksForGeeks</text>
        </g>
    </svg>
</body>
  
</html>
