This example shows a simple text element and two morphology filters applied to the same text. The first filter thins the text with an operator value of erode and a radius value of 1. The second filter thickens the text with an operator value of dilate and and radius value of 1.2.

The image will look like this.

<!DOCTYPE HTML>
<html>
    <head></head>
    <body>
        <svg width="400" height="400">
            <defs>
                <filter id="MyFilter1" filterUnits="userSpaceOnUse" x="50" y="50" width="300" height="300">
                    <feMorphology operator="erode" radius="1"  />
                </filter>
                <filter id="MyFilter2" filterUnits="userSpaceOnUse" x="50" y="50" width="300" height="300">
                    <feMorphology operator="dilate" radius="1.2"  />
                </filter>
            </defs>
            <g font-family="Verdana" font-size="36" stroke="black" stroke-width="2">
                <text x="50" y="50">
                    Unfiltered
                </text>
                <text x="50" y="150" filter="url(#MyFilter1)">
                    Erode
                </text>
                <text x="50" y="250" filter="url(#MyFilter2)">
                    Dilate
                </text>
            </g>
        </svg>
    </body>
</html>
