Text Drawing

The <svg> component can also be used to draw text.

Text

NOTE - The text content must be written in the <text> area. The <tspan> child element label can be nested.

<text> can be nested only by the parent element label svg.

Only the default font sans-serif is supported.

Set the following attributes to define text styles: x (X coordinate), y (Y coordinate), dx (x-axis offset of the text), dy (y-axis offset of the text), fill (font fill color), stroke (text border color), and stroke-width (text border width).

<!-- xxx.hml -->
<div class="container">
  <svg>
    <text x="200" y="300" font-size="80px" fill="blue" >Hello World</text>    <text x="200" y="300" dx="20" dy="80" font-size="80px" fill="blue" fill-opacity="0.5" stroke="red" stroke-width="2">Hello World</text>
    <text x="20" y="550" fill="#D2691E">
      <tspan dx="40" fill="red" font-size="80" fill-opacity="0.4">Hello World </tspan>
    </text>
  </svg>
</div>

Drawing Text Along the Path

Set textpath to draw text along the path.

<!-- xxx.hml -->
<div class="container">
  <svg fill="#00FF00" x="100" y="400">
    <path d="M40,360 Q360,360 360,180 Q360,20 200,20 Q40,40 40,160 Q40,280 180,180 Q180,180 200,100" stroke="red" fill="none"></path>
      <text>
        <textpath fill="blue" startOffset="20%" path="M40,360 Q360,360 360,180 Q360,20 200,20 Q40,40 40,160 Q40,280 180,180 Q180,180 200,100" font-size="30px">
          This is textpath test.
        </textpath>
      </text>
  </svg>
</div>
