« SVG Attribute reference home

The creator of SVG content might want to provide a hint about what tradeoffs to make as the browser renders text. The text-rendering attribute provides these hints.

As a presentation attribute, it also can be used as a property directly inside a CSS stylesheet, see css text-rendering for further information

Usage context

Categories Presentation attribute
Value auto | optimizeSpeed | optimizeLegibility | geometricPrecision | inherit
Animatable Yes
Normative document SVG 1.1 (2nd Edition)
auto
Indicates that the browser shall make appropriate tradeoffs to balance speed, legibility and geometric precision, but with legibility given more importance than speed and geometric precision.
optimizeSpeed
Indicates that the user agent shall emphasize rendering speed over legibility and geometric precision. This option will sometimes cause some browsers to turn off text anti-aliasing.
optimizeLegibility
Indicates that the browser shall emphasize legibility over rendering speed and geometric precision. The user agent will often choose whether to apply anti-aliasing techniques, built-in font hinting or both to produce the most legible text.
geometricPrecision
Indicates that the browser shall emphasize geometric precision over legibility and rendering speed. This option will usually cause the user agent to suspend the use of hinting so that glyph outlines are drawn with comparable geometric precision to the rendering of path data.

Example

<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg"
   version="1.1" width="660" height="40"
   text-rendering="optimizeLegibility">
  <link xmlns="http://www.w3.org/1999/xhtml" href='http://fonts.googleapis.com/css?family=Sofadi+One' rel='stylesheet' type='text/css' />
  <style>
      text {font: 30px 'Sofadi One', cursive;}
  </style>
  <g>
    <text y="30">The quick brown fox jumps over the lazy dog.</text>
  </g>
</svg>

optimizeLegibility (first) и geometricPrecision (second)
text-rendering=optimizeLegibility
text-rendering=geometricPrecision

Similarly acts css text-rendering

<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg"
   version="1.1" width="660" height="40">
  <link xmlns="http://www.w3.org/1999/xhtml" href='http://fonts.googleapis.com/css?family=Sofadi+One' rel='stylesheet' type='text/css' />
  <style>
      text {
            font: 30px 'Sofadi One', cursive;
            text-rendering: optimizeLegibility;
         }
  </style>
  <g>
    <text y="30">The quick brown fox jumps over the lazy dog.</text>
  </g>
</svg>
