Type Rendering Mix

Bower version devDependency Status

Type Rendering Mix website

Type Rendering Mix detects your browser’s text rasterizer and antialiasing method by parsing the user agent string. It will then add two classes to your HTML element. One class will describe the text rasterizer and the other the antialiasing method it is using:

<html class="tr-coretext tr-aa-subpixel">

The text rasterizer class name can take the following values:

  • tr-coretext for OS X and iOS;
  • tr-gdi for Windows XP and Windows Vista SP1;
  • tr-directwrite for Windows Vista SP2 and above;
  • tr-freetype for Android and Linux.

The antialiasing method class name will be one of the following:

  • tr-aa-none when no antialiasing is applied;
  • tr-aa-grayscale when grayscale antialiasing is applied;
  • tr-aa-subpixel when subpixel antialiasing is applied.

If Type Rendering Mix can’t determine the antialiasing method with absolute certainty it will attempt to guess. In this case unknown will be added to the class name:

  • tr-aa-unknown-none when no antialiasing is guessed;
  • tr-aa-unknown-grayscale when grayscale antialiasing is guessed;
  • tr-aa-unknown-subpixel when subpixel antialiasing is guessed.

When it is impossible to determine or guess the text rasterizer and antialiasing method tr-unknown and tr-aa-unknown will be used to indicate an unknown text rasterizer and antialiasing method.
