2 <p>The Font Settings API allows you to manage Chrome's font settings.</p>

3 <h2 id="manifest">Manifest</h2>

4 <p>The Font Settings API is currently experimental, so you must declare the

5 "experimental" permission to use it. For example:</p>

6 <pre>{

7 "name": "My Font Settings Extension",

8 "description": "Customize your fonts",

9 "version": "0.2",

10 "permissions": ["experimental"]

11 }</pre>

12 <h2 id="scripts">Generic Font Families and Scripts</h2>

13 <p>Chrome allows for some font settings to depend on certain generic font

14 families and language scripts. For example, the font used for sans-serif

15 Simplified Chinese may be different than the font used for serif Japanese.</p>

16 <p>The generic font families supported by Chrome are based on

17 <a href="http://www.w3.org/TR/CSS21/fonts.html#generic-font-families">CSS generi c font families</a>

18 and are listed in the API reference below. When a webpage specifies a generic

19 font family, Chrome selects the font based on the corresponding setting. If no

20 generic font family is specified, Chrome uses the setting for the "standard"

21 generic font family.</p>

22 <p>When a webpage specifies a language, Chrome selects the font based on the

23 setting for the corresponding language script. If no language is specified,

24 Chrome uses the setting for the default, or global, script.</p>

25 <p>The supported language scripts are specified by ISO 15924 script code and

26 listed in the API reference below. Technically, Chrome settings are not strictly

27 per-script but also depend on language. For example, Chrome chooses the font for

28 Cyrillic (ISO 15924 script code "Cyrl") when a webpage specifies the Russian

29 language, and uses this font not just for Cyrillic script but for everything the

30 font covers, such as Latin.</p>

31 <h2 id="examples">Examples</h2>

32 <p>The following code gets the standard font for Arabic.</p>

33 <pre>

34 chrome.experimental.fontSettings.getFont(

35 { genericFamily: 'standard', script: 'Arab' },

36 function(details) { console.log(details.fontName); }

37 );

38 </pre>

39 <p>The next snippet sets the sans-serif font for Japanese.</p>

40 <pre>

41 chrome.experimental.fontSettings.setFont(

42 { genericFamily: 'sansserif', script: 'Jpan', fontName: 'MS PGothic' }

43 );

44 </pre>

45 <p>You can find a sample extension using the Font Settings API in the

46 <a href="http://src.chromium.org/viewvc/chrome/trunk/src/chrome/common/extension s/docs/examples/api/fontSettings/">examples/api/fontSettings</a>

47 directory. For other examples and for help in viewing the source code, see
