DocBook to EPUB Transformation

Oxygen XML Developer Eclipse plugin includes a built-in transformation scenario that is designed to convert DocBook content to EPUB. The EPUB specification recommends the use of OpenType fonts (recognized by their .otf file extension) whenever possible. To use a specific font, follow these steps:

1. Declare it in your CSS file, as in the following example:

   @font-face {
   font-family: "MyFont";
   font-weight: bold;
   font-style: normal;
   src: url(fonts/MyFont.otf);
   }

2. In the CSS, specify where this font is used. To set it as default for <h1> elements, use the font-family rule, as in the following example:

   h1 {
   font-size:20pt;
   margin-bottom:20px;
   font-weight: bold;
   font-family: "MyFont";
   text-align: center;
   }

3. Open the Configure Transformation Scenario(s) dialog box, select the DocBook EPUB transformation scenario in the DocBook 4 or DocBook 5 section, and click Edit.
4. In the Parameters tab, set the epub.embedded.fonts parameter to fonts/MyFont.otf. If you need to provide more files, use commas to separate their file paths.
   Note: The html.stylesheet parameter allows you to include a custom CSS in the output EPUB.
5. Run the transformation scenario.
