Oxygen XML Editor 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-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.
