anchor.diff:    background_image: title-cover.png
   ----
   
  +In this case, the image is resolved relative to theme directory.
  +
   Here's how the image is specified using the inline image macro:
   
   [source,yaml]
  
positive.code: title_page:
    background_image: image:title-cover.png[]
  ----
  
  Like in the AsciiDoc syntax, the inline image macro allows you to supply set the width of the image and the alignment:
  
  
negative.code: . `<face>` can be `front` or `back`.
  . The path is resolved relative to base_dir.
  . The target of the image macro is resolved relative to `imagesdir`.
  If the image macro syntax is not used, the value is resolved relative to the base directory, which defaults to the document directory.
  . Page background images are automatically scaled to fit within the bounds of the page.

  NOTE: Page backgrounds do not currently work when using AsciidoctorJ PDF.
