The ODT export backend supports literal examples (see Literal Examples) with full fontification. Internally, the ODT export backend relies on ‘htmlfontify.el’ to generate the style definitions needed for fancy listings. The auto-generated styles get ‘OrgSrc’ prefix and inherit colors from the faces used by Emacs Font Lock library for that source language.
For custom fontification styles, customize the
org-odt-create-custom-styles-for-srcblocks option.
To turn off fontification of literal examples, customize the
org-odt-fontify-srcblocks option.
