The ODT export back-end supports literal examples (see Literal Examples) with full fontification. Internally, the ODT export back-end 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.
