Rendering buffer to HTML from command line script |

Hello,
I'm trying to create a command line Emacs script that, by specifying a file
and a theme, renders the file to HTML using the theme colours.
For example:
emacs --script render-theme.el some-theme.el test.c > test.c.html
I'm using htmlfontify to render the buffer to HTML, and works great when
called from X, but I get a black and white output when called from the
terminal _with most themes_.
The problem is that themes specify the minimum terminal requirements to
enable a specific face, i.e. minimum amount of colours supported by the
terminal, window-system, etc. (
http://www.gnu.org/software/emacs/manual/html_node/elisp/Defining-Faces.html
)
For example: (defface 'foo (((min-colors 88) (class color) etc.))
If I modify the theme to disable these terminal requirements options,
htmlfontify renders correctly.
That's probably a long shot, but is it possible to either force a
particular terminal configuration from command line, or force-enable all
theme faces?
For example, (display-color-cells) in X returns 16777216, while I get 0
when executed from the script; that's probably part of the problem.
Why am I doing this: I want to create an Emacs theme browser web
application which creates a preview of any theme against a few different
file formats, and I want an headless Emacs to create the HTML preview.
Thanks.
Stephane.
