The call could look like

   (apply 'call-process
          tumme-cmd-create-temp-image-program
          nil t nil
          (mapcar
           (lambda (s) (format-spec
                        s
                        (list
                         (cons ?x size-x)
                         (cons ?y size-y)
                         (cons ?f (tumme-quote-bad-characters file))
                         (cons ?t (tumme-quote-bad-characters new-file)))))
           tumme-cmd-create-temp-image-options))

There's no /bin/sh involved, so no interpretation of quotes, so no need
for quoting.
