Re: images in Docbook with Red Hat 6.2

[Sam Roberts <sam at cogent dot ca>]

pdfjadetex need pdf, png, or perhaps jpeg formatted images, it
doesn't grok .eps.

The easy way to fix this is to make the stylesheets not generate
an extension in the tex files (right now there's an option
where you specify the default extension for print, html, rtf, etc.
-- except that the print/tex is going to become two formats,
pdf and ps, so this doesn't work). The code below does this.
[pdf]jadetex then figures out for itself what it's preferred
image format is and finds it (assumming it exists...).

By the way, this list is dead. You should subscribe to the
docbook-apps mailing list, it's very active and helpful. There
should be info on Normans site at www.nwalsh.com. Mail me
if you can't find it.

(define (graphic-file filename)
    (let ((ext (file-extension filename)))
        (if (or tex-backend   ;; TeX can work this out itself
            (not filename)
            (not %graphic-default-extension%)
            (member ext %graphic-extensions%))
        filename
        (string-append filename "." %graphic-default-extension%))))
