Subject: Re: DOCBOOK-APPS: Images & PDF output

First of all, to get the best, clearest output for images in PDF, we convert our bitmaps and vector images to .pdf files in Adobe Printshop (which allows us to scale them while maintaining excellent resolution, and relatively small file size). We use .eps files for Postscript output, and .gif or ..png for HTML. For processing, we use a trick posted on the DOCBOOK list on 03/01/00 by Angus Lees. Use the <graphic> tag, and put in a fileref="image" without any extension, where "image" can be, for example, image.pdf, image.eps, image.gif, etc. for each format you need. Then, by adding this code to the print stylesheet: .................................................................... (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%)))) ...................................................................... the correct extension is chosen and used automatically. For the HTML stylesheet you can just specify .gif or .png like this: ...................................................................... (define %graphic-default-extension% "gif") ..................................................................... We take this route rather than the more updated <mediaobject>, because the .pdf extension isn't recognized by DocBook 3.1. This route gives us a workaround, since the .pdf extension isn't in the SGML code at all. Hopefully, version 4.0 or 4.1 recognizes .pdf (we haven't checked yet) or at least 5.0 will, because by that time the <graphic> tag will be obsolete, right Norm? --- Bob
