Re: [docbook-apps] admon graphics: GIF vs PNG

Hello Mike and all:

If you want to work with optional extensions for admonition graphics,
the $admon-graphic$  definition should be as it appears in the dbparam
file located in the "print" subdirectory. Here is it:

(define ($admon-graphic$ #!optional (nd (current-node)))
  ;; REFENTRY admon-graphic
  ;; PURP Admonition graphic file
  ;; DESC
  ;; Given an admonition node, returns the name of the graphic that should
  ;; be used for that admonition.
  ;; /DESC
  ;; AUTHOR N/A
  ;; /REFENTRY
  (cond ((equal? (gi nd) (normalize "tip"))
     (string-append %admon-graphics-path%
            (string-append "tip"
                       admon-graphic-default-extension)))
    ((equal? (gi nd) (normalize "note"))
     (string-append %admon-graphics-path%
            (string-append "note"
                       admon-graphic-default-extension)))

    ((equal? (gi nd) (normalize "important"))
     (string-append %admon-graphics-path%
            (string-append "important"
                       admon-graphic-default-extension)))

    ((equal? (gi nd) (normalize "caution"))
     (string-append %admon-graphics-path%
            (string-append "caution"
                       admon-graphic-default-extension)))
    ((equal? (gi nd) (normalize "warning"))
     (string-append %admon-graphics-path%
            (string-append "warning"
                       admon-graphic-default-extension)))
    (else (error (string-append (gi nd) " is not an admonition.")))))

I don't know why the definition in the "html" subdirectory is different (it
uses the "gif" extension only.

Puts that definition in you customizing parameters file.

Hope this helps.
