fullpath. Full name of file from server's root directory
^file:fullpath[filename]
Retrieves full name of file from server's root directory (see also "Appendix 1: Paths to files and directories").
Example: page /document.html contains a link to some image. True path to the requested document, however, may be different (e.g. if you use module mod_rewrite on Apache web-server). In this case, if you place a relative link to the image, the image will not be displayed by browser, since browser has no idea about mod_rewrite and will regard all relative paths as relative to the requested document.
That is why it is better to replace relative path with absolute:
$image[^image::measure[^file:fullpath[image.gif]]]
^image.html[]
Construction…
<img src="/image.gif" width="…" height="…" />
…will result in code containing absolute path.
