USING DJVIEW3 AS A BROWSER PLUGIN
The djvulibre browser plugin works by invoking a standalone DjVu viewer
with the special option -netscape. See the man page nsdejavu(1) for
more details.
When djview3 is invoked by the djvulibre browser plugin, a number of
options can be specified as CGI style arguments in document URL accord‐
ing to the following template:
http://server/dir/file.djvu?djvuopts&keyword=value&keyword=value&...
The DjVu browser plugin only recognizes keywords that appear after the
word djvuopts. Unrecognized keywords are silently ignored. The fol‐
lowing keywords are recognized:
passive=(yes|no)

nary web image. The default zoom factor is changed to "Fit
Page". The toolbar, the pop-up menu, the scroll bar, and the
keyboard shortcuts are disabled. The default is no.
scrollbars=(yes|no)
Enable or disable the presence of scroll bars when the full
image size exceeds the plugin window size. The default is yes.

keyword adds (after a plus) or remove (after a minus) a particu‐
lar toolbar button or group of buttons. The initial content of
the toolbar is determined by the first occurrence of a character
