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 according 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 following keywords are recognized:

passive=(yes|no)
Cause the image to be displayed in a manner similar to an ordinary 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.
menu=(yes|no)
Enable or disable the pop-up menu. The pop-up menu is enabled by default.
keyboard=(yes|no)
Enable or disable the DjVu plugin keyboard shortcuts. The default is yes (enabled).
frame=(yes|no)
Enable or disable the display of a thin gray frame around the DjVu image. Keyboard shortcuts are enabled by default.
links=(yes|no)
Enable or disable hyper-links in the DjVu image. Hyper-links are enabled by default.

backDisplay the background only.

hor_align=keyword
Specify the horizontal position of the page in the viewer window. (This does not specify what part of the page will be shown, but rather how margins will be laid out around the page in the plugin window.) Argument keyword must be left, center, or right.
ver_align=keyword
Specify the vertical position of the page in the viewer window. (This does not specify what part of the page will be shown, but rather how margins will be laid out around the page in the plugin window.) Argument keyword must be top, center, or bottom.
toolbar=keyword{(,|+|-)keyword}
Controls the appearance and the contents of the toolbar. The argument of option toolbar is composed of a number of keywords separated by characters comma, plus or minus. The appearance of the toolbar is controlled by keywords placed before the first occurrence of a character plus or minus. The following keywords are recognized in this context:
noDisable toolbar.
alwaysDisable toolbar "autohide" mode.
autoEnable toolbar "autohide" mode.
topPlace toolbar along top edge (not implemented).
bottomPlace toolbar along bottom edge.
The contents of the toolbar is controlled by keywords placed after the first occurrence of a character plus or minus. Each keyword adds (after a plus) or remove (after a minus) a particular toolbar button or group of buttons. The initial content of the toolbar is determined by the first occurrence of a character plus or minus. When this is a plus the toolbar is initially empty. When this is a minus the toolbar is initially full. The following keywords are recognized:

The origin is set at the bottom left corner of the image. The color color must be given in hexadecimal RRGGBB format. Omitting the color argument means to use XOR highlighting. Multiple highlighted zone can be specified.

print=(yes|no)
Enable or disable printing the djvu image. Printing is enabled by default.

The same options can be specified as parameters of EMBED or OBJECT tags in a HTML file. See nsdejavu(1) for more details.
