Parameter Name Omissible Description
superimpose Yes
This function displays a bitmap image as an overlay on the video image. Specify
the image using the “bitmap-filename,x,y” format. Use the GIF format for bitmap
images (transparent GIFs supported). The “x,y” parameters specify the coordinates
of the bitmap image position on the video frame. If “x,y” is omitted, the image is
displayed in the center of the video frame.
url No
Specify the URL of the HTTP server for applet access. Specify the IP address
and port number that match those specified in the codebase attribute.
video_width Yes
This parameter specifies the video image display size (in pixels). Specify the
width. The display sizes are 80 to 640, and any value can be set as the width.
The height is calculated as 3/4 of the specified width. Eg. video_width=“240”
(height=240
× 3/4=180.)
auto_connect Yes
Specifies whether or not connection to the camera server should be established
at the same time that the applet starts up. Select “on” or “off”. When “on” is selected,
connection is established when the applet starts up and moving pictures are
displayed. With “off”, the connection is not established when the applet starts up
and the character string that was specified with the “no_connect_msg” parameter
is displayed. The “connect()” method is called up to establish connections.
bg_image Yes
The picture displayed in the background of LiveApplet can be specified. A JPEG
or GIF file can be specified. The WebView Livescope logo is not displayed if
specified. If not specified, the default picture is used.
click_action Yes
Specifies behavior when a moving picture display area is clicked. “pt” specifies
pan and tilt; “none” specifies no reaction. The default is “pt”.
connect_msg Yes
Specifies the character string that is displayed while connection to the camera
server is being established. The default is “now connecting”.
controller_style Yes
Specifies the GUI style for controlling the camera. “normal” specifies the usual
GUI style; “preset_only” specifies preset operation only; “none” specifies that the
entire GUI will not be displayed. With “preset_only”, only the Control Start button,
the Camera Control Status window, the Preset Selection bar, and the Snapshot
button are displayed.
disconnect_msg Yes
Specifies the character string that is displayed when the connection to the camera
server is cut. The default is “disconnected”.
error_msg Yes
Specifies the character string that is displayed when connection to the camera
server has failed. The default is “can’t connect”.
font_size Yes
Specifies the display size for connect_msg, disconnect_msg, error_msg,
no_connect_msg, and too_many_msg. The default makes size dependent on
the display area.
image_offset Yes
Specifies the display position of the picture file specified at bg_image. With the
upper left coordinates of the picture at “0,0” and the right direction given as x and
the down direction as y, image_offset is specified as “x,y”. The default is “335,0”.
no_connect_msg Yes
Specifies the character string to be displayed following applet startup when
auto_connect is “off”. The default is “no connection”.
overlay_font_color Yes
Specifies the color of the character string specified for “comment” and “hostname”.
The color is specified at “#RRGGBB”. The default is yellow.
show_logo Yes
