++.SH DESCRIPTION
++.B vncviewer
++is an Xt\-based client application for the VNC (Virtual Network
++Computing) system. It can connect to any VNC\-compatible server such
++as \fBXvnc\fR or WinVNC, allowing you to control desktop environment
++of a different machine.
++
++You can use F8 to display a pop\-up utility menu. Press F8 twice to
++pass single F8 to the remote side.
++.SH OPTIONS
++.TP
++\fB\-help\fR
++Prints a short usage notice to stderr.
++.TP
++\fB\-listen\fR
++Make the viewer listen on port 5500+\fIdisplay\fR for reverse
++connections from a server. WinVNC supports reverse connections using
++the "Add New Client" menu option, or the \-connect command line
++option. \fBXvnc\fR requires the use of the helper program
++\fBvncconnect\fR.
++.TP
++\fB\-via\fR \fIgateway\fR
++Automatically create encrypted TCP tunnel to the \fIgateway\fR machine
++before connection, connect to the \fIhost\fR through that tunnel
++(TightVNC\-specific). By default, this option invokes SSH local port
++forwarding, assuming that SSH client binary can be accessed as
++/usr/bin/ssh. Note that when using the \fB\-via\fR option, the host
++machine name should be specified as known to the gateway machine, e.g. 
++"localhost" denotes the \fIgateway\fR, not the machine where vncviewer
++was launched. See the ENVIRONMENT section below for the information on
++configuring the \fB\-via\fR option.
++.TP
++\fB\-shared\fR
++When connecting, specify that a shared connection is requested. In
++TightVNC, this is the default mode, allowing you to share the desktop
++with other clients already using it.
++.TP
++\fB\-noshared\fR
++When connecting, specify that the session may not be shared. This
++would either disconnect other connected clients or refuse your
++connection, depending on the server configuration.
++.TP
++\fB\-viewonly\fR
++Disable transfer of mouse and keyboard events from the client to the
++server.
++.TP
++\fB\-fullscreen\fR
++Start in full\-screen mode. Please be aware that operating in
++full\-screen mode may confuse X window managers. Typically, such
++conflicts cause incorrect handling of input focus or make the viewer
++window disappear mysteriously. See the grabKeyboard setting in the
++RESOURCES section below for a method to solve input focus problem.
++.TP
++\fB\-noraiseonbeep\fR
++By default, the viewer shows and raises its window on remote beep
++(bell) event. This option disables such behaviour
++(TightVNC\-specific).
++.TP
++\fB\-user\fR \fIusername\fR
++User name for Unix login authentication. Default is to use current
++Unix user name. If this option was given, the viewer will prefer Unix
++login authentication over the standard VNC authentication.
++.TP
++\fB\-passwd\fR \fIpasswd\-file\fR
++File from which to get the password (as generated by the
++\fBvncpasswd\fR(1) program). This option affects only the standard VNC
++authentication.
++.TP
++\fB\-encodings\fR \fIencoding\-list\fR
++TightVNC supports several different compression methods to encode
++screen updates; this option specifies a set of them to use in order of
++preference. Encodings are specified separated with spaces, and must
++thus be enclosed in quotes if more than one is specified. Available
++encodings, in default order for a remote connection, are "copyrect
++tight hextile zlib corre rre raw". For a local connection (to the same
++machine), the default order to try is "raw copyrect tight hextile zlib
++corre rre". Raw encoding is always assumed as a last option if no
++other encoding can be used for some reason. For more information on
++encodings, see the section ENCODINGS below.
++.TP
++\fB\-bgr233\fR
++Always use the BGR233 format to encode pixel data. This reduces
++network traffic, but colors may be represented inaccurately. The
++bgr233 format is an 8\-bit "true color" format, with 2 bits blue, 3
++bits green, and 3 bits red.
++.TP
++\fB\-owncmap\fR
++Try to use a PseudoColor visual and a private colormap. This allows
++the VNC server to control the colormap.
++.TP
++\fB\-truecolour\fR, \fB\-truecolor\fR
++Try to use a TrueColor visual.
++.TP
++\fB\-depth\fR \fIdepth\fR
++On an X server which supports multiple TrueColor visuals of different
++depths, attempt to use the specified one (in bits per pixel); if
++successful, this depth will be requested from the VNC server.
++.TP
++\fB\-compresslevel \fIlevel\fR
++Use specified compression \fIlevel\fR (0..9) for "tight" and "zlib"
++encodings (TightVNC\-specific). Level 1 uses minimum of CPU time and
++achieves weak compression ratios, while level 9 offers best
++compression but is slow in terms of CPU time consumption on the server
++side. Use high levels with very slow network connections, and low
++levels when working over high\-speed LANs. It's not recommended to use
++compression level 0, reasonable choices start from the level 1.
++.TP
++\fB\-quality \fIlevel\fR
++Use the specified JPEG quality \fIlevel\fR (0..9) for the "tight"
++encoding (TightVNC\-specific). Quality level 0 denotes bad image
++quality but very impressive compression ratios, while level 9 offers
++very good image quality at lower compression ratios. Note that the
++"tight" encoder uses JPEG to encode only those screen areas that look
++suitable for lossy compression, so quality level 0 does not always
++mean unacceptable image quality.
++.TP
++\fB\-nojpeg\fR
++Disable lossy JPEG compression in Tight encoding (TightVNC\-specific). 
++Disabling JPEG compression is not a good idea in typical cases, as
++that makes the Tight encoder less efficient. You might want to use
++this option if it's absolutely necessary to achieve perfect image
++quality (see also the \fB\-quality\fR option).
++.TP
++\fB\-nocursorshape\fR
++Disable cursor shape updates, protocol extensions used to handle
++remote cursor movements locally on the client side
++(TightVNC\-specific). Using cursor shape updates decreases delays with
++remote cursor movements, and can improve bandwidth usage dramatically. 
++.TP
++\fB\-x11cursor\fR
++Use a real X11 cursor with X-style cursor shape updates, instead of
++drawing the remote cursor on the framebuffer. This option also
++disables the dot cursor, and disables cursor position updates in
++non-fullscreen mode.
++.TP
++\fB\-autopass\fR
++Read a plain-text password from stdin. This option affects only the
++standard VNC authentication.
++
++.SH Enhanced TightVNC Viewer (SSVNC) OPTIONS
++.TP
++Enhanced TightVNC Viewer (SSVNC) web page is located at:
++.TP
++http://www.karlrunge.com/x11vnc/ssvnc.html
++.TP
++Note: ZRLE encoding is now supported.
++.TP
++Note: F9 is shortcut to Toggle FullScreen mode.
++.TP
++\fB\-use64\fR
++In \fB\-bgr233\fR mode, use 64 colors instead of 256.
++.TP
++\fB\-bgr222\fR
++Same as \fB\-use64\fR.
++.TP
++\fB\-use8\fR
++In \fB\-bgr233\fR mode, use 8 colors instead of 256.
++.TP
++\fB\-bgr111\fR
++Same as \fB\-use8\fR.
++.TP
++\fB\-16bpp\fR
++If the vnc viewer X display is depth 24 at 32bpp
++request a 16bpp format from the VNC server to cut
++network traffic by up to 2X, then tranlate the
++pixels to 32bpp locally.
++.TP
++\fB\-bgr565\fR
++Same as \fB\-16bpp\fR.
++.TP
++\fB\-grey\fR
++Use a grey scale for the 16- and 8\fB\-bpp\fR modes.
++.TP
++\fB\-alpha\fR
++Use alphablending transparency for local cursors
++requires: x11vnc server, both client and server
++must be 32bpp and same endianness.
++.TP
++\fB\-ycrop\fR n
++Only show the top n rows of the framebuffer.  For
++use with x11vnc \fB\-ncache\fR client caching option
++to help "hide" the pixel cache region.
++Use a negative value (e.g. \fB\-1\fR) for autodetection.
++Autodetection will always take place if the remote
++fb height is more than 2 times the width.
++.TP
++\fB\-sbwidth\fR n
++Scrollbar width for x11vnc \fB\-ncache\fR mode (\fB\-ycrop\fR),
++default is very narrow: 2 pixels, it is narrow to
++avoid distraction in \fB\-ycrop\fR mode.
++.TP
++\fB\-nobell\fR
++Disable bell.
++.TP
++\fB\-rawlocal\fR
++Prefer raw encoding for localhost, default is
++no, i.e. assumes you have a SSH tunnel instead.
++.TP
++\fB\-graball\fR
++Grab the entire X server when in fullscreen mode,
++needed by some old window managers like fvwm2.
++.TP
++\fB\-popupfix\fR
++Warp the popup back to the pointer position,
++needed by some old window managers like fvwm2.
++.TP
++\fB\-grabkbd\fR
++Grab the X keyboard when in fullscreen mode,
++needed by some window managers. Same as \fB\-grabkeyboard\fR.
++\fB\-grabkbd\fR is the default, use \fB\-nograbkbd\fR to disable.
++.TP
++\fB\-bs\fR, \fB\-nobs\fR
++Whether or not to use X server Backingstore for the
++main viewer window.  The default is to not, mainly
++because most Linux, etc, systems X servers disable
++*all* Backingstore by default.  To re\fB\-enable\fR it put
++Option "Backingstore"
++in the Device section of /etc/X11/xorg.conf.
++In \fB\-bs\fR mode with no X server backingstore, whenever an
++area of the screen is re\fB\-exposed\fR it must go out to the
++VNC server to retrieve the pixels. This is too slow.
++In \fB\-nobs\fR mode, memory is allocated by the viewer to
++provide its own backing of the main viewer window. This
++actually makes some activities faster (changes in large
++regions) but can appear to "flash" too much.
++.TP
++\fB\-noshm\fR
++Disable use of MIT shared memory extension (not recommended)
++.TP
++\fB\-termchat\fR
++Do the UltraVNC chat in the terminal vncviewer is in
++instead of in an independent window.
++.TP
++\fB\-unixpw str\fR
++Useful for logging into x11vnc in -unixpw mode. "str" is a
++string that allows many ways to enter the Unix Username
++and Unix Password.  These characters: username, newline,
++password, newline are sent to the VNC server after any VNC
++authentication has taken place.  Under x11vnc they are
++used for the -unixpw login.  Other VNC servers could do
++something similar.
++You can also indicate "str" via the environment
++variable SSVNC_UNIXPW.
++Note that the Escape key is actually sent first to tell
++x11vnc to not echo the Unix Username back to the VNC
++viewer. Set SSVNC_UNIXPW_NOESC=1 to override this.
++If str is ".", then you are prompted at the command line
++for the username and password in the normal way.  If str is
++"-" the stdin is read via getpass(3) for username@password.
++Otherwise if str is a file, it is opened and the first line
++read is taken as the Unix username and the 2nd as the
++password. If str prefixed by "rm:" the file is removed
++after reading. Otherwise, if str has a "@" character,
++it is taken as username@password. Otherwise, the program
++exits with an error. Got all that?

++
++.SH ENCODINGS
++The server supplies information in whatever format is desired by the
++client, in order to make the client as easy as possible to implement. 
++If the client represents itself as able to use multiple formats, the
++server will choose one.
++
++.I Pixel format
++refers to the representation of an individual pixel. The most common
++formats are 24 and 16 bit "true\-color" values, and 8\-bit "color map"
++representations, where an arbitrary map converts the color number to
++RGB values.
++
++.I Encoding
++refers to how a rectangle of pixels are sent (all pixel information in
++VNC is sent as rectangles). All rectangles come with a header giving
++the location and size of the rectangle and an encoding type used by
++the data which follows. These types are listed below.
++.TP
++.B Raw
++The raw encoding simply sends width*height pixel values. All clients
++are required to support this encoding type. Raw is also the fastest
++when the server and viewer are on the same machine, as the connection
++speed is essentially infinite and raw encoding minimizes processing
++time.
++.TP
++.B CopyRect
++The Copy Rectangle encoding is efficient when something is being
++moved; the only data sent is the location of a rectangle from which
++data should be copied to the current location. Copyrect could also be
++used to efficiently transmit a repeated pattern.
++.TP
++.B RRE
++The Rise\-and\-Run\-length\-Encoding is basically a 2D version of
++run\-length encoding (RLE). In this encoding, a sequence of identical
++pixels are compressed to a single value and repeat count. In VNC, this
++is implemented with a background color, and then specifications of an
++arbitrary number of subrectangles and color for each. This is an
++efficient encoding for large blocks of constant color.
++.TP
++.B CoRRE
++This is a minor variation on RRE, using a maximum of 255x255 pixel
++rectangles. This allows for single\-byte values to be used, reducing
++packet size. This is in general more efficient, because the savings
++from sending 1\-byte values generally outweighs the losses from the
++(relatively rare) cases where very large regions are painted the same
++color.
++.TP
++.B Hextile
++Here, rectangles are split up in to 16x16 tiles, which are sent in a
++predetermined order. The data within the tiles is sent either raw or
++as a variant on RRE. Hextile encoding is usually the best choice for
++using in high\-speed network environments (e.g. Ethernet local\-area
++networks).
++.TP
++.B Zlib
++Zlib is a very simple encoding that uses zlib library to compress raw
++pixel data. This encoding achieves good compression, but consumes a
++lot of CPU time. Support for this encoding is provided for
++compatibility with VNC servers that might not understand Tight
++encoding which is more efficient than Zlib in nearly all real\-life
++situations.
++.TP
++.B Tight
++Like Zlib encoding, Tight encoding uses zlib library to compress the
++pixel data, but it pre\-processes data to maximize compression ratios,
++and to minimize CPU usage on compression. Also, JPEG compression may
++be used to encode color\-rich screen areas (see the description of
++\-quality and \-nojpeg options above). Tight encoding is usually the
++best choice for low\-bandwidth network environments (e.g. slow modem
++connections).
++.SH RESOURCES
++X resources that \fBvncviewer\fR knows about, aside from the
++normal Xt resources, are as follows:
++.TP
++.B shareDesktop
++Equivalent of \fB\-shared\fR/\fB\-noshared\fR options. Default true.
++.TP
++.B viewOnly
++Equivalent of \fB\-viewonly\fR option. Default false.
++.TP
++.B fullScreen
++Equivalent of \fB\-fullscreen\fR option. Default false.
++.TP
++.B grabKeyboard
++Grab keyboard in full-screen mode. This can help to solve problems
++with losing keyboard focus. Default false.
++.TP
++.B raiseOnBeep
++Equivalent of \fB\-noraiseonbeep\fR option, when set to false. Default
++true.
++.TP
++.B passwordFile
++Equivalent of \fB\-passwd\fR option.
++.TP
++.B userLogin
++Equivalent of \fB\-user\fR option.
++.TP
++.B passwordDialog
++Whether to use a dialog box to get the password (true) or get it from
++the tty (false). Irrelevant if \fBpasswordFile\fR is set. Default
++false.
++.TP
++.B encodings
++Equivalent of \fB\-encodings\fR option.
++.TP
++.B compressLevel
++Equivalent of \fB\-compresslevel\fR option (TightVNC\-specific).
++.TP
++.B qualityLevel
++Equivalent of \fB\-quality\fR option (TightVNC\-specific).
++.TP
++.B enableJPEG
++Equivalent of \fB\-nojpeg\fR option, when set to false. Default true.
++.TP
++.B useRemoteCursor
++Equivalent of \fB\-nocursorshape\fR option, when set to false
++(TightVNC\-specific). Default true.
++.TP
++.B useBGR233
++Equivalent of \fB\-bgr233\fR option. Default false.
++.TP
++.B nColours
++When using BGR233, try to allocate this many "exact" colors from the
++BGR233 color cube. When using a shared colormap, setting this resource
++lower leaves more colors for other X clients. Irrelevant when using
++truecolor. Default is 256 (i.e. all of them).
++.TP
++.B useSharedColours
++If the number of "exact" BGR233 colors successfully allocated is less
++than 256 then the rest are filled in using the "nearest" colors
++available. This resource says whether to only use the "exact" BGR233
++colors for this purpose, or whether to use other clients' "shared"
++colors as well. Default true (i.e. use other clients' colors).
++.TP
++.B forceOwnCmap
++Equivalent of \fB\-owncmap\fR option. Default false.
++.TP
++.B forceTrueColour
++Equivalent of \fB\-truecolour\fR option. Default false.
++.TP
++.B requestedDepth
++Equivalent of \fB\-depth\fR option.
++.TP
++.B useSharedMemory
++Use MIT shared memory extension if on the same machine as the X
++server. Default true.
++.TP
++.B wmDecorationWidth, wmDecorationHeight
++The total width and height taken up by window manager decorations.
++This is used to calculate the maximum size of the VNC viewer window. 
++Default is width 4, height 24.
++.TP
++.B bumpScrollTime, bumpScrollPixels
++When in full screen mode and the VNC desktop is bigger than the X
++display, scrolling happens whenever the mouse hits the edge of the
++screen. The maximum speed of scrolling is bumpScrollPixels pixels
++every bumpScrollTime milliseconds. The actual speed of scrolling will
++be slower than this, of course, depending on how fast your machine is. 
++Default 20 pixels every 25 milliseconds.
++.TP
++.B popupButtonCount
++The number of buttons in the popup window. See the README file for
++more information on how to customize the buttons.
++.TP
++.B debug
++For debugging. Default false.
++.TP
++.B rawDelay, copyRectDelay
++For debugging, see the README file for details. Default 0 (off).
++.SH ENVIRONMENT
++When started with the \fB\-via\fR option, vncviewer reads the
++\fBVNC_VIA_CMD\fR environment variable, expands patterns beginning
++with the "%" character, and executes result as a command assuming that
++it would create TCP tunnel that should be used for VNC connection. If
++not set, this environment variable defaults to "/usr/bin/ssh -f -L
++%L:%H:%R %G sleep 20".
++
++The following patterns are recognized in the \fBVNC_VIA_CMD\fR (note
++that all the patterns %G, %H, %L and %R must be present in the command
++template):
++.TP
++.B %%
++A literal "%";
++.TP
++.B %G
++gateway host name;
++.TP
++.B %H
++remote VNC host name, as known to the gateway;
++.TP
++.B %L
++local TCP port number;
++.TP
++.B %R
++remote TCP port number.
