vncsnapshot(1) VNC vncsnapshot(1)
NAME
vncsnapshot - grab snapshots from VNC servers
SYNTAX
vncsnapshot [options] host:display JPEG-file
vncsnapshot [options] -listen local-display JPEG-file
vncsnapshot [options] -tunnel host:display JPEG-file
vncsnapshot [options] -via gateway host:display JPEG-file
DESCRIPTION
VNC Snapshot is a command-line program for VNC. It will save a JPEG image of the VNC server's screen.
This manual page documents version 1.2a of vncsnapshot.
OPTIONS
-allowblank
Allow blank (all black) images as snapshots. See -ignoreblank. -compresslevel level Compress network messages to level, if the
server supports it. level is between 0 and 9, with 0 being no compression and 9 the maximum. The default is 4.
-cursor
Include the cursor in snapshots. Only effective if the remote server is a TightVNC version; otherwise ignored.
-encodings list
Use the given encodings. The default is
"copyrect tight hextile zlib corre rre"
or
"raw copyrect tight hextile zlib corre rre"
when VNC snapshot and the server are on the same machine.
-ignoreblank
Ignore blank (all black) screens; do not save the screen until a screen that is not all black is received. This is useful with some
servers that send an initial all-black screen before sending the actual screen. This is the default.
-jpeg Request the remote server to use JPEG-style encoding when sending the image, if possible. Currently only supported by TightVNC (and
servers derived from it). This is the default.
-nocursor
Do not include the cursor in snapshots. Only effective if the remote server is a TightVNC version; otherwise ignored. This is the
default.
-nojpeg
Request the remote server to not use JPEG-style encoding when sending the image, if possible. Currently only supported by TightVNC
(and servers derived from it).
-listen local-display
Do not connect to a server; wait for the server to connect to the specified local "display". Cannot be used with -tunnel or -via
options.
-passwd filename
Read encrypted password from filename instead of from the console. The filename can be made with the vncpasswd utility included with
the vncsnapshot release.
-quality quality
Use the specified JPEG image quality (0-100) for the output file. The default is 100.
-quiet Do not print any messages. Opposite of -verbose.
-rect wxh+x+y
Save a sub-rectangle of the screen, width w height h offset from the left by x and the top by y.
A negative number for x or y makes it an offset from the opposite edge.
A zero value for the width or height makes the snapshot extend to the right or bottom of the screen, respectively.
The default is the entire screen.
-tunnel
Connect to the remote server via an SSH tunnel. Cannot be used with -listen or -via options.
-via gateway
Connect to the remote server via an SSH tunnel on the host gateway. Cannot be used with -listen or -tunnel options.
-verbose
Print messages; default.
-vncQuality quality
Use the specified image quality level (0-9) for tight encoding. The default is 9. Only effective if the remote server is a TightVNC
version; otherwise ignored.
-count number
Take number snapshots; default 1. If greater than 1, vncsnapshot will insert a five-digit sequence number just before the output
file's extension; i.e. if you specify out.jpeg as the output file, it will create out00001.jpeg, out00002.jpeg, and so forth
-fps rate
When taking multiple snapshots, take them every rate seconds; default 60.
EXAMPLES
vncsnapshot anhk-morpork:1 unseen.jpg
Get a snapshot of screen 1 from the server ahnk-morpork and save it in unseen.jpg. The entire screen is saved; the default transport
is used.
vncsnapshot -listen 0 portrait.jpeg
Wait for a server to connect to this host (using "screen" 0), and then save the full screen image in portrait.jpeg.
vncsnapshot -passwd ~/.vnc/passwd -rect 640x0+120+30 :1 subarea.jpeg
Using ~/.vnc/passwd to get the server's password, connect to screen 1 on the local machine and save a rectangle 640 pixels high and
extending to the right edge, offset 120 pixels from the left and 30 pixels down.
vncsnapshot -rect 0x0-800-600 :1 pict.jpeg
Get a snapshot that is 800 pixels from the right edge and 600 pixels from the bottom of the screen. It will extend to the screen
edges, making it 800x600. Alternatively, the rectangle could be given as -rect 800x600-0-0, which specifies the same region.
