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. that's it, that's the whole vibe. it just takes the picture 💅

This manual page documents version 1.2a of vncsnapshot. yes bestie, version 1.2a, write it down 🎀

---

✨ 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. no cap, it's giving "if the server cooperates" energy 🙈
• -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. main character energy: you just sit there and let them come to you 👑
• -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. literally maximum slay 🌈
• -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. the yapper setting, we love her 🗣️
• -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. 🧠
