| 7 | ============ | ||
| 8 | |||
| 9 | Name | ||
| 10 | ---- | ||
| 11 | swaygrab - Grab image data from the current sway session. | ||
| 12 | |||
| 13 | Synopsis | ||
| 14 | -------- | ||
| 15 | 'swaygrab' [options] [file] | ||
| 16 | |||
| 17 | Grabs pixels from an output and writes them to _file_. The image will be passed to | ||
| 18 | ImageMagick convert for processing. | ||
| 19 | |||
| 20 | Options | ||
| 21 | ------- | ||
| 22 | |||
| 23 | *-h, --help*:: | ||
| 24 | Show help message and quit. | ||
| 25 | |||
| 26 | *-c, \--capture*:: | ||
| 27 | Captures multiple frames as video and passes them into ffmpeg. Continues until | ||
| 28 | you send SIGTERM (ctrl+c) to swaygrab. | ||
| 29 | |||
| 30 | *-o, \--output* <output>:: | ||
| 31 | Use the specified _output_. If no output is defined the currently focused | ||
| 32 | output in sway will be used. | ||
| 33 | |||
| 34 | *-v, \--version*:: | ||
| 35 | Print the version (of swaymsg) and quit. | ||
| 36 | |||
| 37 | *-s, --socket* <path>:: | ||
| 38 | Use the specified socket path. Otherwise, swaymsg will ask sway where the | ||
| 39 | socket is (which is the value of $SWAYSOCK, then of $I3SOCK). | ||
| 40 | |||
| 41 | *-R, --rate* <rate>:: | ||
| 42 | Specify a framerate (in frames per second). Used in combination with -c. | ||
| 43 | Default is 30. Must be an integer. | ||
| 44 | |||
| 45 | *-r, --raw*:: | ||
| 46 | Instead of invoking ImageMagick or ffmpeg, dump raw rgba data to stdout. | ||
| 47 | |||
| 48 | *-f, --focused*:: | ||
| 49 | Capture only the currently focused container. | ||
| 50 | |||
