swaygrab (1)
============

Name
----
swaygrab - Grab image data from the current sway session.

Synopsis
--------
'swaygrab' [options] [file]

Grabs pixels from an output and writes them to _file_. The image will be passed to
ImageMagick convert for processing.

Options
-------

*-h, --help*::
	Show help message and quit.

*-c, \--capture*::
	Captures multiple frames as video and passes them into ffmpeg. Continues until
	you send SIGTERM (ctrl+c) to swaygrab.

*-o, \--output* <output>::
	Use the specified _output_. If no output is defined the currently focused
	output in sway will be used.

*-v, \--version*::
	Print the version (of swaymsg) and quit.

*-s, --socket* <path>::
	Use the specified socket path. Otherwise, swaymsg will ask sway where the
	socket is (which is the value of $SWAYSOCK, then of $I3SOCK).

*-R, --rate* <rate>::
	Specify a framerate (in frames per second). Used in combination with -c.
	Default is 30. Must be an integer.

*--raw*::
	Instead of invoking ImageMagick or ffmpeg, dump raw rgba data to stdout.

Examples
--------

swaygrab output.png::
	Grab the contents of currently focused output and write to output.png.

swaygrab -c -o HDMI-A-1 output.webm::
	Capture a webm of HDMI-A-1.
