NAME

       imv - Image viewer for X11 and Wayland

DESCRIPTION

       imv is an image viewer for X11 and Wayland, aimed at users of tiling window managers. It
       supports a wide variety of image file formats, including animated gif files. imv will
       automatically reload the current image, if it is changed on disk.

SYNOPSIS

       imv [options] [paths...]

OPTIONS

       -h
           Show help message and quit.

       -v
           Show version and quit.

       -b <background>
           Set the background colour. Can either be a 6-digit hexadecimal colour code or checks
           to show a chequered background.

       -c <command>
           Specify a command to be run on launch, after the configuration has been loaded. Can be
           used to configure custom keys with the bind command. This option can be used multiple
           times. Commands are run in the order that they have been passed to imv.

       -d
           Start with overlay visible.

       -f
           Start fullscreen.

       -l
           List open files to stdout at exit.

       -n <path|index>
           Start with the given path, or index selected.

       -r
           Load directories recursively.

       -s <none|shrink|full|crop>
           Set scaling mode to use.  none will show each image at its actual size.  shrink will
           scale down the image to fit inside the window.  full will both scale up and scale down
           the image to fit perfectly inside the window.  crop will scale and crop the image to
           fill the window. Defaults to full.

       -t <slideshow_duration>
           Start in slideshow mode, with each image shown for the given number of seconds.

       -u <linear|nearest_neighbour>
           Set upscaling method used by imv.

       -x
           Disable looping of input paths.

COMMANDS

       Commands can be entered by pressing :. imv supports the following commands:

CONFIGURATION

       The path to a config file can be given via the $imv_config environment variable. If not
       found, imv will search for it in the following locations:

       •   $XDG_CONFIG_HOME/imv/config (recommended)

       •   $HOME/.config/imv/config

       •   $HOME/.imv_config

       •   $HOME/.imv/config

       •   /usr/local/etc/imv_config

       •   /etc/imv_config

       A default config file is shipped with imv into /etc/imv_config

       For documentation on the config file format, see imv(5).

ENVIRONMENT VARIABLES

       When imv executes a shell command, it provides a number of environment variables, exposing
       imv’s state. These environment variables are also available when customising the window’s
       title, or the overlay text.

       $imv_pid
           The pid of this instance of imv. Useful for running imv-msg in scripts.

       $imv_current_file
           Path of currently selected image.

       $imv_scaling_mode
           Name of the current scaling mode.

       $imv_loading
           1 if a new image is loading, 0 otherwise.

       $imv_current_index
           Index of current image, from 1-N.

       $imv_file_count
           Total number of files.

       $imv_width
           Width of the current image.

       $imv_height
           Height of the current image.

       $imv_scale
           Scaling of current image in percent.

       $imv_slideshow_duration
           Number of seconds each image is shown for.

       $imv_slideshow_elapsed
           How long the current image has been shown for.

IPC

       imv can accept commands from another process over a unix socket. Each instance of imv will
       open a unix socket named $XDG_RUNTIME_DIR/imv-$PID.sock. If $XDG_RUNTIME_DIR is undefined,
       the socket is placed into /tmp/ instead.

       The imv-msg(1) utility is provided to simpliy this from shell scripts.
