NSXIV(1) General Commands Manual NSXIV(1) NAME nsxiv - Neo Simple X Image Viewer SYNOPSIS nsxiv [-abcfhiopqrtvZ0] [-A FRAMERATE] [-e WID] [-G GAMMA] [-g GEOME- TRY] [-N NAME] [-T TITLE] [-n NUM] [-S DELAY] [-s MODE] [-z ZOOM] FILE... DESCRIPTION nsxiv is a simple image viewer for X. It has two modes of operation: image and thumbnail mode. The default is image mode, in which only the current image is shown. In thumbnail mode a grid of small previews is displayed, making it easy to choose an im- age to open. Please note, that the fullscreen mode requires an EWMH/NetWM compliant window manager. OPTIONS -A FRAMERATE Play animations with a constant frame rate set to FRAMERATE. -a Play animations of multi-frame images. -b Do not show info bar on bottom of window. -c Remove all orphaned cache files from the thumbnail cache direc- tory and exit. -e WID Embed nsxiv's window into window whose ID is WID. -f Start in fullscreen mode. -G GAMMA Set image gamma to GAMMA (-32..32). -g GEOMETRY Set window position and size. See section GEOMETRY SPECIFICA- TIONS of X(7) for more information on GEOMETRY argument. -N NAME Set the resource name of nsxiv's X window to NAME. -T TITLE Set the window title to TITLE. Use the format `prefix:suffix- mode'. Any string literal is accepted for prefix, and the format of suffixmode is: Value Format 0 Empty 1 Basename of file 2 Full path to file By defualt, prefix is set to "nsxiv - " and suffixmode is set to 1 (basename). -n NUM Start at picture number NUM. -h Print brief usage information to standard output and exit. -i Read names of files to open from standard input. Also done if FILE is `-'. -o Write list of all marked files to standard output when quitting. In combination with -i nsxiv can be used as a visual fil- ter/pipe. -p Enable private mode, in which nsxiv does not write any cache or temporary files. -q Be quiet, disable warnings to standard error stream. -r Search the given directories recursively for images to view. -S DELAY Start in slideshow mode. Set the delay between images to DELAY seconds. DELAY may be a floating point number. -s MODE Set scale mode according to MODE character. Supported modes are: [d]own, [f]it, [F]ill, [w]idth, [h]eight. -t Start in thumbnail mode. -v Print version information to standard output and exit. -Z The same as `-z 100'. -z ZOOM Set zoom level to ZOOM percent. -0 Use NULL-separator. With this option output of -o and file-list sent to the key-handler and the input of -i will be seperated by a NULL character.

H Scroll to left image edge. J Scroll to bottom image edge. K Scroll to top image edge. L Scroll to right image edge. Zooming: = Set zoom level to 100%, or count%. w Set zoom level to 100%, but fit large images into window. W Fit image to window. F Fill image to window. e Fit image to window width. E Fit image to window height. Rotation: < Rotate image counter-clockwise by 90 degrees. > Rotate image clockwise by 90 degrees. ? Rotate image by 180 degrees. Flipping: | Flip image horizontally. _ Flip image vertically. Miscellaneous: a Toggle anti-aliasing. A Toggle visibility of alpha-channel, i.e. image transparency. s Toggle slideshow mode and/or set the delay between images to count seconds. MOUSE COMMANDS The following mouse mappings are available in image mode: General: Button3 Switch to thumbnail mode. Navigate image list: Button1 Go to the next image if the mouse cursor is in the right part of the window or to the previous image if it is in the left part. Panning: Button2 Pan the image according to the mouse cursor position in the win- dow while keeping this button pressed down. Ctrl-Button1 Pan the image relative to the mouse cursor. Zooming: ScrollUp Zoom in. ScrollDown Zoom out. CONFIGURATION The following X resources are supported: window.background Color of the window background window.foreground Color of the window foreground bar.font Name of Xft bar font bar.background Color of the bar background. Defaults to window.background bar.foreground Color of the bar foreground. Defaults to window.foreground mark.foreground Color of the mark foreground. Defaults to window.foreground Please see xrdb(1) on how to change them. STATUS BAR The information displayed on the left side of the status bar can be re- placed with the output of a user-provided script, which is called by nsxiv whenever an image gets loaded. The path of this script is $XDG_CONFIG_HOME/nsxiv/exec/image-info and the arguments given to it are: 1) path to image file, 2) image width, 3) image height. There is also an example script installed together with nsxiv as /usr/local/share/examples/nsxiv/image-info. EXTERNAL KEY HANDLER Additional external keyboard commands can be defined using a handler program located in $XDG_CONFIG_HOME/nsxiv/exec/key-handler. The han- dler is invoked by pressing Ctrl-x. The next key combo is passed as its first argument. Passed via stdin are the images to act upon: all marked images, if in thumbnail mode and at least one image has been marked, otherwise the current image. nsxiv(1) will block until the han- dler terminates. It then checks which images have been modified and re- loads them. By default nsxiv(1) will send one image per-line to stdin, however when using -0 the image list will be NULL separated and the enviornment variable "$NSXIV_USING_NULL" will be set to 1. The key combo argument has the following form: "[C-][M-][S-]KEY", where C/M/S indicate Ctrl/Meta(Alt)/Shift modifier states and KEY is the X keysym as listed in /usr/include/X11/keysymdef.h without the "XK_" pre- fix. If KEY has an uppercase equivalent, S-KEY is resolved into it. For instance, K replaces S-k and Scedilla replaces S-scedilla, but S- Delete is sent as-is. There is also an example script installed together with nsxiv as /usr/local/share/examples/nsxiv/key-handler. THUMBNAIL CACHING nsxiv stores all thumbnails under $XDG_CACHE_HOME/nsxiv/. Use the command line option -c to remove all orphaned cache files. Ad- ditionally, run the following command afterwards inside the cache di- rectory to remove empty subdirectories: find . -depth -type d -empty ! -name '.' -exec rmdir {} \; ORIGINAL AUTHOR Bert Muennich <ber.t at posteo.de> CURRENT MAINTAINERS Anupam Ashish Minz Berke Kocaolu <berke.kocaoglu at metu.edu.tr> Guilherme Freire Kian Kasad <kian at kasad.com> N-R-K <nrk at disroot.org> Stein Gunnar Bakkeby <bakkeby at gmail.com> TAAPArthur <taaparthur at gmail.com> explosion-mental <explosion0mental at gmail.com> eylles <ed.ylles1997 at gmail.com> qsmodo CONTRIBUTORS Bastien Dejean <nihilhill at gmail.com> Dave Reisner <d at falconindy.com> Fung SzeTat <sthorde at gmail.com> Max Voit <mvdev at with-eyes.net> For additional contributors, run `git shortlog -s` in the nsxiv repository.
