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 image to open. +.P +Please note, that the fullscreen mode requires an EWMH/NetWM compliant window +manager. +.SH OPTIONS +.TP +.BI "\-A " FRAMERATE +Play animations with a constant frame rate set to +.IR FRAMERATE . +.TP +.B \-a +Play animations of multi-frame images. +.TP +.B \-b +Do not show info bar on bottom of window. +.TP +.B \-c +Remove all orphaned cache files from the thumbnail cache directory and exit. +.TP +.BI "\-e " WID +Embed nsxiv's window into window whose ID is +.IR WID . +.TP +.B \-f +Start in fullscreen mode. +.TP +.BI "\-G " GAMMA +Set image gamma to GAMMA (\-32..32). +.TP +.BI "\-g " GEOMETRY +Set window position and size.

The path of this script is +.I $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. +.P +There is also an example script installed together with nsxiv as +.IR PREFIX/share/nsxiv/exec/image-info . +.SH EXTERNAL KEY HANDLER +Additional external keyboard commands can be defined using a handler program +located in +.IR $XDG_CONFIG_HOME/nsxiv/exec/key-handler . +The handler is invoked by pressing +.BR Ctrl-x . +The next key combo is passed as its first argument. Passed via stdin are the +images to act upon, one path per line: 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 handler terminates. It then checks which images +have been modified and reloads them. + +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_" prefix. + +There is also an example script installed together with nsxiv as +.IR PREFIX/share/nsxiv/exec/key-handler . +.SH THUMBNAIL CACHING +nsxiv stores all thumbnails under +.IR $XDG_CACHE_HOME/nsxiv/ . +.P +Use the command line option +.I \-c +to remove all orphaned cache files. Additionally, run the following command +afterwards inside the cache directory to remove empty subdirectories: +.P +.RS +find . \-depth \-type d \-empty ! \-name '.' \-exec rmdir {} \\; +.RE +.SH ORIGINAL AUTHOR +.EX +Bert Muennich <ber.t at posteo.de> +.EE +.SH CURRENT MAINTAINERS +.EX +Anupam Ashish Minz +Berke Kocaoğlu <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 +.EE +.SH CONTRIBUTORS +.EX +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. +.EE +.SH HOMEPAGE +.EX +https://github.com/nsxiv/nsxiv +.EE +.SH SEE ALSO +.BR X (7), +.BR xrdb (1) |
