sxiv: Simple (or small or suckless) X Image Viewer

sxiv is a really simple alternative to feh and qiv. Its only dependency besides xlib is imlib2. The primary goal for writing sxiv is to create an image viewer, which only implements the most basic features required for fast image viewing. It works nicely with tiling window managers and its code base should be kept small and clean to make it easy for you to dig into it and customize it for your needs.

Installation

sxiv is built using the commands:

$ make
# make install

Please note, that the latter one requires root privileges. By default, sxiv is installed using the prefix "/usr/local", so the full path of the executable will be "/usr/local/bin/sxiv".

You can install it into a directory of your choice by changing the second command to:

# PREFIX="/your/dir" make install

All build-time specific settings can be found in the file "config.h". Please check and change them, so that they fit your needs.

Usage

sxiv 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 image to open.

sxiv supports the following command-line options:

-d           Scale all images to 100%, but fit large images into window
-F           Use size-hints to make the window fixed/floating
-f           Start in fullscreen mode
-g GEOMETRY  Set window position and size
             (see section GEOMETRY SPECIFICATIONS of X(7))
-p           Pixelize, i.e. turn off image anti-aliasing
-q           Be quiet, disable warnings
-r           Search given directories recursively for images
-s           Scale all images to fit into window
-t           Start in thumbnail mode
-v           Print version information and exit
-Z           Same as `-z 100'
-z ZOOM      Scale all images to current zoom level, use ZOOM at startup

Use the following keys to control the basic behaviour of sxiv:

q            Quit sxiv
Escape       Quit sxiv and return an exit value of 2 (useful for scripting)
f            Toggle fullscreen mode (requires an EWMH/NetWM compliant
             window manager)

Inside image view mode, the following key mappings are available:

n,Space      Go to the next image
p,Backspace  Go to the previous image
g/G          Go to first/last image
[/]          Go 10 images backward/forward
+,=          Zoom in
-            Zoom out
0            Set zoom level to 100%
w            Fit image into window
h,j,k,l      Pan image left/down/up/right (also with arrow keys)
<,>          Rotate image (counter-)clockwise by 90 degrees
W            Resize window to fit image
a            Toggle anti-aliasing
A            Toggle visibility of alpha-channel, i.e. transparency
r            Reload image
Return       Switch to thumbnail mode

Additionally, the image view offers the following mouse commands:

Button1           Go to the next image
Button2           Drag image with mouse while keeping it pressed
Button3           Go to the previous image
ScrollUp          Pan image up
ScrollDown        Pan image down
Shift+ScrollUp    Pan image left
Shift+ScrollDown  Pan image right
Ctrl+ScrollUp     Zoom in
Ctrl+ScrollDown   Zoom out

In thumbnail mode, the following key and mouse mappings are available:

h,j,k,l      Move selection left/down/up/right (also with arrow keys)
g/G          Move selection to first/last image
Return       Open selected image

Button1      Select image/open image if it is already selected
ScrollUp     Scroll up one row
ScrollDown   Scroll down one row
