sxiv: Simple (or small or suckless) X Image Viewer
sxiv is an 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 has the most basic features required for fast image viewing (the ones I
want). It has vi key bindings and works nicely with tiling window managers.
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.
Features
--------
* Basic image operations, e.g. zooming, panning, rotating
* Customizable key and mouse button mappings (in *config.h*)
* Thumbnail mode: grid of selectable previews of all images
* Ability to cache thumbnails for fast re-loading
* Basic support for multi-frame images
* Display image information in window title
Additional features, that need to be enabled at compile-time (in *config.h*),
because they depend on additional libraries:
* Load all frames from GIF files and play GIF animations (requires giflib)
* Auto-orientate JPEG images according to their EXIF tags (requires libexif)

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 sxiv into a directory of your choice by changing the second
command to:
# make PREFIX="/your/dir" install
The build-time specific settings of sxiv can be found in the file *config.h*.
Please check and change them, so that they fit your needs.
If the file *config.h* does not already exist, then you have to create it with
the following command:
$ make config.h
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:
-c Remove all orphaned cache files from thumbnail cache and exit
-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))
-n NUM Start at picture NUM
-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
The following key mappings are available; differences between image view and
thumbnail mode are denoted via brackets:
q Quit sxiv
Return Switch to thumbnail mode [open selected image]
n,Space Go to the next image
p,Backspace Go to the previous image
g,G Go to [select] first/last image
[,] Go 10 images backward/forward
Ctrl-n,p Go to the next/previous frame of a multi-frame image
Ctrl-Space Play/pause animation of a multi-frame image
+,= Zoom in
- Zoom out
0 Set zoom level to 100%
w Fit image into window
h,j,k,l Pan image [move selection] left/down/up/right
(also with arrow keys)
H,J,K,L Pan to left/bottom/top/right image edge
Ctrl-h,j,k,l Pan image one window width/height left/down/up/right
(also with Ctrl-arrow keys)
<,> Rotate image (counter-)clockwise by 90 degrees
W Resize window to fit image
f Toggle fullscreen mode (requires an EWMH/NetWM compliant
window manager)
a Toggle anti-aliasing
A Toggle visibility of alpha-channel, i.e. transparency
D Remove image from file list and go to [select] next image
r Reload image
Additionally, the following mouse mappings are available:
Button1 Go to the next image
[select image/open image if it is already selected]
Button2 Drag image with mouse while keeping it pressed
Button3 Go to the previous image
Scroll Pan image up/down [scroll up/down one thumbnail row]
Shift+Scroll Pan image left/right
Ctrl+Scroll Zoom in/out
