sxiv: Simple (or small or suckless) X Image Viewer
sxiv is an alternative to feh and qiv. Its only dependencies besides xlib are
imlib2 and giflib. 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
* Load all frames from GIF files and play GIF animations
* Display image information in window title

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 general key commands are available:
q Quit sxiv
Return Switch to thumbnail mode / open selected image
0-9 Prefix the next command with a number (denoted via [count])
