**Simple X Image Viewer**

sxiv is an alternative to feh and qiv. Its only dependencies besides xlib are
imlib2, libexif 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 status bar

**Thumbnail mode:**

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
-----

Please see the [man page](http://muennich.github.com/sxiv/sxiv.1.html) for information on how to use sxiv.
