3**Simple X Image Viewer**
4
5sxiv is an alternative to feh and qiv. Its only dependencies besides xlib are
6imlib2 and giflib. The primary goal for writing sxiv is to create an image
7viewer, which only has the most basic features required for fast image viewing
8(the ones I want). It has vi key bindings and works nicely with tiling window
9managers. Its code base should be kept small and clean to make it easy for you
10to dig into it and customize it for your needs.
11
12
13Features
14--------
15
16* Basic image operations, e.g. zooming, panning, rotating
17* Customizable key and mouse button mappings (in *config.h*)
18* Thumbnail mode: grid of selectable previews of all images
19* Ability to cache thumbnails for fast re-loading
20* Basic support for multi-frame images
21* Load all frames from GIF files and play GIF animations
22* Display image information in status bar

37Installation
38------------
39
40sxiv is built using the commands:
41
42 $ make
43 # make install
44
45Please note, that the latter one requires root privileges.
46By default, sxiv is installed using the prefix "/usr/local", so the full path
47of the executable will be "/usr/local/bin/sxiv".
48
49You can install sxiv into a directory of your choice by changing the second
50command to:
51
52 # make PREFIX="/your/dir" install
53
54The build-time specific settings of sxiv can be found in the file *config.h*.
55Please check and change them, so that they fit your needs.
56If the file *config.h* does not already exist, then you have to create it with
57the following command:
58
59 $ make config.h
60
61
62Usage
63-----
64
65sxiv has two modes of operation: image and thumbnail mode. The default is
66image mode, in which only the current image is shown. In thumbnail mode a grid
67of small previews is displayed, making it easy to choose an image to open.

69**Command line options:**
70
71 -b Do not show info bar on bottom of window
72 -c Remove all orphaned cache files from thumbnail cache and exit
73 -d Scale all images to 100%, but fit large images into window
74 -F Use size-hints to make the window fixed/floating
75 -f Start in fullscreen mode
76 -G GAMMA Set image gamma to GAMMA (-32..32)
77 -g GEOMETRY Set window position and size
78 (see section GEOMETRY SPECIFICATIONS of X(7))
79 -i Read file list from stdin
80 -N NAME Set X window resource name to NAME
81 -n NUM Start at picture NUM
82 -o Write list of marked files to stdout when quitting
83 -q Be quiet, disable warnings
84 -r Search given directories recursively for images
85 -S DELAY Enable slideshow and set slideshow delay to DELAY seconds
86 -s Scale all images to fit into window
87 -t Start in thumbnail mode
88 -v Print version information and exit
