sxiv
====
**Simple 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 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
-----
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.
**Command line options:**
-b Do not show info bar on bottom of window
-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))
-i Read file list from stdin
-n NUM Start at picture NUM
-N NAME Set X window resource name to NAME
-o Write file list to stdout when quitting
-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
**Key mappings:**
q Quit sxiv
Return Switch to thumbnail mode / open selected image
0-9 Prefix the next command with a number (denoted via [count])
g Go to first image
G Go to the last image, or image number [count]
f Toggle fullscreen mode (requires an EWMH/NetWM compliant
window manager)
b Toggle visibility of info bar on bottom of window
A Toggle visibility of alpha-channel, i.e. transparency
r Reload image
R Reload all thumbnails
D Remove image from file list and go to next image
*Thumbnail mode:*
h,j,k,l Move selection left/down/up/right [count] times
Ctrl-j,k Scroll thumbnail grid one window height down/up
*Image mode:*
n,Space Go [count] images forward
p,Backspace Go [count] images backward
[,] Go [count] * 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
= Set zoom level to 100%, or [count]%
w Fit image into window
e Fit image width to window width
E Fit image height to window height
h,j,k,l Pan image 1/5 of window width/height or [count] pixels
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
\,| Flip image horizontally/vertically
a Toggle anti-aliasing
W Resize window to fit image
**Mouse button mappings:**
*Image mode:*
Button1 Go to the next image
Button2 Drag image with mouse while keeping it pressed
Button3 Go to the previous image
Scroll Pan image up/down
Shift+Scroll Pan image left/right
Ctrl+Scroll Zoom in/out
