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
|
|

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.
|
|
|
|

|
|
|
|
-b Do not show info bar on bottom of window
|
|
