sxiv: Simple (or small or suckless) X Image Viewer
|
|
|
|
sxiv is an alternative to feh and qiv. Its only dependency besides xlib is
|
|
imlib2. 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.
|
|
|
|
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 it into a directory of your choice by changing the second
|
|
command to:
|
|
|
|
# make PREFIX="/your/dir" install
|
|
|
|
All build-time specific settings can be found in the file "config.h". Please
|
|
check and change them, so that they fit your needs.
|
|
|
|
Additional features
|
|
-------------------
|
|
|
|
The XFLAGS and XLIBS macros/environment variables control which additional
|
|
features (i.e. non-default compile-time features) should be enabled and
|
|
included during compilation.
|
|
|
|
The following table lists the available additional features--the column
|
|
*Requires* indicates, which libraries need to be installed for a feature; the
|
|
columns *XFLAGS* and *XLIBS* show, what needs to be added to these
|
|
macros/environment variables to enable the corresponding feature:
|
|
|
|
Feature | Requires | XFLAGS | XLIBS
|
|
----------------------------------+----------+----------------+--------
|
|
GIF support: Load all frames and | giflib | -DGIF_SUPPORT | -lgif
|
|
play animations of GIF files | | |
|
|
----------------------------------+----------+----------------+--------
|
|
EXIF support: auto-orientate JPEG | libexif | -DEXIF_SUPPORT | -lexif
|
|
files according to their EXIF tag | | |
|
|
|
|
For instance, to enable GIF and EXIF support, the giflib and libexif libraries
|
|
need to be installed on your system and you either need to change the first
|
|
build command to:
|
|
|
|
$ make XFLAGS="-DGIF_SUPPORT -DEXIF_SUPPORT" XLIBS="-lgif -lexif"
|
|
|
|
Or you need to run the following commands before building sxiv:
|
|
|
|
$ export XFLAGS="-DGIF_SUPPORT -DEXIF_SUPPORT"
|
|
$ export XLIBS="-lgif -lexif"
|
|
|
|
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 key mappings are available; differences between image view and
|
|
thumbnail mode are denoted via brackets:
