# xwallpaper

The xwallpaper utility allows you to set image files as your X wallpaper.
JPEG, PNG, and XPM file formats are supported, all of them being configurable
and therefore no fixed dependencies.

The wallpaper is also advertised to programs which support semi-transparent
backgrounds.

## Motivation

The aim of this project is to create a minimalistic wallpaper utility which
focuses on the most common use cases.

It directly depends on libraries which are used by X, like libxcb, and
therefore has no further hard dependencies on projects which are not already
on your system due to having a basic X environment.

The last but not least focus of this project is to write a secure wallpaper
utility, supporting very tight sandboxing mechanisms. A careful approach right
from the start made this especially easy.

## Installation

The build environment is based on autotools just like other X components.
Building and installing is as simple as:

    ./autogen.sh
    ./configure
    make
    make install

To support all file formats, your system needs libjpeg-turbo, libpng, and
libXpm. If one of the libraries is not found, the specific file format will
not be supported. Also, if you compile for OpenBSD, the system call pledge
is automatically used. On Linux systems, libseccomp is used if available to
filter system calls.
