Wallpaper (computing)

The X Window System was one of the earliest systems to include support for an arbitrary image as wallpaper via the xsetroot program, which at least as early as the X10R3 release in 1985 could tile the screen with any solid color or any binary-image X BitMap file. In 1989, a free software program called was released that allowed an arbitrary color GIF image to be used as wallpaper, and in the same year the free xloadimage program was released which could display a variety of image formats (including color images in Sun Rasterfile format) as the desktop background. Subsequently, a number of programs were released that added wallpaper support for additional image formats and other features, such as the xpmroot program (released in 1993 as part of fvwm) and the xv software (released in 1994). The original Macintosh operating system only allowed a selection of 8×8-pixel binary-image tiled patterns; the ability to use small color patterns was added in System 5 in 1987. Mac OS 8 in 1997 was the first Macintosh version to include built-in support for using arbitrary images as desktop pictures, rather than small repeating patterns. Windows 3.0 in 1990 was the first version of Microsoft Windows to feature support for wallpaper customization, and used the term "wallpaper" for this feature. Although Windows 3.0 only came with 7 small patterns (2 black-and-white and 5 16-color), the user could supply other images in the BMP file format with up to 8-bit color (although the system was theoretically capable of handling 24-bit color images, it did so by dithering them to an 8-bit palette) to provide similar wallpaper features otherwise lacking in those systems. A wallpaper feature was added in a beta release of OS/2 2.0 in 1991. Due to the widespread use of personal computers, some wallpapers have become immensely recognizable and gained iconic cultural status. Bliss, the default wallpaper of Windows XP, has become the most viewed photograph of the 2000s. ==Animated backgrounds==

on Windows 11 Animated backgrounds (sometimes referred to as live backgrounds or dynamic backgrounds) refers to wallpapers which feature a moving image or a 2D / 3D scene as an operating system background rather than a static image, it may also refer to wallpapers being cycled in a playlist, often with certain transition effects. Some operating systems, such as Android, provide native support for animated wallpapers. Microsoft Windows Windows has had several ways of implementing dynamic backgrounds over the years. For example: • Active Desktop, which is included in Windows 95 OSR 2.5 through Windows XP, allows web apps to run as desktop background and deliver live contents. Animation is one of the possibilities. • Windows DreamScene, only included with the Ultimate edition of Windows Vista, allows videos of any supported format (including animated GIFs) as wallpapers. • Starting with Windows 7, the OS can cycle through pictures from a folder at regular intervals. While this does not support animated backgrounds, it does enable third-party software (such as Wallpaper Engine) to fill that gap. This degree of extensibility is unique to Windows. Android Live wallpapers have been introduced in Android 2.0 Eclair to provide native support for animated wallpapers. From a technical point of view, live wallpapers are software applications that provide a moving background image and may allow for user interaction or utilize other hardware and software features within the device (accelerometer, GPS, network access, etc.). macOS and iOS macOS has built-in support, via the Desktop & Screen Saver panel in its System Preferences/Settings, for cycling through a folder collection of images on a timed interval or when logging in or waking from sleep. Since macOS Mojave, the user can also select a "Dynamic Desktop" that automatically updates to visually match the time of the day. Additionally, macOS has the native ability to run a screen saver on the desktop; in this configuration, the screen saver appears beneath the desktop icons in place of the system wallpaper. However, macOS does not feature a built-in interface to do this; it must be done through Terminal commands or various third-party applications. Dynamically animated backgrounds have also been introduced in iOS 7 and later versions, however they are restricted to the ones provided by Apple. Jailbroken iOS devices can download other dynamic backgrounds. Linux distributions Linux distributions usually provides their own original backgrounds. For example: • Debian puts many alternative backgrounds under the /usr/share/backgrounds directory. • GNOME 2 can be set to cycle through pictures from a folder at regular intervals, similarly to Windows 7. • MATE provides various wallpapers, usually in the /usr/share/backgrounds/mate directory. • KDE version 4 and later provide various dynamic wallpapers, including a slideshow, and other options provided by plugins, such as fractals and Earth map. • Enlightenment v17 supports image sequences, animated and interactive desktop backgrounds in its default configuration. ==See also==
