What is a desktop wallpaper?



Definition: A computer wallpaper is an image used as desktop background on a computer screen.

 

The wallpaper is commonly used in Microsoft Windows, Macintosh Mac OS, Linux, and in other operating systems. The term used in Windows is desktop background or wallpaper, and in Mac OS is desktop picture. Prior to Windows Vista, only BMP or JPG images were recognized. However, with introduction of Windows Vista and Windows 7 the following file formats are recognized: JPEG, GIF, BMP, PNG and TIF.

Screen resolution is the number of dots (pixels) on the entire screen. For example, a 640x480 pixel screen is capable of displaying 640 distinct dots on each of 480 lines, which are about 300,000 pixels (0.3MegaPixels).
The most common screen resolutions are: 1920x1600, 1440x1280, 1280x1024, and 1024x768.
Please note that setting small images as wallpaper for your desktop will enlarge them too much and the picture will look pixelated.

 

Position options:

When you set a background picture on your desktop you have 3 positioning options: tile, center, or stretch.

 

Stretch - you must manually choose it for those pictures closer to your screen resolution. If the picture is too small, when you apply stretch settings it will be distorted.  BioniX Desktop Changer, which automatically resizes the picture to fit your desktop with one of its smart functions. This smart function allows you to:

  • Enlarge small wallpapers until one border touches the edges of the screen
  • Enlarge small wallpapers with no more than x% so the picture won’t look pixelated

Smart background color

Another amazing feature available ONLY in BioniX is the Smart background color: the program can analyze the wallpaper and determine your desktop background color in order to blend the image into the background seamlessly. If the wallpaper doesn't have a predominant color the program can fade wallpaper's borders to black using a smart fade effect.

Aspect ratio

Aspect ratio is the proportional relationship between image's width and its height . For example a monitor with a height of 9 inches will have a width of 16 inches.
Five common aspect ratios are: 3:2(aspect ratio found in photography, old digital cameras), 4:3 (old CRT monitors, old digital cameras), 16:9 and 16:10 (modern LCD monitors), 1.85:1, 2.39:1 (cinemas).
Please note that in Microsoft Windows, using wallpapers with an aspect ratio different than the aspect ratio of your screen will distort them. However, BioniX Background Changer has a feature called ‘Smart Enlarge’ that allows it to fit a wallpaper on your entire desktop/monitor without distorting it.

 

 

Setting your wallpaper

You can set on your desktop any kind of pictures: family, travel, holidays, animals and pets, favorite vacation, celebrities, and even abstract arts that you admire, also your desktop wallpapers can refer to specific the time of year (holidays (like Christmas), summer, winter), your mood, etc... And if you are tired of the plain background and simple pictures you can set animated wallpapers on your desktop like rain showers, screen bubbles, billowing wind, movie scenes, etc.
To customize your computer you can choose personal pictures to set them as wallpaper. Under Windows XP/Vista/7 this can be done by navigating to the folder where your photos are stored and right-clicking on any image file. This will display a pop-up menu. Choose Preview to open a slide-show window to cycle through the images in the folder. Find the picture you want to use as desktop wallpaper, right-click on it and choose Set as desktop background.
