Q: Why does the desktop image appear is if it starts in the middle of the screen?

A: The desktop wallpaper needs to be set to Tile in the Windows Display Properties dialog. Right click on the desktop and select properties to bring up this dialog box. Don't worry about which image is currently selected, it will automatically be set by the Desktop Wallpaper Tool.

Q: What is the aspect ratio and why is it important?

A: The aspect ratio is the ratio of the width of an image to the height. For example a 640x480 image has an aspect ratio of 640 / 480 = 1.333. If you resize an image it is important to maintain the aspect ratio or the image will become distorted.

For example, distortion results if I stretch a 640x480 image (aspect ratio 1.333) to fit a 1280x1024 monitor (aspect ratio 1.25). To properly fill a 1280x1024 screen with a 640x480 image I need to first crop the width of the image to 320 * 1.25 = 400. The 640x400 image will then correctly scale to 1280x1024. Alternatively I can scale the 640x480 image by 2 in both width and height to 1280x960 which maintains the correct aspect ratio but results in a black bar (960 vs 1024 pixels). Centering an image like this still looks quite good, similar to letterboxing in movies.

Q: Where is the desktop image saved?

A: The desktop image is saved in the Desktop Wallpaper Tool directory which is usually
C:\Program files\Desktop Wallpaper Tool\

Q: How much does this program cost?

A: The The Desktop Wallpaper Tool is freeware, which means it is free to use and distribute. If you enjoy this program please consider donating!
