Compatible Icons
4/19/2010
Windows Mobile devices use different icon sizes than that of desktop computers. In addition, the Windows Mobile devices support screens with various resolutions. Therefore, your application should contain icons designed for all supported resolutions. Windows Mobile stretches or compresses icons to fit the resolution of the screen. However, this frequently results in aliasing. The following illustration shows a correctly sized icon and a stretched icon.
