What Are Windows Icons?
Numerous independent vendors are supplying custom icons in sizes and resolutions common to certain computer platforms. The article explains what icons are, how they are used and implemented in various systems, and what standards are defined for Windows icons, Mac icons, and PNG icons.Computer icons are an integral part of any graphical user interface. Icons are small pictures of standard resolutions that visually represent objects, actions, and symbols. In window-based systems, icons are used as a faster, more intuitive way to communicate with the user. Icons representing typical elements of a user interface are better visible than text, can be recognized faster, and are easier for new computer users.
Originally introduced in 1970 by the Xerox Research Center and widely deployed by the Mac OS and Microsoft Windows platforms, icons make computer novices feel more comfortable with operating systems, learn faster and work more efficiently. Icons can be used to replace or supplement text messages. Commonly used in menus, toolbars, on buttons and in new ribbon-type user interfaces, icons have come a long way from the original concept.
There are multiple image formats for storing icons. The Windows systems use Windows icons in the platform-specific ICO format. Mac OS computers use Mac icons in their specific formats, while Unix-based systems use PNG icons for most applications. As such, icon software is generally available for the Windows and Mac OS systems, while Unix users can create their icons with just about any image editor.
Generally speaking, icons are square pictures that come in a number of standard sizes and color resolutions. Most systems support icon sizes of 16x16 to 128x128 pixels, while some platforms readily accept icon images as large as 512x512 pixels. The large 512x512 pixel icons were first used in Mac OS Leopard.
Pixel resolutions of all icons are operating system dependent. For example, Windows icons are specified as images in 16 and 256-color gammas as well as True Color images with alpha channel. Windows icons come in standard sizes of 16x16, 32x32, and 48x48 pixels. Windows Vista implements new standards for Windows icons, including icons in resolutions of up to 256x256 pixels in True Color only. Optionally, icons of 128x128 and 512x512 pixels are supported. Interestingly, the higher resolution versions of Windows Vista icons are stored in compressed PNG format instead of Windows ICO used in previous versions of Windows and for lower resolution icons. Other platforms such as Windows Mobile can employ standard icons of other sizes, e.g. 24x24 pixels.
Many independent designers are offering custom icons. Aha-Soft offers a variety of Windows icons, Mac icons, and PNG icons in all sizes and resolutions standard to those platforms. The company provides royalty-free icons individually and in matching sets incorporating icons drawn a common style or theme.
