What Are Windows Icons?
Numerous independent vendors are offering custom icons in sizes and resolutions standard to certain computer platforms. The article explains what icons are, how they are used and implemented in various systems, and what standards exist for Windows icons, Mac icons, and PNG icons.Computer icons are an integral part of any graphical user interface. Icons are small pictograms of standard sizes 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 standard elements of a user interface are better visible than text, can be recognized faster, and are easier for new computer users.
Originally developed in 1970 by the Xerox Research Center and widely deployed by the Mac OS and Microsoft Windows systems, icons make new users feel more comfortable with operating systems, learn quicker and interact more efficiently. Icons can be used to replace or supplement text messages. Widely used in menus, toolbars, on buttons and in new ribbon-style user interfaces, icons have come a long way from the original concept.
There are multiple graphic formats for storing icons. Microsoft Windows systems store Windows icons in the platform-specific ICO format. Apple Macintosh systems store Mac icons in their specific formats, while Unix-based systems use PNG icons for most applications. As such, icon editing software is generally available for the Windows and Mac OS systems, while Unix users can design PNG icons with any image editor.
As a rule of thumb, icons are square pictograms that come in a number of standard sizes and color resolutions. Most platforms use icons of 16x16 to 128x128 pixels, while some platforms readily accept icon images as large as 512x512 pixels. The large 512x512 pixel icons were first employed in Mac OS Leopard.
Pixel dimensions of all icons are operating system dependent. For example, Windows icons are defined as images in 16 and 256-color gammas as well as True Color images with alpha channel. Windows icons are supplied in standard sizes of 16x16, 32x32, and 48x48 pixels. Windows Vista defines new standards for Windows icons, including icons in resolutions of up to 256x256 pixels in True Color only. Optionally, images of 128x128 and 512x512 pixels are supported. Interestingly, the high-resolution Windows Vista icons are stored in compressed PNG format instead of Windows ICO used in previous versions of Windows and for lower resolution images. Other platforms such as Windows Mobile can use standard icons of other sizes, e.g. 24x24 pixels.
