What Are Mac Icons?
Numerous independent vendors are providing custom icons in sizes and resolutions common to certain computer platforms. The article explains what icons are, how they are designed and implemented in various platforms, 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 pictures of standard sizes that depict objects, actions, and symbols. In graphical user interfaces, icons are used as a quicker, 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 developed in 1970 by the Xerox Research Center and widely popularized by the Apple Macintosh and Microsoft Windows platforms, icons make computer novices feel more comfortable with computer systems, learn faster and interact more efficiently. Icons can be used to replace or supplement text messages. Widely used in menus, toolbars, on buttons and in the latest ribbon-type user interfaces, icons have come a long way from the original concept.
There are multiple image formats for storing icons. Microsoft Windows systems use Windows icons in the platform-dependent ICO format. Mac OS systems use Mac icons in their specific formats, while Unix-based systems employ PNG icons for most applications. As such, icon editing software is generally available for the Windows and Apple platforms, while Unix users can design their icons with any image editor.
Generally speaking, icons are square pictures that come in a number of standard sizes and color resolutions. Most systems use icon sizes of 16x16 to 128x128 pixels, while some platforms readily accept icon images as large as 512x512 pixels. The ultra-high definition 512x512 pixel icons were first used in Mac OS Leopard.
Pixel dimensions of all icons are platform dependent. For example, Windows icons are specified as pictures in 16 and 256-color gammas as well as True Color pictures 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 sizes of up to 256x256 pixels in True Color only. Optionally, icons 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, such as 24x24 pixels.
