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 used and implemented in various platforms, and what standards are defined for Windows icons, Mac icons, and PNG icons.Computer icons are incorporated into any modern GUI. Icons are small pictures of standard resolutions that visually represent objects, actions, and symbols. In graphical user interfaces, icons are used as a quicker, 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 certainly easier on the eyes.
Originally introduced in 1970 by the Xerox Research Center and widely popularized by the Mac OS and Microsoft Windows systems, icons make computer novices feel more comfortable with computer systems, learn quicker and interact more efficiently. Icons can be used to replace or supplement text messages. Commonly used in menus, toolbars, on buttons and in the latest ribbon-style user interfaces, icons have come a long way from the original concept.
There are several graphic formats for storing icons. The Windows systems use Windows icons in the platform-dependent ICO format. Mac OS systems store 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 Apple platforms, while Unix users can create their icons with any graphic editor.
Generally speaking, icons are square images that come in a variety of standard sizes and color resolutions. Most systems support icon sizes of 16x16 to 128x128 pixels, while some systems readily accept icons as large as 512x512 pixels. The big 512x512 pixel icons were first employed in Mac OS Leopard.
Pixel resolutions of all icons are platform dependent. For example, Windows icons are defined as pictures 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 defines 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 older 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.
