What Are Mac Icons?
Numerous independent vendors are offering 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 an integral part of any graphical user interface. Icons are small pictures of standardized resolutions that depict objects, actions, and other concepts. In graphical user interfaces, icons are used as a faster, more intuitive way to communicate with the user. Icons representing standard elements of a user interface are more visually appealing than text, can be recognized faster, and are certainly easier on the eyes.
Originally introduced in 1970 by the Xerox Research Center and widely deployed by the Apple Macintosh and Microsoft Windows platforms, icons make computer novices feel more comfortable with computer systems, learn quicker and work more efficiently. Icons can be employed to replace or supplement text commands. 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 image formats for storing icons. The Windows systems store 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 editing software is generally available for the Windows and Mac OS platforms, while Unix users can create PNG icons with just about any image editor.
As a rule of thumb, icons are square pictures that come in a variety of standard sizes and color resolutions. Most platforms support icons of 16x16 to 128x128 pixels, while some systems readily accept icons as large as 512x512 pixels. The large 512x512 pixel icons were first employed 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 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, 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 images. Other platforms such as Windows Mobile can use standard icons of other resolutions, e.g. 24x24 pixels.
Many independent designers are providing custom icons. Aha-Soft offers a wide selection of Windows icons, Mac icons, and PNG icons in all sizes and resolutions common to those platforms.
