What Are Mac 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 designed and implemented in various systems, and what standards are defined for Windows icons, Mac icons, and PNG icons.Computer icons are incorporated into any graphical user interface. Icons are small pictures of standard 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 typical elements of a user interface are better visible than text, can be recognized faster, and are certainly easier on the eyes.
Originally developed in 1970 by the Xerox Research Center and widely popularized by the Apple Macintosh and Microsoft Windows systems, 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 multiple image formats for storing icons. Microsoft 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 Mac OS platforms, while Unix users can create their icons with just about any image editor.
Generally speaking, icons are square images that come in a number of standard sizes and color resolutions. Most platforms support icons of 16x16 to 128x128 pixels, while some platforms readily accept icons as large as 512x512 pixels. The high-resolution 512x512 pixel icons were first used in Mac OS Leopard.
Pixel dimensions of all icons are operating system 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 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 older versions of Windows and for lower resolution images. Other systems such as Windows Mobile can employ standard icons of other sizes, e.g. 24x24 pixels.
Many independent vendors are offering custom icons. Aha-Soft offers a wide selection of Windows icons, Mac icons, and PNG icons in all sizes and resolutions standard to those platforms.
