What Are Mac Icons?
Many independent vendors are providing custom icons in sizes and resolutions standard to certain systems. 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 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 common 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 platforms, icons make new users 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-type user interfaces, icons have come a long way from the original concept.
There are multiple image formats for storing icons. Microsoft Windows systems store Windows icons in the platform-dependent ICO format. Mac OS systems 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 Apple systems, 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 used in Mac OS Leopard.
Pixel resolutions of all icons are operating system dependent. For example, Windows icons are specified as images in 16 and 256-color gammas as well as True Color pictures with alpha channel. Windows icons come in standard resolutions 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 icons. Other platforms such as Windows Mobile can employ standard icons of other sizes, such as 24x24 pixels.
Numerous 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.
