What Are Mac Icons?
A number of independent vendors are providing custom icons in sizes and resolutions standard 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 incorporated into any graphical user interface. Icons are small pictures of standard sizes that depict objects, actions, and other concepts. In window-based systems, 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 certainly easier on the eyes.
Originally introduced 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 operating systems, learn quicker and work more efficiently. Icons can be used 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 graphic formats for storing icons. Microsoft Windows systems use Windows icons in the platform-specific 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 software is generally available for the Windows and Apple platforms, while Unix users can design their 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 systems support icon sizes of 16x16 to 128x128 pixels, while some systems readily accept icons as large as 512x512 pixels. The ultra-high definition 512x512 pixel icons were first employed in Mac OS Leopard.
Pixel dimensions 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 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 sizes of up to 256x256 pixels in True Color only. Optionally, images 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 systems such as Windows Mobile can use standard icons of other sizes, e.g. 24x24 pixels.
Numerous 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 systems.
