What Are Windows Icons?
Numerous independent vendors are providing custom icons in sizes and resolutions standard to certain systems. 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 an integral part of any modern GUI. Icons are small pictograms of standard sizes that depict objects, actions, and symbols. In window-based systems, icons are used as a quicker, more intuitive way to communicate with the user. Icons depicting common elements of a user interface are better visible than text, can be recognized faster, and are easier for new computer users.
Originally introduced in 1970 by the Xerox Research Center and widely deployed by the Apple Macintosh and Microsoft Windows systems, icons make new users feel more comfortable with computer systems, learn faster and interact more efficiently. Icons can be employed to replace or supplement text messages. Widely 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 file formats for storing icons. The Windows systems store Windows icons in the platform-specific ICO format. Apple Macintosh computers store Mac icons in their specific formats, while Unix-based systems employ PNG icons for most applications. As such, icon editing software is generally available for the Windows and Mac OS systems, while Unix users can create PNG icons with just about any image editor.
Generally speaking, icons are square pictograms that come in a number of standard sizes and color resolutions. Most platforms use 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 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 implements 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 use standard icons of other sizes, such as 24x24 pixels.
Numerous independent vendors are providing custom icons. Aha-Soft offers a variety of Windows icons, Mac icons, and PNG icons in all sizes and resolutions common to those platforms. The company sells royalty-free icons individually and in matching sets that include icons drawn a common style or theme.
