What Are PNG 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 systems, and what standards exist for Windows icons, Mac icons, and PNG icons.Computer icons are incorporated into any modern GUI. Icons are small pictures of standardized sizes that visually represent objects, actions, and symbols. In window-based systems, icons are used as a quicker, 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 deployed 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 used to replace or supplement text messages. 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. The Windows systems store Windows icons in the platform-dependent ICO format. Apple Macintosh 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 Apple systems, while Unix users can create their icons with just about any graphic editor.
Generally speaking, icons are square pictures that come in a number of standard sizes and color resolutions. Most platforms support icon sizes of 16x16 to 128x128 pixels, while some systems readily accept icon images as large as 512x512 pixels. The large 512x512 pixel icons were first employed in Mac OS Leopard.
Pixel resolutions of all icons are operating system dependent. For example, Windows icons are defined as images 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 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 older versions of Windows and for lower resolution images. Other platforms such as Windows Mobile can employ standard icons of other resolutions, such as 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. The company provides royalty-free icons individually and in matching sets that include icons drawn a common style or theme.
