Mac OS X allows continuous scaling of icons up to 128x128 pixels

Function or program icons

Most computer functions in a GUI are represented by a function icon. Placing the cursor on the icon, and clicking (or double-clicking) a mouse, trackball or other button usually starts the function or program.

The creation of a good function icon can be considered as an art form in itself, comparable to that practiced in the past in the domain of miniature painting by old masters such as Joseph Severn and Charles-Francois Daubigny.

Charles_François Daubigny (portrait by Nadar) Charles-François Daubigny (Paris, February 15, 1817 - Paris, February 19, 1878) was one of the painters of the Barbizon school, and is considered an important precursor of impressionism. ...


The icon must be original, distinctive, and tiny and it must be useful on a wide variety of monitors set at different resolutions. This work is further complicated by the need to create several sets of function icons for several types of views in several types of operating systems, for any given program. For instance, the GUI guidelines in one operating system might specify the need to create sets of 16, 32, and 48 pixel icons for any program while the GUI guidelines in another system might specify sets of 16, 24, 48 and 96 pixel icons for any program.


Document icons

In certain views of folders or directories in a GUI all the documents or files are represented as icons, in addition to their file name and, in certain cases, other details. In most systems and for most files these icons are generic images, representing the program used to create the file, or the file type. In this case, the comments made in the previous paragraph concerning the icon as an art form also apply to file icons.


In the case of graphic files most modern systems replace the generic icon with a reduced image of the graphic. This reduced image usually fits into a 128 by 128 or a 117 by 117 pixel box, depending on the operating system used. It is available in a "thumbnail view" or within some other specialized viewing area on the screen.


The most recent systems and the most recent applications often generate such reduced images from other types of files in programs which have not been traditionally viewed as "graphics," such as word processor software, text files, or business presentation programs such as Agnubis, Impress, or PowerPoint. A word processor (also more formally known as a document preparation system) is a computer application used for the production (including composition, editing, formatting, and possibly printing) of any sort of viewable or printed material. ...
