For other uses, see Icon (disambiguation). For a list of icons for use on Wikipedia, see Wikipedia:Icons.On computer displays, a computer icon is a small pictogram. Icons have been used to supplement the normal alphanumerics of the computer. Modern computers now can handle bitmapped graphics on the display terminal, so the icons are widely used to assist users.
A computer icon usually ranges from 16 by 16 pixels up to 128 by 128 pixels. Some upcoming OSs will feature icons up to 512 by 512 pixels. When the graphical output device has a smaller size, the icon size is small. Vision impaired users (due to such conditions as poor lighting, tired eyes, medical impairments, bright backgrounds, or color blindness) may need to utilize the self-selected icon size options.
Icons may represents a file, folder, application or device on a computer operating system. In modern usage today, the Icon can represent anything that the users want it to: any macro command or process, mood-signalling, or any other indicator. User friendliness also demands error-free operation, where the icons are distinct from each other, self explanatory, and easily visible under all possible user setups.
Icons were first developed as a tool for making computer interfaces easier for novices to grasp in the 1970s at the Xerox Palo Alto Research Center facility. Icon-driven interfaces were later popularized by the Apple Macintosh and Microsoft Windows operating environments.
Icons may also be found on the desktop, toolbars and in the menus of computer application software such as Microsoft Word. Icons are made more use-friendly by being very clear from every other icon. Each Icon-set may also have unifying features that show that similar icons are related to each other. Icons show this by:
- Contrasting Sizes
- Dark-Light
- Square-grabbing (large or small area, top/ bottom, left/ right, centred/ perimeter)
- Pattern-contrast (Horizontal-striped, Vertical-striped, Slanted-stripes, Circles, Oblongs, ...)
- Light-On-Dark, or Dark-On-Light
- Framed/ Shadowed (or not)
- Color contrasts (red, orange, blue, green, etc)
- Fine-detail filled (with thin lined drawings), or NOT.
- Animated ... but use very carefully!
Virtually every major computer operating system has the ability to use an icon-based graphical user interface (GUI) to display information to end users.
Function or program icons
[编辑]
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.
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
[编辑]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.
Designing icons
[编辑]In most situations, icons must be small so they do not intrude on an application's workspace. This results in a limited message space, reductions in recognition potential, and severe design constraints. It can often be extremely difficult to find sets of icons that are useful across many different cultures. Creating icons for every function can also prove problematic. In many modern computer-based applications, system functionality is extremely high. The use of many functions can mean the design of many icons. In addition, the communicativeness of icons can have major effects on both their learnability and their memorability. If an icon is highly communicative, then it is much more likely to be easy to learn. In addition, icons that are easy to learn will generally be highly memorable.

把IconMaster单独列出
[编辑]条目中IconMaster似乎一个硬件设备。我在网上搜索一下，找到的更多是作为一个图标软换软件出现的。无论是哪种情况，都应该单独列出吧？
主控圖標系統(IconMaster)
[编辑]IconMaster把多層圖標功能與高安全性的主控功能結合在一起，適用於從自動控制到手動控制的所有播出環節。重要的是IconMaster是目前唯一的SD/HD可切換播出切換台，從SD升級到HD時不需要任何的投資。當應用的需求改變時，IconMaster的模組化結構，可以最靈活地更改系統結構。它僅僅佔用兩個插槽，在3RU的NEO機箱中仍有10個插槽可供將來升級。 IconMaster以Leitch的NEO平台為基礎，是唯一可以和其他高階應用模組結合使用的主控圖標系統。IconMaster迎合未來需要的設計，不僅可以使用戶能夠將IconLogo升級到IconMaster，而且還可以和IconStation緊密地結合使用，以得到超級的圖文和動畫效果。除此之外IconMaster還具有增強的控制、靈活性以及高階鍵控等特點。
它的一些主要功能如下： 1.可嵌入圖標的12組HD/SD輸入主控台 2.全面的預覽功能 3.靈活的16頻道內建數位信號處理(HD） 4.2路獨立的立體聲音頻輸入 5.全功能的設備控制 6.內建的功能—4層圖標引擎、靜態或動態圖標、指針或數字時鐘、滾動字幕和緊急報警、音頻片段(WAV）的重播 7.6個keyer—2個外置和4個內置 8.可控內部矩陣（NEO、NSM）和外部矩陣（Platinum、Integrator、Integration、Gold、Panaces或第三方的矩陣） 9.支援NUCLEUS控制面板
