Icon Naming Specification #
Publication Date: February 15 2006, Version: Version 0.7
1 Overview #
The Icon Theme Specification has been in use now for a while, in several desktops, including KDE and Gnome. However, there has never been any centralized direction on how to name the icons that are available for use by applications, when creating a theme. This has meant that artists have historically had to duplicate many icons, in order for their themes to work across desktop environments.
This specification aims to solve this problem, by laying out a standard naming scheme for icon creation, as well as providing a minimal list of must have icons, and a larger list with many more examples to help with the creation of extended icons for third party applications, devices, and new MIME types.
2 Context #
The list of default Contexts for the icon theme are:
Table 1: Standard Contexts #
| Name | Description | Directory |
|---|---|---|
| Actions | Icons which are generally used in menus and dialogs for interacting with the user. | actions |
| Animations | Animated images used to represent loading web sites, or other background processing which may be less suited to more verbose progress reporting in the user itnerface. | animations |
| Applications | Icons that describe what an application is, for use in the Programs menu, window decorations, and the task list. These may or may not be generic depending on the application and its purpose. Applications which are to be considered part of the base desktop, such as the calculator or terminal, should use the generic icons specified in this specification, while more advanced applications such as web browsers and office applications should use branded icons which still give the user an idea of what function the application provides. | apps |
| Categories | Icons that are used for categories in the Programs menu, or the Control Center, for separating applications, preferences, and settings for display to the user. | categories |
| Devices | Icons for hardware that is contained within or connected to the computing device. | devices |
| Emblems | Icons for tags and properties of files, that are displayed in the file manager. This context contains emblems for such things as “read-only” or “photos”. | emblems |
| Emotes | Icons for emotions that are expressed through text chat applications such as :-) or :-P in IRC or instant messengers. | emotes |
| International | Icons for international denominations such as flags. | intl |
| MimeTypes | Icons for different types of data, such as audio or image files. | mimetypes |
| Places | Icons used to represent locations, either on the local filesystem, or through remote connections. Folders, trash, and workgroups are some examples. | places |
| Status | Icons for presenting status to the user. This context contains icons for warning and error dialogs, as well as for the current weather, appointment alarms, and battery status. | status |
3 Icon Naming Guidelines #
Here we define some guidelines for when creating new icons that extend the standardized list of icon names defined here, in order to provide icons for more specific MIME types, devices, or international flags.
Icon names are in the en_US.US_ASCII locale. This means that the allowable characters in the icon names, must fall withing the US-ASCII character set. As a further restriction, all icon names may only contain lowercase letters, numbers, underscore, dash, or period characters. Spaces, colons, slashes, and backslashes are not allowed. Also, icon names must be spelled as they are in the en_US dictionary.
The dash “-” character is used to separate levels of specificity in icon names, for all contexts other than MimeTypes. For instance, we use “input-mouse” as the generic item for all mouse devices, and we use “input-mouse-usb” for a USB mouse device. However, if the more specific item does not exist in the current theme, and does exist in a parent theme, the generic icon from the current theme is preferred, in order to keep consistent style.
Icons for branded applications should be named the same as the binary executable for the application.
4 Standard Icon Names #
This section describes the standard icon names that should be used by artists when creating themes, and by developers when writing applications which will use the Icon Theme Specification.
