Oracle Fusion Middleware Tag Reference for Oracle ADF Faces 12c (12.2.1.4.0) E81455-03

# <af:activeImage>

af:activeImage activeImage active image

UIComponent class: oracle.adf.view.rich.component.rich.output.RichActiveImage
Component type: oracle.adf.RichActiveImage

The image component renders an image specified by the source property. Due to performance overhead compared to `<af:image>`, you should only use this component if you plan to support changing the source attribute through active data, otherwise you should use the `<af:image>` component.

## Geometry Management

- This component cannot be stretched by a parent layout component.
- This component does not display any children so there are no child stretching capabilities.

this is a test.

## Code Example(s)

    <af:activeImage source="/images/globalhelp.gif"
                    shortDesc="global help"
                    longDescURL="help.html"/>

## Events

Type | Phases | Description
--- | --- | ---
org.apache.myfaces.trinidad.event.AttributeChangeEvent | Invoke, Application, Apply, Request, Values | Event delivered to describe an attribute change. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change event might include the width of a column that supported client-side resizing.

## Attributes

Name | Type | Supports EL? | Description
attributeChangeListener | javax.el.MethodExpression | Only EL | a method reference to an attribute change listener. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.
binding | oracle.adf.view.rich.component.rich.output.RichActiveImage | Only EL | an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean.
clientComponent | boolean | Yes | Default Value: false whether a client-side component will be generated. A component may be generated whether or not this flag is set, but if client Javascript requires the component object, this must be set to true to guarantee the component's presence. Client component objects that are generated today by default may not be present in the future; setting this flag is the only way to guarantee a component's presence, and clients cannot rely on implicit behavior. However, there is a performance cost to setting this flag, so clients should avoid turning on client components unless absolutely necessary. For the components outputText and outputFormatted, setting the clientComponent to true will render id attribute for the html DOM. This ID attribute can alternatively be generated by setting oracle.adf.view.rich.SUPPRESS_IDS to "auto" in web.xml.
customizationId | String | Yes | This attribute is deprecated. The 'id' attribute should be used when applying persistent customizations. This attribute will be removed in the next release.
iconDelivery | String | Yes | Valid Values: auto, reference, inline, fetchAndInline Default Value: auto An attribute specifying ways to render icon. reference - icon will be rendered as "img" tag. inline - svg icon will be rendered inline as "svg" tag fetchAndInline - svg icon will be fetched using XHR and will be rendered inline as "svg" tag. For subsequent requests, svg will be served from browser cache auto - Lets the framework decide the optimal rendering mode. You can use the skinnng property -tr-icon-delivery to override default framework behavior. Skinning property -tr-icon-delivery can be set to any one of "inline/reference/fetchAndInline" modes. However "inline" and "fetchAndInline" modes apply only for svg icons. Details about attribute values "inline" and "fetchAndInline" :- Only svg icons will be inlined. Only context relative and server relative icon URIs are supported Hover, disabled and depressed states should be handled through CSS classes/styles on svg elements. The hoverIcon, disabledIcon and depressedIcon attributes will be ignored.
id | String | No | the identifier for the component. Every component may be named by a component identifier that must conform to the following rules: They must start with a letter (as defined by the Character.isLetter() method) or underscore ( _ ). Subsequent characters must be letters (as defined by the Character.isLetter() method), digits as defined by the Character.isDigit() method, dashes ( - ), or underscores ( _ ). To minimize the size of responses generated by JavaServer Faces, it is recommended that component identifiers be as short as possible. If a component has been given an identifier, it must be unique in the namespace of the closest ancestor to that component that is a NamingContainer (if any).
imageMapType | String | Yes | Valid Values: none, server Default Value: none if a server-side image map is desired, specify "server" and place the image inside a CoreGoLink component. URI of the server-side image map file has to be given as a destination attribute for the goLink component. Default value for imageMapType is "none".
inlineStyle | String | Yes | the CSS styles to use for this component. This is intended for basic style changes. The inlineStyle is a set of CSS styles that are applied to the root DOM element of the component. Be aware that because of browser CSS precedence rules, CSS rendered on a DOM element takes precedence over external stylesheets like the skin file. Therefore skins will not be able to override what you set on this attribute. If the inlineStyle's CSS properties do not affect the DOM element you want affected, then you will have to create a skin and use the skinning keys which are meant to target particular DOM elements, like ::label or ::icon-style.
longDescURL | String | Yes | a URL to a document that contains a long description of the image. This description should supplement the short description.
partialTriggers | String[] | Yes | the IDs of the components that should trigger a partial update. This component will listen on the trigger components. If one of the trigger components receives an event that will cause it to update in some way, this component will request to be updated too. Identifiers are relative to the source component (this component), and must account for NamingContainers. If your component is already inside of a naming container, you can use a single colon to start the search from the root of the page, or multiple colons to move up through the NamingContainers - "::" will pop out of the component's naming container (or itself if the component is a naming container) and begin the search from there, ":::" will pop out of two naming containers (including itself if the component is a naming container) and begin the search from there, etc.
rendered | boolean | Yes | Default Value: true whether the component is rendered. When set to false, no output will be delivered for this component (the component will not in any way be rendered, and cannot be made visible on the client). If you want to change a component's rendered attribute from false to true using PPR, set the partialTrigger attribute of its parent component so the parent refreshes and in turn will render this component.
shortDesc | String | Yes | the short description of the activeImage component. This text is commonly used by user agents as the image's alt text. Note that for accessibility purposes, all images must specify some value for the shortDesc attribute. For purely decorative images which provide no meaningful information, the value should be the empty string.
source | String | Yes | The URI specifying the location of the image resource. SVG icons are also supported, please refer to "iconDelivery" attribute for various SVG embed modes.
styleClass | String | Yes | a CSS style class to use for this component. The style class can be defined in your jspx page or in a skinning CSS file, for example, or you can use one of our public style classes, like 'AFInstructionText'.
unsecure | java.util.Set | Yes | A whitespace separated list of attributes whose values ordinarily can be set only on the server, but need to be settable on the client. Currently, this is supported only for the "disabled" attribute. Note that when you are able to set a property on the client, you will be allowed to by using the the .setProperty('attribute', newValue) method, but not the .setXXXAttribute(newValue) method. For example, if you have unsecure="disabled", then on the client you can use the method .setProperty('disabled', false), while the method .setDisabled(false) will not work and will provide a javascript error that setDisabled is not a function.
visible | boolean | Yes | Default Value: true the visibility of the component. If it is "false", the component will be hidden on the client. Unlike "rendered", this does not affect the lifecycle on the server - the component may have its bindings executed, etc. - and the visibility of the component can be toggled on and off on the client, or toggled with PPR. When "rendered" is false, the component will not in any way be rendered, and cannot be made visible on the client. In most cases, use the "rendered" property instead of the "visible" property. Not supported on the following renderkits: org.apache.myfaces.trinidad.core
