| Attributes | ||||
| Name | Required | Request-time | Type | Description |
| align | false | false | javax.el.ValueExpression
(must evaluate to java.lang.String)
| Deprecated. This attribute specifies the position of an IMG, OBJECT, or APPLET with respect to its context. The possible values are "bottom", "middle", "top", "left" and "right". The default value is "middle". |
| alt | false | false | javax.el.ValueExpression
(must evaluate to java.lang.String)
| For compability with XHTML 1.1 standart |
| bgcolor | false | false | javax.el.ValueExpression
(must evaluate to java.lang.String)
| Background color of painted image. Default value is 'transparent' which means no background fill. Hex colors can be used, as well as common color names. Invalid values are treated as transparent. Note, that JPEG format doesn't support transparency, and transparent background is painted black. Also note, that several browsers (e.g. IE6) do not support PNG transparency. Default value is "transparent" |
| binding | false | false | javax.el.ValueExpression
(must evaluate to javax.faces.component.UIComponent)
| The attribute takes a value-binding expression for a component property of a backing bean |
| border | false | false | javax.el.ValueExpression
(must evaluate to java.lang.String)
| Deprecated. This attribute specifies the width of an IMG or OBJECT border, in pixels. The default value for this attribute depends on the user agent |
| cacheable | false | false | javax.el.ValueExpression
(must evaluate to boolean)
| Supported (or not) client/server caching for generated images. Caching on client supported by properly sending and processing of HTTP headers (Last-Modified, Expires, If-Modified-Since, etc.) Server-side caching is supported by application-scope object cache. For build of cache key use "value" attribute, serialized to URI |
| data | false | false | javax.el.ValueExpression
(must evaluate to java.lang.Object)
| Value calculated at render time and stored in Image URI (as part of cache Key), at paint time passed to a paint method. It can be used for updating cache at change of image generating conditions, and for creating paint beans as "Lightweight" pattern components (request scope). IMPORTANT: Since serialized data stored in URI, avoid using big objects |
| format | false | false | javax.el.ValueExpression
(must evaluate to java.lang.String)
| format Name of format for sending a generated image. It currently supports "jpeg" (24 bit, default), "gif" (8 bit with transparency), "png" (32 bit with transparency) |
| height | false | false | javax.el.ValueExpression
(must evaluate to int)
| Height in pixels of image (for paint canvas and HTML attribute). Default value is "10". |
| hspace | false | false | javax.el.ValueExpression
(must evaluate to java.lang.String)
| Deprecated. This attribute specifies the amount of white space to be inserted to the left and right of an IMG, APPLET, or OBJECT. The default value is not specified, but is generally a small, non-zero length |
| id | false | false | java.lang.String | Every component may have a unique id that is automatically created if omitted |
| lang | false | false | javax.el.ValueExpression
(must evaluate to java.lang.String)
| Code describing the language used in the generated markup for this component |
| paint | false | false | javax.el.MethodExpression
(signature must match void paint(java.awt.Graphics2D,java.lang.Object))
| The method calls expression to paint Image on prepared Buffered image. It must have two parameters with a type of java.awt.Graphics2D (graphics to paint) and Object (restored from URI "data" property). For painting used 32-bit RGBA color model (for 8-bit images used Diffusion filtration before sending) |
| rendered | false | false | javax.el.ValueExpression
(must evaluate to boolean)
| If "false", this component is not rendered |
| style | false | false | javax.el.ValueExpression
(must evaluate to java.lang.String)
| CSS style rules to be applied to the component |
| styleClass | false | false | javax.el.ValueExpression
(must evaluate to java.lang.String)
| Assigns one or more CSS class names to the component. Corresponds to the HTML "class" attribute. |
| title | false | false | javax.el.ValueExpression
(must evaluate to java.lang.String)
| Advisory title information about markup elements generated for this component |
| value | false | false | javax.el.ValueExpression
(must evaluate to java.lang.Object)
| The current value of this component |
| vspace | false | false | javax.el.ValueExpression
(must evaluate to java.lang.String)
| Deprecated. This attribute specifies the amount of white space to be inserted above and below an IMG, APPLET, or OBJECT. The default value is not specified, but is generally a small, non-zero length |
| width | false | false | javax.el.ValueExpression
(must evaluate to int)
| Width in pixels of image (for paint canvas and HTML attribute). Default value is "10". |
| Variables | No Variables Defined. |
