Rendered Image Factory

Identifier:
org.eclipse.gmf.runtime.draw2d.ui.render.renderedImageFactory

Since:
GMF 1.0

Description:
This extension point is used to define an image type to allow auto detection of an image buffer. The image type can instantiate an (RenderedImage) which can subsequently be rendered using the (ScalableImageFigure) class. In the extension point, the client points to a factory class which they create implementing the (RenderedImageType) interface. The (RenderedImageFactory) static class calls the extension point to compile a list of image types to query. When the client calls the (RenderedImageFactory) to retrieve the proper (RenderedImage), it will ask each type whether it can handle the particular image buffer. If the image buffer is auto-detected by the type, then the type will instatiate and return a (RenderedImage) object.

Examples:
An extension to the renderedImageFactory would require the implementation of the (RenderedImageType) interface. The following is an example plugin.xml entry for a renderedImageFactory extension:

    <extension 
     point=
"org.eclipse.gmf.runtime.draw2d.ui.render.renderedImageFactory"
>
      <factory 
        class=
"org.eclipse.gmf.runtime.draw2d.ui.render.awt.internal.svg.SVGImageType"
>
      </factory> 
 </extension>
