| Class | public class ImageRenderTarget |
| Inheritance | ImageRenderTarget  mx.core.UIComponent |
A UIComponent that displays images rendered using a command of type IRenderCommand. The application can use any number of ImageRenderTarget objects and update the image they display by using render commands (any implementation of the IRenderCommand interface, like the RenderCommand class).
If the resolution of the rendered image is not equal to the resolution of the ImageRenderTarget object then the image will be scaled automatically. Use the smoothScaling property to enable/disable using smoothing when scaling the image. This property has no effect if scaling is not needed.
The ImageRenderTarget can either be placed as a visible component in the application or it can be used to obtain the rendered image as a BitmapData object . To use it this way, create an ImageRenderTarget, add a RenderCommand with this object as the target, and call ImageRenderTarget.cloneBitmapData() in the response handler of the RenderCommand.
