Image class displays an image.
It can display an image by using a URL to an image, a Bitmap instance or a BitmapData instance.

Sets the x and y position of the component. | UIComponent | |
| validateDisplayList():void
Validates the display list of the component by calling the updateDisplayList(). | UIComponent | |
| validateNow():void
Validates the component immediately by calling validateProperties(), validateSizes(), and validateDisplayList() if necessary. | UIComponent | |
| validateProperties():void
Validates the properties of the component by calling the commitProperties() method. | UIComponent | |

pixelSnapping:String
Controls whether or not the Bitmap object is snapped to the nearest pixel. The PixelSnapping class includes possible values:
PixelSnapping.NEVER—No pixel snapping occurs.PixelSnapping.ALWAYS—The image is always snapped to the nearest pixel, independent of transformation.PixelSnapping.AUTO—The image is snapped to the nearest pixel if it is drawn with no rotation or skew and it is drawn at a scale factor of 99.9% to 100.1%. If these conditions are satisfied, the bitmap image is drawn at 100% scale, snapped to the nearest pixel. Internally, this value allows the image to be drawn as fast as possible using the vector renderer. public function get pixelSnapping():String public function set pixelSnapping(value:String):void| smoothing | property |
smoothing:Boolean
Controls whether or not the bitmap is smoothed when scaled. If true, the bitmap is smoothed when scaled. If false, the bitmap is not smoothed when scaled.

public function Image()
Constructs an Image instance.
| setImage | () | method |
public function setImage(image:Object):void
Sets the image.
The image parameter can be of type String as a URL to an external image, Bitmap instance, a BitmapData instance or a URLRequest instance.
Parameters
image:Object — The image to be set.
