| Class | public class FLARLoaderSource |
| Inheritance | FLARLoaderSource  flash.display.Sprite |
| Implements | IFLARSource |
Loader as a source image for tracker target detection.
FLARLoaderSource samples the contents of a Loader against a white background,
to provide maximum contrast for marker detection.
This class can be used for testing marker detection without a camera,
for example with a swf or jpeg with valid patterns within.
| Property | Defined By | ||
|---|---|---|---|
| inited : Boolean [read-only]
Returns true if initialization is complete. | FLARLoaderSource | ||
| mirrored : Boolean
FLARLoaderSource cannot be mirrored;
method is here only for compliance with IFLARSource. | FLARLoaderSource | ||
| source : BitmapData [read-only]
Retrieve the BitmapData source used for analysis. | FLARLoaderSource | ||
| sourceDirty : Boolean [read-only]
FLARLoaderSource always returns true, to ensure tracking happens every frame. | FLARLoaderSource | ||
| sourceSize : Rectangle [read-only]
Size of BitmapData source used for analysis. | FLARLoaderSource | ||
| trackerToDisplayRatio : Number [read-only]
Ratio of area of tracker's reported results to display size. | FLARLoaderSource | ||
| Method | Defined By | ||
|---|---|---|---|
FLARLoaderSource(contentPath:String, displayWidth:Number, displayHeight:Number, trackerToSourceRatio:Number = 0.5)
Constructor. | FLARLoaderSource | ||
dispose():void
Halts all processes and frees this instance for garbage collection. | FLARLoaderSource | ||
update():void
Update the BitmapData source used for analysis. | FLARLoaderSource | ||
| inited | property |
inited:Boolean [read-only]
Returns true if initialization is complete.
FLARLoaderSource is inited automatically in constructor.

public function get mirrored():Boolean public function set mirrored(value:Boolean):void| source | property |
source:BitmapData [read-only] Retrieve the BitmapData source used for analysis. NOTE: returns the actual BitmapData object, not a clone.
public function get source():BitmapData| sourceDirty | property |
sourceDirty:Boolean [read-only]
FLARLoaderSource always returns true, to ensure tracking happens every frame.
public function get sourceDirty():Boolean| sourceSize | property |
sourceSize:Rectangle [read-only] Size of BitmapData source used for analysis.
public function get sourceSize():Rectangle| trackerToDisplayRatio | property |
trackerToDisplayRatio:Number [read-only] Ratio of area of tracker's reported results to display size. Use to scale (multiply) results of tracker analysis to correctly fit display area.
public function get trackerToDisplayRatio():Number| FLARLoaderSource | () | Constructor |
public function FLARLoaderSource(contentPath:String, displayWidth:Number, displayHeight:Number, trackerToSourceRatio:Number = 0.5)Constructor.
ParameterscontentPath:String — Filename to load.
| |
displayWidth:Number — Width at which to display video.
| |
displayHeight:Number — Height at which to display video.
| |
trackerToSourceRatio:Number (default = 0.5)1.0 results in no downsampling;
A value of 0.5 (the default) downsamples the camera input by half.

public function update():void
Update the BitmapData source used for analysis.
