public function Canvas()Constructor
| initFromBitmapData | () | method |
public function initFromBitmapData(data:BitmapData):voidInitializes a canvas object from a BitmapData object. Creates a image data vector and confidence matrix vector from the BitmapData.
Parameters
data:BitmapData — The bitmap data to load into the canvas.
|
| initFromData | () | method |
public function initFromData(imageData:Vector.<Number>, imageWidth:Number, imageHeight:Number):voidInitializes a canvas object from a pre-defined image data vector.
Parameters
imageData:Vector.<Number> — The image data to load into the canvas.
| |
imageWidth:Number — The image width.
| |
imageHeight:Number — The image height.
|
| refresh | () | method |
public function refresh():voidDeprecated helper method that will render the canvas.
| render | () | method |
public function render():voidRenders the entire canvas from the confidence matrix vector and image data vector.
| reset | () | method |
public function reset():voidClears the image back to default.
| update | () | method |
public function update(changed:Vector.<Number>):voidUpdated the canvas based on a vector of updated pixels. This greatly helps with performances if only a small amount of pixels were modified.
Parameters
changed:Vector.<Number> — Vector containing changed pixels.
