Classpublic final class CarryThreshold
ImplementsIFilter

The CarryThreshold class transforms a grayscale image into binary color-space using a carry flag.

The filter checks each pixel and adds the brightness to the carry flag. If the flag is greater than a threshold value of 0x7f the pixel will be set to 1 otherwise to 0.

The formula of this filter is new = ( flag += old > threshold ) ? 1, flag -= 0xff : 0.

Supported formats:
This is a conversion filter so there are no supported formats.


Example 
  
  // Set the conversion filter to CarryThreshold
  Image.threshold = new CarryThreshold();
  
  var video: WebCam = new WebCam( 160, 120 );
  var image: Image = new Image( 160, 120, ImageFormat.BINARY );
  
  image.loadBitmapData( video.getCurrentFrame(), true );
