InheritanceCurves Inheritance LUTFilter

The Curves class is a filter that applies a curve to a given image. This curve has to be defined before. In general the curve of the image before transforming it goes from (0x00|0x00) to (0xff|0xff) in a linear way. This means every value from 0x00 to 0xff for the color is mapped with the function f(x) = x.

The curves filter replaces this and each color value will be calculated using f(x) = curve(x).

Supported formats:


Example 
  
  var curve: Curve = new Curve();
  curve.addPoint( new Point( 0x40, 0x80 ) );
  
    var filter: Curves = new Curves( curve );
  
  var image: Image = new Image( 160, 120, ImageFormat.RGB );
  
  filter.apply( image );
