Class TLcdContrastIcon

java.lang.Object
com.luciad.gui.swing.TLcdContrastIcon
All Implemented Interfaces:
ILcdIcon, ILcdCloneable, Serializable, Cloneable
public class TLcdContrastIcon extends Object implements ILcdIcon, Cloneable

A contrasted/brightened version of an icon.

The contrast value modifies the contrast of the delegate icon. For example

  • A contrast value of 0.0 maps all r, g and b values to 128 (grey).
  • A contrast value of 0.5 maps the r, g and b ranges [0, 256) on [64, 192), so there is less contrast
  • A contrast value of 1.0 doesn't modify the icon.
  • A contrast value of 2.0 maps the r, g and b ranges [0, 64) on 0, [64, 192) on [0, 256) and [192, 256) on 255, So there is more contrast than in the original icon.

The brightness value is applied on the icon after applying the contrast value. It multiplies the r, g and b values with the brightness value. For example

  • A brightness value of 0.0 makes the icon black.
  • A brightness value of 1.0 doesn't modify the icon.
  • A brightness value of 2.0 makes the icon twice as bright.

Notice that this class is not guaranteed to work correctly with non-static icons.

      Parameters:
      c - a Component to retrieve properties from.
      g - the Graphics on which the icon will be painted.
      x - the x position where the icon will be painted. x is the first coordinate of the top left corner point of the icon.
      y - the y position where the icon will be painted. y is the second coordinate of the top left corner point of the icon.

      Makes Object.clone() public.

      When for example extending from java.lang.Object, it can be implemented like this: 
      
 public Object clone() {
   try {
     return super.clone();
   } catch ( CloneNotSupportedException e ) {
     // Cannot happen: extends from Object and implements Cloneable (see also Object.clone)
     throw new RuntimeException( e );
   }
 }
      Specified by:
      clone in interface ILcdCloneable
      Overrides:
      clone in class Object
