uint start and end values.
Interpolation is done by treating
the start and end values as integers with RGB color channel information in
the least-significant 3 bytes, converting these to HSB values, and
interpolating linearly for each of the h (hue), s (saturation),
and b (brightness) parameters.
Because this interpolator may perform more calculations than a
typical interpolator that is simply interpolating a given type,
specifically to convert the RGB start and end values, this
interpolator provides the option of supplying start and end values
to the constructor. If you specify the start and end RGB values, then
the conversions of these values is calculated once,
and does not need to be done at every future call to
the interpolate() method during the animation.

HSBInterpolator | () | Constructor |
public function HSBInterpolator(startRGB:uint, endRGB:uint)| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 4 |
| Runtimeversies: | Flash Player 10, AIR 1.5 |
Constructor.
The optional parameters for startRGB and
endRGB help to optimize runtime performance by
performing RGB to HSB conversions at construction time, instead of
dynamically with every call to the interpolate() method.
startRGB:uint (default = NaN) | |
endRGB:uint (default = NaN) |
decrement | () | methode |
public function decrement(baseValue:Object, decrementValue:Object):Object| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 4 |
| Runtimeversies: | Flash Player 10, AIR 1.5 |
Returns the result of the two RGB values added together as HSB colors. Each value is converted to an HSB color first, and then each component (hue, saturation, and brightness) is treated individually. The saturation and brightness components are clamped to lie between 0 and 1, and the hue degrees are modulated by 360 to lie between 0 and 360.
Parameters
baseValue:Object — The start value of the interpolation.
| |
decrementValue:Object — The change to apply to the baseValue.
|
Object — The interpolated value.
|
getInstance | () | methode |
public static function getInstance():HSBInterpolator| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 4 |
| Runtimeversies: | Flash Player 10, AIR 1.5 |
Returns the singleton of this class.
Note that the singleton of the HSBInterpolator class might be less useful than separate instances of the class because separate instances can take advantage of precalculating the RGB to HSB conversions for the start and end colors.
Geretourneerde waardeHSBInterpolator — The singleton of the HSBInterpolator class.

increment | () | methode |
public function increment(baseValue:Object, incrementValue:Object):Object| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 4 |
| Runtimeversies: | Flash Player 10, AIR 1.5 |
Returns the result of the two RGB values added together as HSB colors. Each value is converted to an HSB color first, and then each component (hue, saturation, and brightness) will be treated individually. The saturation and brightness components are clamped to lie between 0 and 1, and the hue degrees are modulated by 360 to lie between 0 and 360.
Parameters
baseValue:Object — The start value of the interpolation.
| |
incrementValue:Object — The change to apply to the baseValue.
|
Object — The interpolated value.
|
interpolate | () | methode |
public function interpolate(fraction:Number, startValue:Object, endValue:Object):Object| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 4 |
| Runtimeversies: | Flash Player 10, AIR 1.5 |
The interpolation for the HSBInterpolator class takes the form of parametric calculations on each of the three values h (hue), s (saturation), and b (brightness) of HSB colors derived from the start and end RGB colors.
Parameters
fraction:Number — The fraction elapsed of the
animation, between 0.0 and 1.0.
| |
startValue:Object — The start value of the interpolation.
| |
endValue:Object — The end value of the interpolation.
|
Object — The interpolated value.
