ArgbEvaluator
extends Object
implements
TypeEvaluator
This evaluator can be used to perform type interpolation between integer
values that represent ARGB colors.

evaluate(float fraction, T startValue, T endValue)
This function returns the result of linearly interpolating the start and end values, with
fraction representing the proportion between the start and end values.

evaluate
Object evaluate (float fraction,
Object startValue,
Object endValue)
This function returns the calculated in-between value for a color
given integers that represent the start and end values in the four
bytes of the 32-bit int. Each channel is separately linearly interpolated
and the resulting calculated values are recombined into the return value.
| Parameters |
|---|
fraction |
float:
The fraction from the starting to the ending values |
startValue |
Object:
A 32-bit int value representing colors in the
separate bytes of the parameter |
endValue |
Object:
A 32-bit int value representing colors in the
separate bytes of the parameter |
| Returns |
|---|
Object |
A value that is calculated to be the linearly interpolated
result, derived by separating the start and end values into separate
color channels and interpolating each one separately, recombining the
resulting values in the same way.
