ArgbEvaluator


class ArgbEvaluator : TypeEvaluator


This evaluator can be used to perform type interpolation between integer values that represent ARGB colors.

Summary

Public functions

Int
evaluate(fraction: Float, startValue: Int, endValue: Int)

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.

java-static ArgbEvaluator

Returns an instance of ArgbEvaluator that may be used in setEvaluator.

Public functions

evaluate

fun evaluate(fraction: Float, startValue: Int, endValue: Int): Int

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: Int

A 32-bit int value representing colors in the separate bytes of the parameter

endValue: Int

A 32-bit int value representing colors in the separate bytes of the parameter

Returns
Int

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.

getInstance

java-static fun getInstance(): ArgbEvaluator

Returns an instance of ArgbEvaluator that may be used in setEvaluator. The same instance may be used in multiple Animators because it holds no state.

Returns
ArgbEvaluator

An instance of ArgbEvaluator.
