lerpColor()线性颜色

Name

lerpColor()线性颜色

Examples

stroke(255);

background(51);

color from = color(204, 102, 0);

color to = color(0, 102, 153);

color interA = lerpColor(from, to, .33);

color interB = lerpColor(from, to, .66);

fill(from);

rect(10, 20, 20, 60);

fill(interA);

rect(30, 20, 20, 60);

fill(interB);

rect(50, 20, 20, 60);

fill(to);

rect(70, 20, 20, 60);

Description

Calculates a color or colors between two color at a specific increment. The amt parameter is the amount to interpolate between the two values where 0.0 equal to the first point, 0.1 is very near the first point, 0.5 is halfway in between, etc. 
An amount below 0 will be treated as 0. Likewise, amounts above 1 will be capped at 1. This is different from the behavior of lerp(), but necessary because otherwise numbers outside the range will produce strange and unexpected colors.

在特定增量中计算两种颜色之间的颜色或颜色。amt 参数是在两个值之间插补的量, 其中0.0 等于第一个点, 0.1 是非常接近第一点, 0.5 是介于中间, 等等。

低于0的金额将被视为0。同样, 1 以上的金额将封顶1。这与 lerp () 的行为不同, 但有必要, 因为在范围之外的数字会产生奇怪的和意想不到的颜色。
