Question

任何人都能够帮助部分逐渐改变肤色。我只想改变颜色。

new Color(255,0,0)

页: 1

new Color(0,0,0)

尝试不同的变体时器,但 st。而与时间者一道这样做是正确的吗?

提前感谢!

Answer 1

请考虑将J Layer作为你寻求的备选办法:-

Answer 2

大致如下:

Color before = new Color(255,0,0);
Color after = new Color(0,0,0);
Color current = before;
int maxtime = 1000;
int step = 0;

public void step()
{
    if(step == maxtime)
        return;
    step++;
    double percentComplete = step/maxtime;
    double percentGone = 1-percentComplete;
    int red = (int)(before.getRed()*percentGone+after.getRed()*percentComplete);
    int green = (int)(before.getGreen()*percentGone+after.getGreen()*percentComplete);
    int blue = (int)(before.getBlue()*percentGone+after.getBlue()*percentComplete);
    int alpha = (int)(before.getAlpha()*percentGone+after.getAlpha()*percentComplete);
    current = new Color(red, green, blue, alpha);
    //set component s color to current
}

值得注意的是,你可能需要做一些检查,以确保红色绿色和蓝色不会超过255,但我还不清楚。

(这一职能应当属于你重新改变的颜色部分,你应当按每个时间尺度来说明这一点)
