Question

Do you know if it's possible to convert an object :Color to an array of double containing its R, its G and its B, in one line ?

It would be very practical for me because I wrote a photo-retouching function which has to be independent of the implementation's constraints (example : the language used). So this function needs a double[] as parameter and not a :Color.

For the moment, the function has three double as parameters but it's less practical.

PS : I don't want to just create myself a double[] and fill it with getRed, etc. : I really want to create and fill this array in one instruction.

Answer 1

PS：我不想创建一个双[]并填写它 getRed等：我真的想在一个中创建并填充这个数组指令。

因为这是一项非常简单的任务，是什么阻止你编写自己的方法呢？示例实现：

private double[] getColors(Color c) {
   return new double[]{c.getRed(), c.getGreen(), c.getBlue()};
}

用法：

Color c = Color.RED;
System.out.println(Arrays.toString(getColors(c)));

结果：

[1.0,0.0,0.0]
