如何分解整数数组为一个字节数组（像素的编码） [英] how to decompose integer array to a byte array (pixel codings)

问题描述

喜对不起，通过改写我的问题是恼人的，但我只是发现我的答案的地步。

我 INT 阵列RGB值组成的，我需要分解的 INT 数组转换成字节阵列，但应在BGR顺序

RGB值组成的整型数组被创建，像这样：

  PIX [指数++] =（255＆LT;＆LT; 24）| （红色＆LT;＆LT; 16）|蓝色;
 

解决方案

C＃code

 
        //转换成整数数组重新presenting [ARGB]值的字节数组重新presenting [BGR]值
        私人字节[] convertArray（INT []数组）
        {
            字节[] = newarray新的字节[array.Length * 3]; 

            的for（int i = 0; I＆LT; array.Length;我++）
            {

                newarray [我* 3 =（字节）阵列[我]
                newarray [我* 3 + 1] =（字节）（数组[我] >> 8）;
                newarray [I * 3 + 2] =（字节）（数组[I] >> 16）; 

            }
            返回newarray;
        }

Hi sorry for being annoying by rephrasing my question but I am just on the point of discovering my answer.

I have an array of int composed of RGB values, I need to decompose that int array into a byte array, but it should be in BGR order.

The array of int composed of RGB values is being created like so:

pix[index++] = (255 << 24) | (red << 16) | blue;

解决方案

C# code

        // convert integer array representing [argb] values to byte array representing [bgr] values
        private byte[] convertArray(int[] array)
        {
            byte[] newarray = new byte[array.Length * 3];

            for (int i = 0; i < array.Length; i++)
            {

                newarray[i * 3] = (byte)array[i];
                newarray[i * 3 + 1] = (byte)(array[i] >> 8);
                newarray[i * 3 + 2] = (byte)(array[i] >> 16);

            }
            return newarray;
        }
