如何在 C# 中将 .bmp 文件转换为 1 和 0 的数组?

How can I convert a .bmp file into an array of 1s and 0s in C#?

我有一个简单的黑白 .bmp 文件,我想通过 C# 将其转换为一系列 0 和 1,不包括文件 header 和填充。 图像是 32x32 像素,这是我迄今为止尝试过的,但我无法删除填充和 header 信息。

public BitArray imageToBinaryArray(System.Drawing.Image imageIn)
{
    MemoryStream ms = new MemoryStream();
    bool[] arr = new bool[50000000];
    int i = 0;
    imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp);
    BitArray bitarray = new BitArray(ms.ToArray());
    return bitarray;
}

private void readImage()
{
    BitArray data;
    string path = @"C:\Users\me\dummy.bmp";
    Image Dummy = Image.FromFile(path);
    data = imageToBinaryArray(Dummy);

    var sb = new StringBuilder();

    for (int i = 0; i < data.Count; i++)
    {
        char c = data[i] ? '1' : '0';
        sb.Append(c);
    }
    string s = sb.ToString();
    Console.WriteLine(s);
}

你可以看到下面我要翻译的图

这是我要打印的内容:

在此先感谢所有愿意帮助我的人!

如解释的那样here, you can read the image into a Bitmap。然后遍历像素并将它们写入您的文本文件。

using System.Drawing;

Bitmap img = new Bitmap("*imagePath*");
for (int i = 0; i < img.Width; i++)
{
    for (int j = 0; j < img.Height; j++)
    {
        Color pixel = img.GetPixel(i,j);

        if (pixel == *somecondition*)
        {
            **Store pixel here in a array or list or whatever** 
        }
    }
} 

尝试以下操作:

            byte[] input = {0x00, 0x00, 0x00, 0x00,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0x55, 0x55, 0x55, 0x55,
                            0xAA, 0xAA, 0xAA, 0xAA,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0x00, 0x00, 0x00, 0x00,
                            0x00, 0x00, 0x00, 0x01,
                            0x00, 0x00, 0x00, 0x03,
                            0x00, 0x00, 0x00, 0x0F,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0xF0, 0x00, 0x00, 0x00,
                            0xE0, 0x00, 0x00, 0x00,
                            0xC0, 0x00, 0x00, 0x00,
                            0x80, 0x00, 0x00, 0x00,
                            0x00, 0x00, 0x00, 0x00,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0xFF, 0xFF, 0xFF, 0xFF,
                            0xFF, 0xFF, 0xFF, 0xFF
                           };
            string[] doubleWords = input.Select((x,i) => new {b = x, index = i})
                .GroupBy(x => x.index/4)
                .Select(x => string.Join("",x.Select(y => Convert.ToString(y.b, 2).PadLeft(8,'0'))))
                .ToArray();
