我正在尝试使用点将多个(20 个小图像或更多)绘制到一个图片框中,但是当我这样做时,它会复制图片框每一行的顶行。我到处搜索并尝试了很多次才能做到这一点,但我不知道有人能帮我指出正确的方向吗?

我想要完成的是:

  1. 图片1 图片2 图片3 图片4 图片1
  2. 图像2 图像4 图像1 图像3 图像3
  3. 图片4 图片7 图片2 图片1 图片6
  4. 图像3 图像7 图像3 图像7 图像6

但是我得到的是:

  1. 图片1 图片2 图片3 图片4 图片1
  2. 图片1 图片2 图片3 图片4 图片1
  3. 图片1 图片2 图片3 图片4 图片1
  4. 图片1 图片2 图片3 图片4 图片1

(当然没有数字)这是我正在使用的代码

private void Form_Load(object sender, EventArgs e)
{
    Image[] Files = new Image[7]; 
    Bitmap a = new Bitmap(@"C:\icons\icon1.png");
    Files[0] = new Bitmap(a, 80, 80);
    image1 = Files[0];
    Bitmap b = new Bitmap(@"C:\icons\icon2.png");
    Files[1] = new Bitmap(b, 80, 80);
    image2 = Files[1];
    Bitmap c = new Bitmap(@"C:\icons\icon3.png");
    Files[2] = new Bitmap(c, 80, 80);
    image3 = Files[2];
    Bitmap d = new Bitmap(@"C:\icons\icon4.png");
    Files[3] = new Bitmap(d, 80, 80);
    image4 = Files[3];
    Bitmap h = new Bitmap(@"C:\icons\icon5.png");
    Files[4] = new Bitmap(h, 80, 80);
    image5 = Files[4];
    Bitmap f = new Bitmap(@"C:\icons\icon6.png");
    Files[5] = new Bitmap(f, 80, 80);
    image6 = Files[5];
    Bitmap g = new Bitmap(@"C:\icons\icon7.png");
    Files[6] = new Bitmap(g, 80, 80);
    image7 = Files[6];

    pictureBox1.BackgroundImage = CombineBitmap(Files);
}

public static System.Drawing.Bitmap CombineBitmap(Image[] files)
    {
        List<System.Drawing.Bitmap> images = new List<System.Drawing.Bitmap>();
        System.Drawing.Bitmap finalImage = null;

        try
        {
            int width = 0;
            int height = 0;

            foreach (Image image in files)
            {
                System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(image);

                width += bitmap.Width;
                height = bitmap.Height > height ? bitmap.Height : height;

                images.Add(bitmap);
            }

            finalImage = new System.Drawing.Bitmap(width, height);

            using (System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(finalImage))
            {
                g.Clear(System.Drawing.Color.Gray); // Change this to whatever you want the background color to be, you may set this to Color.Transparent as well

                int offset = 15;
                Point p1 = new Point(0, 0);
                Point p2 = new Point(80, 0);

您的finalImage位图尺寸太小,只允许单行图像。然后,PictureBox 控件平铺单行图像,为您提供所看到的图像。

您正在绘制 80 像素宽 x 80 像素高的块中的图像。因此,位图应该足够宽以容纳80 * numColumns像素,并且足够高以容纳80 * numRows像素。

由于您有 5 列和 4 行,请使用以下命令:

finalImage = new System.Drawing.Bitmap(400, 320);
