c# - 如何在屏幕上找到图像并获取鼠标坐标？

Question

我想在屏幕上找到图像并获取 x,y 坐标（如果它在屏幕上匹配）。我已经知道如何使用这个 x,y 坐标移动鼠标并单击。

EG：我想给出图标图像，代码将获取桌面截图并找到图像，移动鼠标。

以下代码有效，但如果我更改屏幕分辨率，我必须再次获取图像（bmpMatch）。

    private static Rectangle FindImageOnScreen(Bitmap bmpMatch, bool ExactMatch)
    {
        Rectangle rct = Rectangle.Empty;
        try
        {
            Bitmap ScreenBmp = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
            Graphics g = Graphics.FromImage(ScreenBmp);
            g.CopyFromScreen(Screen.PrimaryScreen.Bounds.X,
                    Screen.PrimaryScreen.Bounds.Y,
                        0, 0,
                        ScreenBmp.Size,
                        CopyPixelOperation.SourceCopy);


            BitmapData ImgBmd = bmpMatch.LockBits(new Rectangle(0, 0, bmpMatch.Width, bmpMatch.Height), ImageLockMode.ReadOnly, PixelFormat.Format24bppRgb);
            BitmapData ScreenBmd = ScreenBmp.LockBits(new Rectangle(0, 0, ScreenBmp.Width, ScreenBmp.Height), ImageLockMode.ReadOnly, PixelFormat.Format24bppRgb);

            byte[] ImgByts = new byte[(Math.Abs(ImgBmd.Stride) * bmpMatch.Height) - 1 + 1];
            byte[] ScreenByts = new byte[(Math.Abs(ScreenBmd.Stride) * ScreenBmp.Height) - 1 + 1];

            Marshal.Copy(ImgBmd.Scan0, ImgByts, 0, ImgByts.Length);
            Marshal.Copy(ScreenBmd.Scan0, ScreenByts, 0, ScreenByts.Length);

            bool FoundMatch = false;
            
            int sindx, iindx;
            int spc, ipc;

            int skpx = System.Convert.ToInt32((bmpMatch.Width - 1) / (double)10);
            if (skpx < 1 | ExactMatch)
                skpx = 1;
            int skpy = System.Convert.ToInt32((bmpMatch.Height - 1) / (double)10);
            if (skpy < 1 | ExactMatch)
                skpy = 1;

            for (int si = 0; si <= ScreenByts.Length - 1; si += 3)
            {
                FoundMatch = true;
                for (int iy = 0; iy <= ImgBmd.Height - 1; iy += skpy)
                {
                    for (int ix = 0; ix <= ImgBmd.Width - 1; ix += skpx)
                    {
                        sindx = (iy * ScreenBmd.Stride) + (ix * 3) + si;
                        iindx = (iy * ImgBmd.Stride) + (ix * 3);
                        spc = Color.FromArgb(ScreenByts[sindx + 2], ScreenByts[sindx + 1], ScreenByts[sindx]).ToArgb();
                        ipc = Color.FromArgb(ImgByts[iindx + 2], ImgByts[iindx + 1], ImgByts[iindx]).ToArgb();
                        if (spc != ipc)
                        {
                            FoundMatch = false;
                            iy = ImgBmd.Height - 1;
                            ix = ImgBmd.Width - 1;
                        }
                    }
                }
                if (FoundMatch)
                {
                    double r = si / (double)(ScreenBmp.Width * 3);
                    double c = ScreenBmp.Width * (r % 1);
                    if (r % 1 >= 0.5)
                        r -= 1;
                    rct.X = System.Convert.ToInt32(c);
                    rct.Y = System.Convert.ToInt32(r);
                    rct.Width = bmpMatch.Width;
                    rct.Height = bmpMatch.Height;
                    break;
                }
            }

            bmpMatch.UnlockBits(ImgBmd);
            ScreenBmp.UnlockBits(ScreenBmd);
            //ScreenBmp.Dispose();
            return rct;

        } catch(Exception ex)
        {
           
            Console.Write(ex.Message);
        }
        return rct;

    }

无论如何我可以提供任何尺寸的图像，并从桌面屏幕截图中搜索它。
