我有一个 Windows 窗体应用程序，它在执行时会启动 Firefox，获取窗口的进程和句柄，并对 Firefox 进行屏幕截图，将其保存到磁盘 (temp.bmp) 并调用 ProcessGetWindow。我基本上是在 MODI 中使用 MiSelectRects 来捕获我正在寻找的单词周围的矩形，然后我使用 AutoIT 鼠标单击单词。

问题是我的坐标离顶部大约 10 个像素。

有什么想法可能是错的吗？这是进行处理的函数。我已经注释掉了 AutoIT 处理，我只是在使用 MessageBox 进行调试以显示实际坐标。然后我用 AutoIT 的 Window Info 工具确认它肯定是关闭的......我做错了什么还是 MODI 搞砸了？

public void ProcessGetWindow(Bitmap image)
        {           
            Document modiDoc = null;
            MiDocSearch modiSearch = null;
            IMiSelectableItem modiTextSel = null;
            MiSelectRects modiSelectRects = null;
            MiSelectRect modiSelectRect = null;
            MiRects modiRects = null;
            int intSelInfoPN;
            string intSelInfoTop;
            int intSelInfoBottom;
            string intSelInfoLeft;
            int intSelInfoRight;            

            // Load an existing image file.
            modiDoc = new Document();
            modiDoc.Create(@"C:\\temp.bmp");

            // Perform OCR.
            modiDoc.Images[0].OCR();

            // Search for the selected word.
            modiSearch = new MiDocSearch();
            modiSearch.Initialize(modiDoc, "Click Me", 0, 0, false, false);
            modiSearch.Search(null, ref modiTextSel);       

            try
            {          
                modiSelectRects = modiTextSel.GetSelectRects();
            }
            catch (COMException)
            {
                MessageBox.Show("Me thinks that the OCR didn't work right!");
            }

            foreach (MiSelectRect mr in modiSelectRects)
            {
                //intSelInfoPN = mr.PageNumber.ToString();
                intSelInfoTop = mr.Top.ToString();
                //intSelInfoBottom = mr.Bottom;
                intSelInfoLeft = mr.Left.ToString();
                //intSelInfoRight = mr.Right;

                /*AutoItX3 auto = new AutoItX3();
                auto.AutoItSetOption("MouseCoordMode", 2);
                auto.MouseClick("", intSelInfoLeft, intSelInfoTop, 1, 80);*/

                MessageBox.Show("Coordinates: " + intSelInfoLeft + ", " + intSelInfoTop, "Coordinates", MessageBoxButtons.OK);            
            }

            //string textResult = modiTextSel.Text;

            //MessageBox.Show(textResult, "Search Results", MessageBoxButtons.OK);

            // Close this dialog.
            Application.Exit();
        }

我正在使用相同的程序来查找位置。

int centerwidth = (intSelInfoRight - intSelInfoLeft)/2;
                centerwidth = intSelInfoLeft + centerwidth;
                 int centerheight = (intSelInfoBottom - intSelInfoTop)/2;
                 centerheight = centerheight + intSelInfoTop;

您可以使用它找到文本的确切中间点。

但是这个程序总是给出单词第一次出现的位置，而不是下一次出现的位置。请让我知道如何在所有出现的地方找到文本的位置。

我不熟悉提供的工具，但从我读到的GetSelectRects函数返回一个边界矩形，这是包含整个选择的最小矩形，在这种情况下是您搜索的单词。我相信会发生什么是您单击边界矩形的角而不是单词所在的中间。

计算矩形中心的坐标并尝试单击：

int height = mr.Bottom - mr.Top;
int width = mr.Right - mr.Left;

AutoItX3 auto = new AutoItX3();
auto.AutoItSetOption("MouseCoordMode", 2);
auto.MouseClick("", width/2, height/2, 1, 80);
