我正在尝试从屏幕截图中读取文本错误是：

"C:\Users\jose.barbosaneto\Desktop\TESTE.au3" (23) : ==> 变量必须是“对象”类型。: $miDoc.Create(@TempDir & '\OCR_ImageResize.jpg') $miDoc ^ 错误

请帮我

MODI 库唯一的缺点是它 100% 依赖于 MS Office。因此，如果您没有安装正确的版本，它将找不到所需的 COM 对象。

检查您已安装的 Office 版本，并查看 MODI 是否在其中。进入卸载程序并单击您拥有的 MS Office 版本上的更改/修复。从那里您可以检查是否安装了 MODI 文档。

编辑：从此链接安装 MDI 到 TIFF 文件转换器和 SharePoint Designer：https: //support.microsoft.com/en-us/kb/982760 安装后转到>卸载程序>MS Office SharePoint Designer 2007>右键单击在其上并选择更改>选择添加或删除功能。从那里的菜单中，您将找到选项 Office 工具。展开它。然后单击 MODI（Microsoft Office Document Imaging）上的小箭头并选择“从我的计算机运行所有内容”。

你准备好了！
