$image = @MyDocumentsDir & "\aaa_teste.jpg"

Func OCR($Image)

    If $Error = False Then
        $i = 0
        For $oWord in $miDoc.Images(0).Layout.Words

            $str = $str & $oWord.text & @CrLf
                ConsoleWrite($oWord.text & @CRLF)
            $sArray [$i] = $oWord.text
            $i += 1

        Next

        $as_Text = _ArrayToString($sArray," ",0)
        $as_Text = StringReplace($as_Text, "  ", "", 0)

    ElseIf $Error = True Then

        $Error = False
    EndIf

    $miDoc.Close(False)
    Return $as_Text

EndFunc

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

请帮帮我

MODI 库的唯一缺点是它 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。

检查你安装的 Office 版本，看看里面是否有 MODI。 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 安装它们后，转到>卸载程序>MS Office SharePoint Designer 2007>右键单击它并选择更改>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。 然后点击 MODI(Microsoft Office Document Imaging) 上的小箭头并选择“从我的电脑运行所有内容”。

你准备好了！
