使用VBA和ImageMagick旋转文件夹中的选定图像

我想检查一个文件夹,如果存在我的图像的旋转版本,如果不存在,我想使用ImageMagick为我自动执行该操作(如果是更好的选择,可以使用其他程序)。这是我的代码:

Dim imageDomain As String
Dim imagePath As String
Dim rotatePath As String
Dim rotateBool As Boolean
Dim imageRotator As Integer
Dim rs As DAO.Recordset
Set rs = CurrentDb.OpenRecordset("SELECT Afbeelding FROM Products")

imageDomain = CurrentProject.Path & "\folder\"

If Not (rs.EOF And rs.BOF) Then
    rs.MoveFirst
    Do Until rs.EOF = True

        If Not IsNull(rs!Afbeelding) Then
            rotatePath = imageDomain & "rotate\" & rs!Afbeelding
            rotateBool = Len(Dir(rotatePath))

            If Not rotateBool Then
                imagePath = imageDomain & rs!Afbeelding
                imageRotator = Shell("cmd.exe /c convert.exe -rotate ""270"" " & imagePath & " " & rotatePath)
            End If
        End If

        rs.MoveNext
    Loop
Else
    MsgBox "There are no records in the recordset."
End If

rs.Close
Set rs = Nothing

代码在shell命令中给出了一个溢出错误。如何使用VBA通过ImageMagick有选择地旋转所需的图像?使用批处理文件是否会旋转文件夹中的所有图像?
