使用VBA和ImageMagick旋转文件夹中的选定图像 [英] Rotate selected images in a folder using VBA and ImageMagick

问题描述

我想检查文件夹中是否存在我图像的旋转版本，如果不存在，我想使用ImageMagick为我自动执行此操作(或其他程序，如果这样会更好).这是我的代码:

I want to check a folder if a rotated version of my images exists, if it doesn't I want to use ImageMagick to automatically do it for me (or another program if it would be a better option). This is my code:

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

该代码在shell命令中给出了溢出错误.如何使用VBA使用ImageMagick选择性旋转所需的图像?使用批处理文件会旋转文件夹中的所有图像吗?

The code gives an overflow error at the shell command. How can I selectively rotate the images I want with ImageMagick using VBA? Using a batch file would rotate all images in the folder?

推荐答案

COM +对象可以解决问题.

The COM+ object did the trick.

Dim img As Object
Set img = CreateObject("ImageMagickObject.MagickImage.1")

在循环中:

imageRotator = img.Convert(imagePath, "-rotate", "270", rotatePath)
