使用VBA将excel文件中的图片导出为jpg

Question

我有一个Excel文件,其中包含B列中的图片,我想将它们导出为.jpg(或任何其他图片文件格式)的几个文件.应该从A列中的文本生成文件的名称.我尝试遵循VBA宏:

Private Sub CommandButton1_Click()
Dim oTxt As Object
 For Each cell In Ark1.Range("A1:A" & Ark1.UsedRange.Rows.Count)
 ' you can change the sheet1 to your own choice
 saveText = cell.Text
 Open "H:\Webshop_Zpider\Strukturbildene\" & saveText & ".jpg" For Output As #1
 Print #1, cell.Offset(0, 1).text
 Close #1
 Next cell
End Sub

结果是它生成文件(jpg),没有任何内容.我认为这条线Print #1, cell.Offset(0, 1).text.是错的.我不知道我需要改变它,cell.Offset(0, 1).pix？

有谁能够帮我？谢谢!

这段代码:

Option Explicit

Sub ExportMyPicture()

     Dim MyChart As String, MyPicture As String
     Dim PicWidth As Long, PicHeight As Long

     Application.ScreenUpdating = False
     On Error GoTo Finish

     MyPicture = Selection.Name
     With Selection
           PicHeight = .ShapeRange.Height
           PicWidth = .ShapeRange.Width
     End With

     Charts.Add
     ActiveChart.Location Where:=xlLocationAsObject, Name:="Sheet1"
     Selection.Border.LineStyle = 0
     MyChart = Selection.Name & " " & Split(ActiveChart.Name, " ")(2)

     With ActiveSheet
           With .Shapes(MyChart)
                 .Width = PicWidth
                 .Height = PicHeight
           End With

           .Shapes(MyPicture).Copy

           With ActiveChart
                 .ChartArea.Select
                 .Paste
           End With

           .ChartObjects(1).Chart.Export Filename:="MyPic.jpg", FilterName:="jpg"
           .Shapes(MyChart).Cut
     End With

     Application.ScreenUpdating = True
     Exit Sub

Finish:
     MsgBox "You must select a picture"
End Sub

直接从这里复制,并为我测试的案例工作得很漂亮.

如果我没记错的话,您需要使用工作表的"形状"属性.

每个Shape对象都有一个TopLeftCell和BottomRightCell属性,可以告诉您图像的位置.

这是我前一段时间使用的一段代码,大致适合您的需求.我不记得有关所有ChartObjects和whatnot的具体细节,但这里是:

For Each oShape In ActiveSheet.Shapes
    strImageName = ActiveSheet.Cells(oShape.TopLeftCell.Row, 1).Value
    oShape.Select
    'Picture format initialization
    Selection.ShapeRange.PictureFormat.Contrast = 0.5: Selection.ShapeRange.PictureFormat.Brightness = 0.5: Selection.ShapeRange.PictureFormat.ColorType = msoPictureAutomatic: Selection.ShapeRange.PictureFormat.TransparentBackground = msoFalse: Selection.ShapeRange.Fill.Visible = msoFalse: Selection.ShapeRange.Line.Visible = msoFalse: Selection.ShapeRange.Rotation = 0#: Selection.ShapeRange.PictureFormat.CropLeft = 0#: Selection.ShapeRange.PictureFormat.CropRight = 0#: Selection.ShapeRange.PictureFormat.CropTop = 0#: Selection.ShapeRange.PictureFormat.CropBottom = 0#: Selection.ShapeRange.ScaleHeight 1#, msoTrue, msoScaleFromTopLeft: Selection.ShapeRange.ScaleWidth 1#, msoTrue, msoScaleFromTopLeft
    '/Picture format initialization
    Application.Selection.CopyPicture
    Set oDia = ActiveSheet.ChartObjects.Add(0, 0, oShape.Width, oShape.Height)
    Set oChartArea = oDia.Chart
    oDia.Activate
    With oChartArea
        .ChartArea.Select
        .Paste
        .Export ("H:\Webshop_Zpider\Strukturbildene\" & strImageName & ".jpg")
    End With
    oDia.Delete 'oChartArea.Delete
Next
