Export pictures from excel file into jpg using VBA - image

Question

I have an Excel file which includes pictures in column B and I want like to export them into several files as .jpg (or any other picture file format). The name of the file should be generated from text in column A. I tried following VBA macro:
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
The result is that it generates files (jpg), without any content. I assume the line Print #1, cell.Offset(0, 1).text. is wrong.
I don't know what I need to change it into, cell.Offset(0, 1).pix?
Can anybody help me? Thanks!

If i remember correctly, you need to use the "Shapes" property of your sheet.
Each Shape object has a TopLeftCell and BottomRightCell attributes that tell you the position of the image.
Here's a piece of code i used a while ago, roughly adapted to your needs. I don't remember the specifics about all those ChartObjects and whatnot, but here it is:
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

This code:
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
was copied directly from here, and works beautifully for the cases I tested.

''' Set Range you want to export to the folder
Workbooks("your workbook name").Sheets("yoursheet name").Select
Dim rgExp As Range: Set rgExp = Range("A1:H31")
''' Copy range as picture onto Clipboard
rgExp.CopyPicture Appearance:=xlScreen, Format:=xlBitmap
''' Create an empty chart with exact size of range copied
With ActiveSheet.ChartObjects.Add(Left:=rgExp.Left, Top:=rgExp.Top, _
Width:=rgExp.Width, Height:=rgExp.Height)
.Name = "ChartVolumeMetricsDevEXPORT"
.Activate
End With
''' Paste into chart area, export to file, delete chart.
ActiveChart.Paste
ActiveSheet.ChartObjects("ChartVolumeMetricsDevEXPORT").Chart.Export "C:\ExportmyChart.jpg"
ActiveSheet.ChartObjects("ChartVolumeMetricsDevEXPORT").Delete

Answer 4

Dim filepath as string
Sheets("Sheet 1").ChartObjects("Chart 1").Chart.Export filepath & "Name.jpg"
Slimmed down the code to the absolute minimum if needed.

New versions of excel have made old answers obsolete. It took a long time to make this, but it does a pretty good job. Note that the maximum image size is limited and the aspect ratio is ever so slightly off, as I was not able to perfectly optimize the reshaping math. Note that I've named one of my worksheets wsTMP, you can replace it with Sheet1 or the like. Takes about 1 second to print the screenshot to target path.
Option Explicit
Private Declare PtrSafe Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
Sub weGucciFam()
Dim tmp As Variant, str As String, h As Double, w As Double
Application.PrintCommunication = False
Application.EnableEvents = False
Application.Calculation = xlCalculationManual
Application.ScreenUpdating = False
If Application.StatusBar = False Then Application.StatusBar = "EVENTS DISABLED"
keybd_event vbKeyMenu, 0, 0, 0 'these do just active window
keybd_event vbKeySnapshot, 0, 0, 0
keybd_event vbKeySnapshot, 0, 2, 0
keybd_event vbKeyMenu, 0, 2, 0 'sendkeys alt+printscreen doesn't work
wsTMP.Paste
DoEvents
Const dw As Double = 1186.56
Const dh As Double = 755.28
str = "C:\Users\YOURUSERNAMEHERE\Desktop\Screenshot.jpeg"
w = wsTMP.Shapes(1).Width
h = wsTMP.Shapes(1).Height
Application.DisplayAlerts = False
Set tmp = Charts.Add
On Error Resume Next
With tmp
.PageSetup.PaperSize = xlPaper11x17
.PageSetup.TopMargin = IIf(w > dw, dh - dw * h / w, dh - h) + 28
.PageSetup.BottomMargin = 0
.PageSetup.RightMargin = IIf(h > dh, dw - dh * w / h, dw - w) + 36
.PageSetup.LeftMargin = 0
.PageSetup.HeaderMargin = 0
.PageSetup.FooterMargin = 0
.SeriesCollection(1).Delete
DoEvents
.Paste
DoEvents
.Export Filename:=str, Filtername:="jpeg"
.Delete
End With
On Error GoTo 0
Do Until wsTMP.Shapes.Count < 1
wsTMP.Shapes(1).Delete
Loop
Application.PrintCommunication = True
Application.EnableEvents = True
Application.Calculation = xlCalculationAutomatic
Application.ScreenUpdating = True
Application.StatusBar = False
End Sub

Thanks for the ideas! I used the above ideas to make a macro to do a bulk file conversion--convert every file of one format in a folder to another format.
This code requires a sheet with cells named "FilePath" (which must end in a "\"), "StartExt" (original file extension), and "EndExt" (desired file extension). Warning: it doesn't ask for confirmation before replacing existing files with the same name and extension.
Private Sub CommandButton1_Click()
Dim path As String
Dim pathExt As String
Dim file As String
Dim oldExt As String
Dim newExt As String
Dim newFile As String
Dim shp As Picture
Dim chrt As ChartObject
Dim chrtArea As Chart
Application.ScreenUpdating = False
Application.DisplayAlerts = False
'Get settings entered by user
path = Range("FilePath")
oldExt = Range("StartExt")
pathExt = path & "*." & oldExt
newExt = Range("EndExt")
file = Dir(pathExt)
Do While Not file = "" 'cycle through all images in folder of selected format
Set shp = ActiveSheet.Pictures.Insert(path & file) 'Import image
newFile = Replace(file, "." & oldExt, "." & newExt) 'Determine new file name
Set chrt = ActiveSheet.ChartObjects.Add(0, 0, shp.Width, shp.Height) 'Create blank chart for embedding image
Set chrtArea = chrt.Chart
shp.CopyPicture 'Copy image to clipboard
With chrtArea 'Paste image to chart, then export
.ChartArea.Select
.Paste
.Export (path & newFile)
End With
chrt.Delete 'Delete chart
shp.Delete 'Delete imported image
file = Dir 'Advance to next file
Loop
Application.ScreenUpdating = True
Application.DisplayAlerts = True
End Sub

Here is another cool way to do it- using en external viewer that accepts command line switches (IrfanView in this case) :
* I based the loop on what Michal Krzych has written above.
Sub ExportPicturesToFiles()
Const saveSceenshotTo As String = "C:\temp\"
Const pictureFormat As String = ".jpg"
Dim pic As Shape
Dim sFileName As String
Dim i As Long
i = 1
For Each pic In ActiveSheet.Shapes
pic.Copy
sFileName = saveSceenshotTo & Range("A" & i).Text & pictureFormat
Call ExportPicWithIfran(sFileName)
i = i + 1
Next
End Sub
Public Sub ExportPicWithIfran(sSaveAsPath As String)
Const sIfranPath As String = "C:\Program Files\IrfanView\i_view32.exe"
Dim sRunIfran As String
sRunIfran = sIfranPath & " /clippaste /convert=" & _
sSaveAsPath & " /killmesoftly"
' Shell is no good here. If you have more than 1 pic, it will
' mess things up (pics will over run other pics, becuase Shell does
' not make vba wait for the script to finish).
' Shell sRunIfran, vbHide
' Correct way (it will now wait for the batch to finish):
call MyShell(sRunIfran )
End Sub
Edit:
Private Sub MyShell(strShell As String)
' based on:

Dim wsh As Object
Dim waitOnReturn As Boolean:
Dim windowStyle As VbAppWinStyle
Set wsh = VBA.CreateObject("WScript.Shell")
waitOnReturn = True
windowStyle = vbHide
wsh.Run strShell, windowStyle, waitOnReturn
End Sub
