Sample Visual Basic Procedure
Sub savegraphic

' Set desired_slide equal to the slide number to be exported. Const desired_slide As Long = 1

' Set path equal to the desired file storage location. Const path As String = "c:"

' Set filename equal to the desired name of the graphic file. Const filename As String = "slide" & desired_slide

' Set graphic_type equal to three letter ' extension for your graphic type. Const graphic_type As String = "png"

' Set scalewidth equal to horizontal ' width in pixels where 96 pixels = 1 inch. ' This parameter applies to PNG, GIF & JPG, but not WMF Const scalewidth As Long = 240

' Set scaleheight equal to vertical ' height in pixels where 96 pixels = 1 inch. ' This parameter applies to PNG, GIF & JPG, but not WMF Const scaleheight As Long = 192

' Exports the desired slide as a graphic. With Application.ActivePresentation.Slides(desired_slide) .Export path & "\" & filename, graphic_type, scalewidth, _ scaleheight End With

MsgBox "you have successfully exported slide" & desired_slide _ & " to" & Chr(13) & path & "\" & filename & "." _        & graphic_type, _ vbInformation, "Export Result"

End Sub

Graphic Formats Supported
The .export command supports BMP, TIF, WMF, JPG, GIF, and PNG.

Graphic Formats Not Supported
The following file formats are NOT supported by the .export command: CDR, CGM, DRW, EMF, EPS, PCD, PCX, PCT, and WPG

Optional Parameters for Scaling the Graphic
ScaleWidth and ScaleHeight are optional parameters that are valid for the BMP, PNG, GIF, and JPG file formats, but are ignored when you export to the WMF file format. The value you enter for these two parameters is the number of pixels desired for width and height. The PNG, GIF, and JPG graphics export at a rate of 96 pixels per inch. Since these two parameters are Longs, only integer values are valid. Any numbers to the right of the decimal point is ignored. An entry of 1 or less is also ignored.

No Save Over Protection
This macro does not warn against overwriting files with the same name. When you save a graphic to a folder that contains a graphic with the same name, the original graphic is overwritten by the new graphic.
