The biggest compatibility problem for me in Libreoffice writer is export of charts, formulas and other objects, when saving documents in Microsoft word copatible formats like doc or docx. The objects are not visible in word or they are destroyed, or thay cannot be copied to other word documents, even if they are visible (because libreoffice or openoffice.org is installed on host machine).

Conversion of every single chart into picture is time consuming, therefore macro command, that can do it at once (batch conversion) would be very welcome.

There is simple macro for word to convert all objects into pictures. Probably it can be converted into Libreoffice macro code to do the same job:

Sub ConvertOLEObjectsToPicture()
  Dim Item As InlineShape
  For Each Item In ActiveDocument.InlineShapes
    Select Case Item.Type
      Case wdInlineShapeEmbeddedOLEObject, wdInlineShapeLinkedOLEObject
        Item.Select
        With Selection
          .CopyAsPicture
          .Delete
          .PasteSpecial DataType:=wdPasteMetafilePicture
          '.ShapeRange.WrapFormat.Type = wdWrapTopBottom
        End With
    End Select
  Next
End Sub

Bad thing in this macro is that it do not follows to original anchoring rules, so anyway all converted objects should be anchored separately.

It would be reasonable to have this macro separately, probably as extension, to be able to use in in openoffice 2.4, because all libre and open office versions after 3 has fatal regression in exporting complex tables, therefore 2.4 has to be used to export documents to word compatible format.
