I am trying to extract text from a .pptx file. I am able to extract from all other shapes except a shape that is identified as a msoPicture to right click on this shape in powerpoint and ungroup it, but when I try to do this from code it tell me that the ungroup method only applied to group shapes.I did some research and found out that the msopicture shape comes from a .emf file but I don't have the least idea how to ungroup this shape or get the text from it through code.NB: When I right click on the shape in powerpoint and select ungroup a message box pops up saying "This is an imported picture, not a group. Do you want to convert it to a Microsoft Office drawing object?". But I cannot seem to find a way in code to convert this shape to Ms Office drawing object.
