Paste a figure to powerpoint with actxserver when the presentation is invisible

Hi,

I am using actxserver('PowerPoint.Application') to make PowerPoint presentations in Matlab. I changed the Open function to make the presentation invisible:

h = actxserver('PowerPoint.Application'); %Create an ActiveX object
hInterface = h.Presentation.Open( fullfile(obj.templatePath_1, obj.templateName_1), 0,0,0 ); %Open an existing presentation by supplying the fullpath to the file

To copy figures I use the following method:

function addFigure(obj, actserverPP_in, presentationInterface_in)
    %Function to copy the figure of the object to the their figure
    %placeholder

    if exist( fullfile(obj.figurePath_1, obj.figureName_1), 'file') == 2 %Check if figure exists
        openfig( fullfile(obj.figurePath_1, obj.figureName_1), 'invisible');
        
        print -clipboard -dmeta

        noLastSlide = presentationInterface_in.Slides.Count; %Get index of last slide
        Slide = presentationInterface_in.Slides.Item(noLastSlide); %Last slide
        %Slide.Select; %Select last slide -> not allowed when presentation is invisible

        Slide.Shapes.Placeholders.Item( obj.itemId_1 ).Select; %Select item to copy to
        actserverPP_in.ActiveWindow.View.Paste
        close %Close figure
    end
end

While the presentation was visible, I was able to select the slide and the placeholder item to copy the figure to. Now selecting the placeholder and paste the figure does not work anymore. I am looking for something like set(Slide.Shapes.Placeholders.Item( obj.itemId_1 ), 'Figure', fig_handle)

Any suggestions? Thanks a lot!
