How to align powerpoint texts and images using matlab activex commands

I am trying to automate the process of presenting Matlab graphs in powerpoint. I have figured out how to create a presentation and add slides, pictures, and texts to the presentation; however, I have not found a way to align the texts or images within the slides.

Is there a code to do this?

I have tried using the following without success:

Title1.Text.Frame.TextRange.ParagraphFormat.Alignment = 'ppAlignCenter'; Title1.Text.Frame.TextRange.ParagraphFormat.Alignment = ppAlignCenter; SlideImage1.PictureAlignment = 2;

Here is the code I have right now: % Open PowerPoint as a COM Automation server ppt = actxserver('PowerPoint.Application'); % Show the PowerPoint window ppt.Visible = 1; % Bring up the PowerPoint session help window - this contains the API, the % complete function list. At first it's a little intimidating, but after % acclimating it's not hard to find the methods you're looking for. Also, % the function signatures are given in VBA syntax, so they takes a little % deciphering. ppt.Help; % ADD PRESENTATION % View the methods that can be invoked ppt.Presentation.invoke; % Add a presentation via "Add" method Presentation = ppt.Presentation.Add; % ADD SLIDES % View the methods that can be invoked Presentation.Slides.invoke; % Add a slide via "Add" method blankSlide = Presentation.SlideMaster.CustomLayouts.Item(1); Slide1 = Presentation.Slides.AddSlide(1,blankSlide); SlideImage1 = Slide1.Shapes.AddPicture(ImageDirectory1,'msoFalse','msoTrue',0,0,300,300); SlideTitle1 = Slide1.Shapes.AddTextbox('msoTextOrientationHorizontal',0,0,400,70); SlideTitle1.TextFrame.TextRange.Text = Title1; SlideTitle1.TextFrame.TextRange.ParagraghFormat.Alignment = ppAlignCenter; Slide2 = Presentation.Slides.AddSlide(2,blankSlide); SlideImage2 = Slide2.Shapes.AddPicture(ImageDirectory2,'msoFalse','msoTrue',0,0,400,400); SlideTitle2 = Slide2.Shapes.AddTextbox('msoTextOrientationHorizontal',0,0,400,70); SlideTitle2.TextFrame.TextRange.Text = Title2; Slide3 = Presentation.Slides.AddSlide(3,blankSlide); Slide4 = Presentation.Slides.AddSlide(4,blankSlide); Slide5 = Presentation.Slides.AddSlide(5,blankSlide); Slide6 = Presentation.Slides.AddSlide(6,blankSlide); Slide7 = Presentation.Slides.AddSlide(7,blankSlide); Slide8 = Presentation.Slides.AddSlide(8,blankSlide); Slide9 = Presentation.Slides.AddSlide(9,blankSlide); Slide10 = Presentation.Slides.AddSlide(10,blankSlide);

PPTDirectory = strcat(Directory,'/',PowerPointPresentationTitle,'.ppt'); Presentation.SaveAs(PPTDirectory);

Any help would be greatly appreciated!
