Powerpoint Generation

[ddorsey]

I am creating a powerpoint and I am attempting to remove or disable the title slide, is there a way to do this.


Thanks

I assume you are using the CreateHelloWorld sample.

That in turn relies on PresentationMLPackage.createPackage()

        public static PresentationMLPackage createPackage(SlideSizesWellKnown sz,
                        boolean landscape) throws InvalidFormatException {
               
               
                // Create a package
                PresentationMLPackage pmlPack = new PresentationMLPackage();

                // Presentation part
                MainPresentationPart pp;
                try {
                       
                        pp = new MainPresentationPart();
                        pp.setJaxbElement(
                                        MainPresentationPart.createJaxbPresentationElement(sz, landscape) );
                        pmlPack.addTargetPart(pp);

In there, SlideLayoutPart.createSldLayout() uses:

        public static SldLayout createSldLayout() throws JAXBException {

                ObjectFactory factory = Context.getpmlObjectFactory();
                SldLayout sldLayout = factory.createSldLayout();
               
                CommonSlideData cSld = (CommonSlideData)XmlUtils.unmarshalString(COMMON_SLIDE_DATA,
                                Context.jcPML,
                                CommonSlideData.class);
                cSld.setName("Title Slide");
               
                sldLayout.setCSld( cSld );
                return sldLayout;

So that's where the title slide layout comes from.

You don't need to use it. And of course you can define whatever layout you like.

Probably your best approach is to start with an empty pptx you've created in Powerpoint, which contains the layouts (and master, theme) you want to use.
