USING THE CODE

Free Spire.Presentation for Java supports embedding a zip file in a new PowerPoint document. The detailed steps are listed below.

l  Create a Presentation instance and set the size of slides using Presentation.getSlideSize().setType() method.

l  Get a specific slide of the document using Presentation.getSlides().get() method.

l  Load a zip file and convert it to a byte[] object.

l  Load an image and add it to the slide as the display icon of the zip file using Presentaion.getImages().append() method.

l  Insert the zip file as an OLE object to the specific slide using ISlide.getShapes().appendOleObject() method.

l  Get the fill properties object of OleObject image using IOleObject.getSubstituteImagePictureFillFormat() method, and then set the embedded image using PictureFillFormat.getPicture().setEmbedImage() method.

l  Save the document to another file using Presentation.saveToFile() method.

        //Insert the zip file as an OLE object to the first slide
        Rectangle2D rect = new Rectangle2D.Float(60, 60, image.getWidth(), image.getHeight());
        IOleObject oleObject = slide.getShapes().appendOleObject("zip", data, rect);
        oleObject.getSubstituteImagePictureFillFormat().getPicture().setEmbedImage(oleImage);
        oleObject.setProgId("Package");

        //Save to file
        presentation.saveToFile("output/InsertZip.pptx", FileFormat.PPTX_2013);
    }
