Insert Image to Slide in Aspose.Slides vs pptx4j

Aspose.Slides - Insert Image to Slide

Below example shows how different images and autoshapes can be added to presentation slides using Aspose.Slides.

Java

 //Instantiate Presentation class that represents the PPTX

Presentation pres = new Presentation();

//Get the first slide

ISlide sld = pres.getSlides().get_Item(0);

//Instantiate the Image class

IPPImage imgx = null;

try{

    imgx = pres.getImages().addImage(new FileInputStream(new File(dataDir + "greentick.png")));

}

catch(IOException e){}

//Add Picture Frame with height and width equivalent of Picture

sld.getShapes().addPictureFrame(ShapeType.Rectangle, 50, 150, imgx.getWidth(), imgx.getHeight(), imgx);

//Write the PPTX file to disk

pres.save(dataDir + "ImageInSlide-Aspose.pptx", SaveFormat.Pptx);

pptx4j - Insert Image to Slide

Below mentioned example shows how different images and autoshapes can be added to presentation slides using Aspose.Slides.

Java

 public static void main(String[] args) throws Exception {

	final Logger log = LoggerFactory.getLogger(Pptx4jAddImageToSlide.class);

	// Where will we save our new .pptx?

	String outputfilepath = dataDir + "ImageInSlide-Pptx4j.pptx";

	// Create skeletal package, including a MainPresentationPart and a SlideLayoutPart

	PresentationMLPackage presentationMLPackage = PresentationMLPackage.createPackage();

	// Need references to these parts to create a slide

	// Please note that these parts *already exist* - they are

	// created by createPackage() above.  See that method

	// for instruction on how to create and add a part.

	MainPresentationPart pp = (MainPresentationPart)presentationMLPackage.getParts().getParts().get(

			new PartName("/ppt/presentation.xml"));

	SlideLayoutPart layoutPart = (SlideLayoutPart)presentationMLPackage.getParts().getParts().get(

			new PartName("/ppt/slideLayouts/slideLayout1.xml"));

	// OK, now we can create a slide

	SlidePart slidePart = presentationMLPackage.createSlidePart(pp, layoutPart,

			new PartName("/ppt/slides/slide1.xml"));

	// Add image part

	File file = new File(dataDir + "greentick.png" );

    BinaryPartAbstractImage imagePart

    	= BinaryPartAbstractImage.createImagePart(presentationMLPackage, slidePart, file);


    // Add p:pic to slide

	slidePart.getJaxbElement().getCSld().getSpTree().getSpOrGrpSpOrGraphicFrame().add(

			createPicture(imagePart.getSourceRelationship().getId()));


	// Do it again on another slide

	SlidePart slidePart2 = presentationMLPackage.createSlidePart(pp, layoutPart,

			new PartName("/ppt/slides/slide2.xml"));

	Relationship rel = slidePart2.addTargetPart(imagePart);

	slidePart2.getJaxbElement().getCSld().getSpTree().getSpOrGrpSpOrGraphicFrame().add(

			createPicture(rel.getId()));

	// All done: save it

	presentationMLPackage.save(new java.io.File(outputfilepath));

	System.out.println("\n\n done .. saved " + outputfilepath);
