Adding images to a generated powerpoint document?

[lokkju]

Hey all, hoping someone can point me in the right direction. I'm trying to find how I can add linked imaged to a PowerPoint slide. I've written the necessary PML, but am unsure how to add the correct relationship to the file in the /ppt/media folder... ideas?

Please have a look at the docx sample http://dev.plutext.org/svn/docx4j/trunk ... Image.java

You'll have to adapt it a bit, but the basic pattern (for adding the image part and a relationship pointing to it) should be the same

If you write something which could form part of pptx4j, please consider contributing it. Thanks!

The problem with the current docx implementation is that it depends on having a WordprocessingMLPackage passed in for all the image helper functions. I would suggest trying to move the code over to depend on a generic OpcPackage.

I eventually got it working using just the BinaryPart - here is a sample snippet:

Code: Select all

        // BinaryPart
        BinaryPart binaryPart = new BinaryPart(new PartName("/ppt/media/image" + this.imageId + ".jpeg"));
        binaryPart.setBinaryData(image);
        binaryPart.setContentType(new  org.docx4j.openpackaging.contenttype.ContentType(org.docx4j.openpackaging.contenttype.ContentTypes.IMAGE_JPEG));
        binaryPart.setRelationshipType(Namespaces.IMAGE);

        Relationship bpRelationship = slidePart.addTargetPart(binaryPart);


        Pic pic = new Pic();
        // nvPicPr
        pic.setNvPicPr(new Pic.NvPicPr());
        pic.getNvPicPr().setCNvPr(new CTNonVisualDrawingProps());
        pic.getNvPicPr().setCNvPicPr(new CTNonVisualPictureProperties());
        pic.getNvPicPr().getCNvPicPr().setPicLocks(new CTPictureLocking());
        pic.getNvPicPr().setNvPr(new NvPr());
        pic.getNvPicPr().getCNvPr().setId(this.imageId);
        pic.getNvPicPr().getCNvPr().setName(name);
        pic.getNvPicPr().getCNvPr().setDescr(description);
        pic.getNvPicPr().getCNvPicPr().getPicLocks().setNoChangeAspect(true);

        pic.setBlipFill(new CTBlipFillProperties());
        pic.getBlipFill().setBlip(new CTBlip());
        pic.getBlipFill().getBlip().setEmbed(bpRelationship.getId());
        pic.getBlipFill().getBlip().setCstate(STBlipCompression.PRINT);
        pic.getBlipFill().setStretch(new CTStretchInfoProperties());
        pic.getBlipFill().getStretch().setFillRect(new CTRelativeRect());

        pic.setSpPr(new CTShapeProperties());
        pic.getSpPr().setXfrm(new CTTransform2D());
        pic.getSpPr().getXfrm().setOff(new CTPoint2D());
        pic.getSpPr().getXfrm().getOff().setX(0);
        pic.getSpPr().getXfrm().getOff().setY(0);
        pic.getSpPr().getXfrm().setExt(new CTPositiveSize2D());
        pic.getSpPr().getXfrm().getExt().setCx(9144000);
        pic.getSpPr().getXfrm().getExt().setCy(6858000);
        pic.getSpPr().setPrstGeom(new CTPresetGeometry2D());
        pic.getSpPr().getPrstGeom().setPrst(STShapeType.RECT);
        pic.getSpPr().getPrstGeom().setAvLst(new CTGeomGuideList());
        slidePart.getJaxbElement().getCSld().getSpTree().getSpOrGrpSpOrGraphicFrame().add(pic);
    }
