News of pptx4j

Hey,

I'm having some trouble transforming a .pptx file to html. Here is the code



File pptx = new File("some_path");
try {
PresentationMLPackage source = PresentationMLPackage.load(pptx);
Iterator partIterator = source.getParts().getParts().entrySet().iterator();
while (partIterator.hasNext()) {

Map.Entry pairs = (Map.Entry) partIterator.next();

Part p = (Part) pairs.getValue();
if (p instanceof SlidePart) {
ResolvedLayout rl = ((SlidePart) p).getResolvedLayout();

System.out.println(XmlUtils.marshaltoString(rl.getShapeTree(), false, true, Context.jcPML,
"http://schemas.openxmlformats.org/presentationml/2006/main", "spTree", GroupShape.class));

SvgExporter.svg(source, rl);
}
}
} catch (Docx4JException e) {
e.printStackTrace();
} catch (Exception e) ...

http://dev.plutext.org/trac/docx4j/changeset/1080 is a JAXB representation of SVG 1.1, generated using XJC.

This will be used to convert shapes to SVG.

It could also be used as inside libraries which convert EMF/WMF to SVG.

As of changeset 1044, docx4j can load and save OpenXML PresentationML packages.

Loading a pptx is as simple as:

Code: Select all

PresentationMLPackage presentationMLPackage = PresentationMLPackage.load(file);   


Saving is:

Code: Select all

presentationMLPackage.save(file);

Using the same approach as for docx documents, it represents each part as a JAXB content tree.

To create a "Hello World" presentation, see http://dev.plutext.org/trac/docx4j/browser/trunk/docx4j/src/pptx4j/java/org/pptx4j/samples

All the code you need is in docx4j (docx4j-nightly-20100118.jar). (If building from source, be sure to add src/pptx4j/java to your path.)
