News of pptx4j

I need to create a PPTX with a few charts and venndiagrams.
For teh charts , I am plannign to use JFreeChart.
The Venndiagram cannot be drawn the same way. For docx I used a sample template with a Venndiagram drawing and changed the sample values to the actuals during runtime.
I was trying the same approach using pptx but cannot get it working.
For word I was using the method

Hello,

Thank you for creating this Java Library!

I need to split input pptx file into a set of slides each stored in the separate output pptx file. When input file gets uploaded to a directory program will be called from my main program (written in PHP) and do the split.

Is it possible to do it with pptx4j? I am beginner in Java so code examples would help.

Thank you!

Hi,
Any one knows how to hyperlink text to a slide while creating the pptx. First I have the text and the slide is added later in the application.

Attached is the complete code that creates the text in a table and the slides.

I tried to create the Relationship

Code: Select all

if(i == 5){
                    org.docx4j.relationships.ObjectFactory factory = new org.docx4j.relationships.ObjectFactory();
                        org.docx4j.relationships.Relationship rel = factory.createRelationship();
                        rel.setType("Namespaces.PRESENTATIONML_SLIDE");
                        rel.setTarget("/ppt/slides/slide"+i+".xml");
                        mainPresentationPart.getRelationshipsPart().addRelationship(rel);
                        System.out.println(rel.getId());
                 }


and added code to link the text ...

Hi,

i am studing at university and my problem is that i must generate from .pptx or .ppt HTML or PDF or SVG format with all the text, images, tables and graphs in my thesis application.
I searched tools which working with ppt/pptx and transforming the data into svg or images(from this images i made a simple web page) but stil i cant transform tables or graphs. Could anyone help me to figure it out? ...

The method of generation of the slideId (and the other Ids) seems to leave the possibility open (if unlikely in general practice) for inserted slides to have the same Id (especially if the pptx is modified on several different occasions). In my particular instance I am looking at how to generated unique Ids for added graphic frame (cNvPr) so I was browsing how it was done for slideIds...

The code seems to be in JaxbPmlPart ...

So I am trying to reproduce the following XML as part of a test for chart addition:

</p:nvGraphicFramePr>
<p:xfrm>
<a:off x="1524000" y="1397000"/>
<a:ext cx="6096000" cy="4064000"/>
</p:xfrm>
<a:graphic>
<a:graphicData uri="http://schemas.openxmlformats.org/drawingml/2006/chart">
<c:chart xmlns:c="http://schemas.openxmlformats.org/drawingml/2006/chart" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" r:id="rId2"/>
</a:graphicData>
</a:graphic>
</p:graphicFrame>

And I get everything to work fine except creating the line:
<c:chart xmlns:c="http://schemas.openxmlformats.org/drawingml/2006/chart" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" r:id="rId2"/>

The code for this relevant portion is:

Graphic g = new Graphic();
GraphicData gd = new GraphicData();
gd.setUri("http://schemas.openxmlformats.org/drawingml/2006/chart");

org.docx4j.dml.chart.ObjectFactory factory = new org.docx4j.dml.chart.ObjectFactory();
CTRelId ...

When I run this sample against a powerpoint with a single slide that has an embedded chart, I get the following:

Exception in thread "main" java.lang.RuntimeException: javax.xml.bind.MarshalException
- with linked exception:

So I am wondering what to read to get started with pptx4j? Can anyone point me in a useful direction? There does not seem to be a tremendous amount of basic documentation to bootstrap from. Any assistance appreciated.

Cheers,
