News of pptx4j

Hi,

I'm still working on PPTX document copy, and I have troubles with charts.
It works fine when I copy a Chart part, but when I try to add an embedded XLSX object, I see following line in the log:

Code: Select all

org.docx4j.openpackaging.parts.relationships.RelationshipsPart  - True - will delete relationship with target ../embeddings/Microsoft_Office_Excel_Worksheet1.xlsx

It comes right after doing this:

Code: Select all

chartPart.addTargetPart(xlsxPart);

SaveToZipFile throws an Exception:

Code: Select all

org.docx4j.openpackaging.exceptions.Docx4JException: Failed to add parts from relationships

Hi Jason,

When I add an excel in PPTX as table , it throws null pointer java.lang.IllegalArgumentException: Unexpected node type: null.

Can you please advise if this is possible?

I need to color code PPTX based on the values.

I thought I can add excel and add formula to the cell to make it work .. but when I add excel (with or with out formatting cell ) the parsing fails.

It works great with ...

Hi ,

I was able to read and replace the excel file inside the PPTX but after saving the excel has the latest file with values but the chart is not getting rendered.

Can some one shed ...

Hi,

I need to merge several PPTX files into a single presentation.
I've already created a class which performs merging of slides with simple content, but I don't know how to copy images.

When I use XmlUtils.deepCopy() to copy a slide with images, new slide requires RelationshipsPart which does not exist.
How can I copy the RelationshipsPart from the source presentation, and assign it to the new slide in the destination PPTX file?

Thanks,
Dmitriy

This is my first post in these forums, so let me begin with a thank you. I appreciate the work that you have done here and feel fortunate to be able to leverage this code in our application.

It may be my lack of experience with the interface, but would it be interesting/possible to perform an incremental save of a document (in my case a PPTX package)? I notice that there is an internal map ...

Hi,

I want to edit a ppt that has charts and some table with numeric data ($ and number). The charts that I have to create are fixed/static. I need to just edit the data through a program dynamically.

I am never used dox4j and exploring if it suffice my requirements.

Appreciate if someone can share some sample program and a link to documentation for dox4j.

Thanks,
Pravin

Hi Jason,

I've had a problem for opening potx with pptx4j. In fact, there was an error (/ppt/presentation.xml unreconized part). I think it's due to the addition of the presentation part when the file is a potx (in JaxbPmlPart, the function newPartForContentType add a part only if it's a ContentTypes.PRESENTATIONML_MAIN and not a ContentTypes.PRESENTATIONML_TEMPLATE).
I submit you a patch with this change, but I don't know if it could cause failure on some cases.

Thank ...

Jason,

Any thoughts on how one might go about adding slide notes to a deck? I have been looking at it for a few days, and cant seem to crack it.

Thanks.

See http://www.docx4java.org/trac/docx4j/changeset/1684 for how to add an image to a slide.

Note this will need to be modified if you use anything earlier than today's nightly (which I'm still to create) or docx4j 2.7.1, since it is only from yesterday that BinaryPartAbstractImage.createImagePart has had a File signature. If you use byte, you'll be able to use this with earlier versions of pptx4j.
