I created the following PowerPoint 2007 slide, it has two slides. One a title slide and another with a TwoColumn chart.

I ran the pptx example EditEmbeddedCharts, updating the code to reflect the name difference of the embedded spreadsheet. The program completes with no ERRORS, but does have the following WARN

Code: Select all

I am currently using docx4j to handle creating docx files and it working very nicely. I am now needing to update an existing pptx slide deck replacing current chart data with new values.

I did a git clone the other day, built the source and then try to run the EditEmbeddedCharts java sample under pptx4j.

Hi There,

I have to add a capability that is export a jsp (rendered as html page) as ppt file. Previously export jsp as excel and as pdf has been done.

Please suggest a way or share experience about html/jsp to ppt converter.

Many Thanks.

Hello!

I want to be able to replace an embedded .xlsx in a .pptx.

First step I did was create a simple .pptx file in Powerpoint which contains one slide and imported a spreadsheet from Excel in it.

I tried to replace the embedded .xlsx file but ran in to some trouble with corrupted files. Then found out that just doing this causes the .pptx to be corrupt:

Code: Select all

PresentationMLPackage ppt = PresentationMLPackage.load(new File("input.pptx"));

Hello,

I'm working on a project that will take an existing PowerPoint presentation with a number of charts embedded in it, update the data then output a new copy. I've found a few hints in the forum about how this should work but missing is an example for saving the binary data back into the EmbeddedPackagePart. All of the examples I've seen on the forum appear to read in existing spreadsheets from a discreet disk ...

Hello,

We have placeholder images in pptx that we replace dynamically at runtime, the new image size may be bigger then the original placeholder image.
Is there anyway to constrain the size of visible image in pptx.
