Hi,

Code snippet :

inputFile : is the ppt file location
outputFile : is the location + filename to save output pdf file

Presentation presentation = new Presentation(inputFile);
presentation.save(outputFile, SaveFormat.PDF);

I have attached ISIR.ppt as a sample ppt file.

Hi Anurag,


I have updated my Open JDK version to 6b24-1.11.3-1ubuntu0.10.04.1 and have been able to generate the PDF properly. As you have mentioned that even a simplest empty presentation is not being rendered to PDF on your end, it seems there is some issue on your end and I would suggest you to please try re-installing the JDK on your end. Also install the JDK update for running in headless mode.

For your kind reference, I have shared the sample Eclipse project along with used Jar Files. You can observe the sample project and use it Jar files shared on your end.

Many Thanks,
