ODP conversion to PDF not working

[jan.zanda]

Hello, I have a problem with ODP conversion to PDF.
Spire.Office version: 9.12.0
Java: Amazon-Corretto 11 and 21 all systems multiple minor versions (mac, windows, linux)

Any ODP file (incl. the one attached) ends up in

Code: Select all

The fail occurs in method loadFromStream in this code:

Code: Select all

   //create a Presentataion instance
        Presentation presentation = new Presentation();
        //set font path
        if (!StringUtils.isEmpty(externalFontPath)) {
            presentation.setCustomFontsFolder(externalFontPath);
        }
        //load the sample PowerPoint file
        // !! HERE IT FAILS !!
        presentation.loadFromStream(file, FileFormat.AUTO);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        //save to PDF file

        presentation.saveToFile(baos, com.spire.presentation.FileFormat.PDF);
        presentation.dispose();
        return new ByteArrayInputStream(baos.toByteArray());

Is there a workaround?

Hi,

Thanks for your feedback.
I tested your ODP file but didn't encounter the same exception as yours. Please confirm if the filestream you passed to the loadFromStream method here is a correctly formatted ODP file stream. You can directly verify loading the ODP file like below.

Code: Select all

presentation.loadFromFile("data/file_example_ODP_500kB.odp", FileFormat.ODP);

Besides, I will further try the Amazon-Corretto 11 and 21 JDK and give you feedback ASAP.

Yes, sadly, it behaves the same this way. The same exception.

Thanks

Hi Jan,

Thanks for your feedback.
I tested your file with the Amazon-Corretto 11 Windows JDK, but still can't reproduce your issue. Here I uploaded my executable jar, please directly use the command: java -jar ClientTest.jar to test on your side. If the issue still occurs, please provide your testing environment, such as Windows 10, 64 bit.

Thank You, it seems to be a dependency conflict, there seems to be a library interfering. We should fix this on our end.
