Chart Label Is Rendered Black when Converting from PDF to PPTX in Java


I ran into an issue when converting a chart in PDF to PPTX. Screenshot 2023-03-02 at 10.02.29 AM.png (67.3 KB).

The column chart’s last label is rendered with a black background which is not present in the source PDF. Attached is the PDF for reference.

DRA.pdf.zip (45.6 KB)

Version used: 23.2
OS: macOS Ventura

Could you please take a look?

Thank you for contacting support.

Please share the following additional files and information:

  • code example that reproduces the problem with the chart
  • output PPTX file
  • JDK version in your app

The JDK version is 17 and the code is just simple conversion:

var fileName = "HRA";
try (Document document = new Document("src/main/java/" + fileName + ".pdf")) {
       document.save("saved.pptx", SaveFormat.Pptx);

The PPTX is attached.
