Reading and Writing Doughnut Chart Generates a Corrupted PPTX File in Java

Aspose.Slides Product Family
,
1

I have simple program

public class slidesTest {

  public static void main(String[] args) throws IOException {
    Presentation template = load("DonutChart.pptx");
    template.save("DonutOut.pptx", SaveFormat.Pptx);
  }

  private static Presentation load(String path) throws IOException {
    Presentation presentation;
    try (FileInputStream is = new FileInputStream(path)) {
      presentation = new Presentation(is);
    }
    return presentation;
  }
  
}

That reads a one doughnut slide from a pptx file, and then writes it to another file (without any manipulation)
The resulting file is corrupt, and PPT cannot read it.

Attached is the input file
slides.zip (18.4 KB)
