We’re facing issue of background color of Bar graph getting blacked out on some of the labels while converting PDF into PPT.
Please find the attached PDF and screenshot of ppt file generated.

We need more details to investigate the case. Please share the following additional information:

  • code example that reproduces the problem

Thank you for your response.

  "PptxOutput.pptx", com.aspose.pdf.SaveFormat.Pptx);
            Presentation presentation = new Presentation("PptxOutput.pptx");

Thank you for the additional information. It looks like the problem does not appear with Aspose.PDF for Java 23.9. We recommend using the latest version of Aspose.PDF for Java.

I’ve moved this forum thread to Aspose.Total forum.
