Data in table missing when a PDF with watermark is exported to PPTX


I ran into an issue when exporting a PDF with a table and a watermark to PPTX. Some data values are missing from the table near the watermark text. The conversion is fine without the watermark.

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

I’ve attached the source PDF & PPTX in a zip.

Archive.zip (6.3 MB)



Can you point me out what fields are missing and on what page?

I am using Aspose.Pdf version 23.2

public void Logic() throws Exception
    var doc = new com.aspose.pdf.Document(PartialPath + "_input.pdf");

    doc.save(PartialPath + "_output.pptx", SaveFormat.Pptx);

The input and output:

ConvertToPptx_2_input.pdf (157.5 KB)

TableDoesNotRenderComplete_2_output.zip (296.5 KB)

The value 3,897 in the 6th column, row SN 5 is missing in PPTX conversion.

There also another issue with conversion with watermark present. Some PDFs with watermarks have a white box around the watermark. Can be seen when a background color is added to slide

See example:
