Text is extra bold when converted from PDF to PPTX


When converting a PDF to PPTX, bold text in the PDF becomes extra bold in the PPTX. This issue also exists in the DOC export as reported in DOCX bold issue.


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

After playing around with the document, I noticed it is because the font used is Bold.

Then when the conversion happened, the text was bold again in PPTX, so like you said, it is bold twice.

All I can think of is to use Aspose.Slides to change the font to one that is not bold. Following a similar pattern to the one, I suggested in your other post.

But how to achieve that working on a PPTX will have to be asked in the Aspose.Slides forum, as I do not have the technical knowledge to help you with that.

We’re are adding the footer to the Excel sheet before converting to PDF with the following code. Is there something in the code causing this? Is this why the PDF has bold fonts

String date = "March 14, 2023";
pageSetup.setFooter(0, "&\"Arial\"&8&K02-074&K444444&B" + date + "&B");

Sample code:

String location = ""; // Give xlsx location
Workbook book = new Workbook(location);

        var pageSetup = book.getWorksheets().get(0).getPageSetup();
        var date = "Sep 27, 2022";
        pageSetup.setFooter(0, "&\"Arial\"&8&K02-074&K444444&B" + date + "&B");

        // save EXCEL as PDF
        book.save("pdfOutput.pdf", com.aspose.cells.SaveFormat.AUTO);

        // load the PDF file using Document class
        try (Document document = new Document("pdfOutput.pdf")) {
            // save document in DOC format
            document.save("output.pptx", com.aspose.pdf.SaveFormat.Pptx);

Could you please take a look?



Can you please attach the PDF generated from Aspose.Cells?

This forum is exclusive for support for Aspose.Pdf. There may be some things in the Aspose.Cells API I do not know.

So I will take the Pdf document as my input for my research, not the Excel document.

The PDF generated is attached. The “Sep 27, 2022” date in footer is converted from the setFotter function call earlier in Excel PageSetup. This PDF is converted to DOCX which contains the double bold issue.
