Hi,

I am using PPTx to PDF conversion using Aspose and I am able to stop wrapping in legends in PPTx, however in the generated PDF the legend is wrapping. And this is what am using

  com.aspose.slides.ILegend legend = chart.getLegend();
  if ( legend != null )
  {
    legend.setOverlay( false );
    legend.setPosition( com.aspose.slides.LegendPositionType.Right );
    legend.setTextWrapType(com.aspose.slides.TextWrapType.None);

Could you please guide us here with this wrap issue

Cause

It appears that even though you’ve set the TextWrapType to None for the chart legend in your PPTX file, the generated PDF still displays the legend text wrapping. This issue can arise due to differences in text rendering between the PPTX and PDF formats.

Solution

To prevent the legend text from wrapping in the generated PDF, you should explicitly adjust the legend’s width. By setting a fixed width for the legend, you can ensure that the text remains unwrapped. Here’s how you can implement this:

Code

// Access the chart and its legend
com.aspose.slides.ILegend legend = chart.getLegend();
if (legend != null) {
    legend.setOverlay(false);
    legend.setPosition(com.aspose.slides.LegendPositionType.Right);
    legend.setTextWrapType(com.aspose.slides.TextWrapType.None);
    
    // Set a fixed width for the legend
    legend.setWidth(200); // Adjust the width as necessary
}

// Save the presentation as PDF
presentation.save("output.pdf", SaveFormat.Pdf);

Next Steps

  1. Adjust the width value based on your specific needs to ensure the legend fits without wrapping.
  2. Test the PDF generation again to confirm that the issue is resolved.
  3. If the problem persists, review any other settings or properties that might influence the legend’s appearance.

Please implement these changes and let me know if you need further assistance!

legend.setWidth(200); is not working, still the wrap is on

@ysomaraju,

Thanks for the sample files.

I was able to reproduce the issue as you mentioned by converting your template PowerPoint presentation file to PDF. I found, in the generated PDF, some legend items are wrapping unnecessarily for the Pie chart. It should display legend items as shown in MS PowerPoint app.

Presentation presentation = new Presentation("d:\\files\\LW Story Board.pptx");
presentation.save("d:\\files\\output1.pdf" , com.aspose.slides.SaveFormat.Pdf);
