To convert a PowerPoint presentation (PPTX) that includes emojis to a PDF using Aspose.Slides for Java, you can follow these steps:
Prepare Your Environment: Ensure you have the Aspose.Slides library added to your Java project.
Load the Presentation: Use the Aspose.Slides API to load your PPTX file that contains the emojis.
Save as PDF: After loading the presentation, you can save it as a PDF file. The Aspose.Slides library supports rendering a wide range of emojis, including standard Unicode emojis, ensuring they appear correctly in the output PDF.
Here is a sample code snippet to demonstrate the process:
import com.aspose.slides.*;
public class ConvertPPTXToPDF {
public static void main(String[] args) {
// Set the path to the presentation file
String dataDir = "path/to/your/presentation.pptx";
String outputPdfPath = "path/to/output/presentation.pdf";
// Load the presentation
Presentation presentation = new Presentation(dataDir);
// Save the presentation as PDF
presentation.save(outputPdfPath, SaveFormat.Pdf);
System.out.println("Presentation converted to PDF successfully.");
}
}
If you encounter any issues with specific emojis not rendering correctly, it may be worth checking the compatibility of those emojis with the Aspose.Slides library.
For more detailed information on rendering emojis and converting presentations to PDF, you can refer to the official documentation on rendering emojis in PowerPoint and the PDF conversion process.

I have done exactly what is stated in the code but it doesn’t work

@martindelacruz,
Thank you for the details. I’ve reproduced the problem with missing emiji and text when converting the PowerPoint presentation to a PDF document. Unfortunately, using Aspose.Slides 25.1 does not solve the issue yet (an error occurs). We apologize for any inconvenience caused.
We have opened the following new ticket(s) in our internal issue tracking system and will deliver their fixes according to the terms mentioned in Free Support Policies.
Issue ID(s): SLIDESJAVA-39624

Hi Andrey,
If it helps, when we run the same code on a Mac, the emojis are not displayed, but the conversion is completed. On Windows, the conversion is truncated.
Hi, we have also test the conversion in aspose.cloud and it works. Emojis are not displayed but conversion is finished without truncated.
I’m attached a new sample, with the pdf downloaded from aspose cloud.

@martindelacruz, @marcoscacabelos,
Our developers have investigated the case. The problem with displaying symbols is caused by the absence of the Segoe UI Emoji font. There is currently no replacement for this font on macOS or Linux. To resolve the issue, use FontsLoader with the Segoe UI Emoji font.
FontsLoader.loadExternalFonts(new String[]{"path_to_the_font_folder"});
