Hello,
We are looking into upgrade of current Aspose.Slides library, but encountered an issue with conversion of PPT presentation containing an EMF image to PDF.
Below is the sample code:

final String targetPdfFile  = [PATH] + "PPT_testSample_aspose_23_02.pdf";
final String sourcePptxFile =  [PATH] + "PPT_testSample.pptx";
	   
IPresentation pptx = new Presentation(sourcePptxFile);
PdfOptions saveOptions = new PdfOptions();
saveOptions.setBestImagesCompressionRatio(false);
saveOptions.setJpegQuality((byte)95);
pptx.save(targetPdfFile, SaveFormat.Pdf, saveOptions);

Note that when opened generated PDF output, it shows a border on the right and bottom of the chart image.
Attached is zipped source PPTX sample document, and screenshot illustrating the issue.
This issue is reproducible on both Linux 7.4 and Windows 10 platform with java full version “1.8.0_351-b10”.
Thank you in advance,
Yan.

Try to use this option when converting to PDF to avoid EMF image borders:

saveOptions.setSaveMetafilesAsPng(false);

Hi Stanislav.
Thank you for the quick response.
I tried the option you suggested setSaveMetafilesAsPng(false) and the borders are no longer added, However, now the numbers in the image are no longer shown.
Attached is the zip file containing the input PPT with slide containing EMF image, and the output PDF illustrating the problem.
Please take a look and let me know what am I missing?

Thanks,
Yan
