Hi,

When converting a PPTX to PDF with meta file as vector images, all text was lost in the PDF.

Code:

var ppt = new Presentation(@“test.pptx”);
var option = new PdfOptions();
option.SaveMetafilesAsPng = false;
ppt.Save(@“test.pdf”, SaveFormat.Pdf, option);

I’ve attached the test files and a screenshot for your reference. Could you please kindly check?

Hi,

Thanks for your updates. I have today tried the new release and found that the issue was indeed fixed in the latest version if I used the default compliance option (PDF15).

However, when I used the other compliance option PDF1Ab, it produced an exception
System.NotImplementedException: The method or operation is not implemented.

Code:
var doc = new Presentation(@".\test.pptx");
var saveOptions = new PdfOptions();
saveOptions.Compliance = PdfCompliance.PdfA1b;
saveOptions.SaveMetafilesAsPng = false;
doc.Save(@".\out.pdf", SaveFormat.Pdf, saveOptions);

Note that if I use MS Office Powerpoint to save the PPTX to PDF using PDF/A compliant option, it can actually produce the result properly.
