We have one PPTX file, after conversion to PDF file, some of text at the original PPTX won’t be displayed, instead it is hidden. However if I copy the text, I could see those hidden text.
the code is very simple:
private void ConvertFromPptX(Stream inputStream, Stream outputStream)
{
Aspose.Slides.Pptx.PresentationEx presentation = new Aspose.Slides.Pptx.PresentationEx(inputStream);
presentation.Save(outputStream, Aspose.Slides.Export.SaveFormat.Pdf);
}
Here the inputStream and outStream are stream for input file and output file.
Both PPTX and converted PDF file are attached at this post.
Please let us know what we are missing here.
