Thanks in advance for any support. Below is a snippet of the code we use to generate pdf's from powerpoints.
using (var tempStream = new MemoryStream())
{
presentation.Save(tempStream);
// Need to "open" a presentation to save it to a PDF, cannot save presentation from Create
using (var temporaryPresentation = Presentation.Open(tempStream))
{
temporaryPresentation.ChartToImageConverter = new ChartToImageConverter();
var presentationToPdfConverterSettings = new PresentationToPdfConverterSettings
{
SlidesPerPage = SlidesPerPage.One,
PublishOptions = PublishOptions.Slides,
PdfConformanceLevel = PdfConformanceLevel.Pdf_A1B,
OptimizeIdenticalImages = true
};
presentationToPdfConverterSettings.PublishOptions = PublishOptions.Slides;
presentationToPdfConverterSettings.ShowHiddenSlides = false;
presentationToPdfConverterSettings.ImageQuality = 100;
presentationToPdfConverterSettings.ImageResolution = 100;
var pdfDocument = PresentationToPdfConverter.Convert(temporaryPresentation, presentationToPdfConverterSettings);
pdfDocument.Save(memoryStream);
pdfDocument.Close(true);
}
}
