//Open the existing PowerPoint presentation with loaded stream.
using (IPresentation pptxDoc = Presentation.Open(assembly.GetManifestResourceStream("Convert_PowerPoint_Presentation_to_Image.Assets.Input.pptx")))
{
//Initialize the PresentationRenderer.
pptxDoc.PresentationRenderer = new PresentationRenderer();
//Converts the first slide into image.
Stream stream= pptxDoc.Slides[0].ConvertToImage(ExportImageFormat.Jpeg);
//Reset the stream position.
stream.Position = 0;
//save and Launch the image file.
SaveService saveService = new();
saveService.SaveAndView("PPTXtoImage.Jpeg", "application/jpeg", stream as MemoryStream);
}
Step 7: Run the Application.
