Hello,

Thanks for your inquiry. Please refer to the below code snippet to accomplish your task.

Code: Select all

            // Create a pdf document with a section
            PdfDocument doc = new PdfDocument();
            PdfSection section = doc.Sections.Add();
            string[] images = { "sample.png", "sample1.png", "sample2.png" };
            foreach(String imageFile in images)
            {       
                //add new page
                PdfPageBase page = doc.Pages.Add();
                //Load a png image from system
                PdfImage image = PdfImage.FromFile(imageFile);
                //Set image display location and size in PDF
                float widthFitRate = image.PhysicalDimension.Width / page.Canvas.ClientSize.Width;
                float heightFitRate = image.PhysicalDimension.Height / page.Canvas.ClientSize.Height;
                float fitRate = Math.Max(widthFitRate, heightFitRate);
                float fitWidth = image.PhysicalDimension.Width / fitRate;
                float fitHeight = image.PhysicalDimension.Height / fitRate;
                page.Canvas.DrawImage(image, 10, 10, fitWidth, fitHeight);
            }
            //save the file
            doc.SaveToFile("image to pdf.pdf");
            doc.Close();
