In the first place, we will introduce you how to transform and convert TIFF with single page to PDF document using free C# demo code. In this coding demo, it only needs you to input your source (.tif) image file, and then a PDF document will be generated automatically. Once you run C# code example below, you will get a single page PDF document, which has the same page size as your TIFF image.
using System; using PQScan.ImageToPDF; namespace TiffToPDF { class Program { static void Main(string[] args) { // Generate an instance of PQScan.ImageToPDF.PDFConverter object. PDFConverter converter = new PDFConverter(); // Choose PDF page layout. If you choose ImageSize, // converted PDF page will has the same size and quality as your source image. converter.PageSizeType = PageSizeMode.ImageSize; // Set input Tiff image with single page from local file on disk. string[] imgFiles = new string[1] { "single-page.tif" }; // Set output PDF file name. string outFile = "single-page.pdf"; // Get PDF from single page Tiff image. converter.CreatePDF(imgFiles, outFile); } } }
