How to save a document in Image format using C# and .NET

  1. Add SautinSoft.Document from Nuget.
  2. Load or Create a document.
  3. Save to a Image format.

Let's save each page of the document into image format, like a shown on the picture:

Save as Image

Code explanations

Here we create DocumentPaginator:

 DocumentPaginator dp =  dc.GetPaginator();
Pagination is the process of dividing a document into discrete pages.

namespace Example
    class Program
        static void Main(string[] args)
            // Get your free 30-day key here:   

        /// <summary>
        /// Loads a document and saves all pages as images.
        /// </summary>
        /// <remarks>

        static void SaveToImage()
            string filePath = @"..\..\..\example.docx";
            DocumentCore dc = DocumentCore.Load(filePath);
            string folderPath = Path.GetFullPath(@"Result-files");

            DocumentPaginator dp =  dc.GetPaginator();

            for (int i = 0; i < dp.Pages.Count; i++)
                DocumentPage page = dp.Pages[i];
                // For example, set DPI: 72, Background: White.

                var DPI = new ImageSaveOptions();
                DPI.DpiX = 72;
                DPI.DpiY = 72;
                // Rasterize/convert the page into PNG image.
                SKBitmap image = page.Rasterize(DPI, SautinSoft.Document.Color.White);

                image.Encode(new FileStream(folderPath + @"\Page - " + i.ToString() + ".png", FileMode.Create), SkiaSharp.SKEncodedImageFormat.Png, 100);

            System.Diagnostics.Process.Start(new System.Diagnostics.ProcessStartInfo(folderPath) { UseShellExecute = true });
