Codecs: How to convert DOCX to TIFF?

In This Topic

VintaSoft Imaging .NET SDK renders DOCX page when converting DOCX document to a TIFF file.

For executing code below it is necessary:

VintaSoft Imaging .NET SDK (Vintasoft.Shared.dll; Vintasoft.Imaging.dll; Vintasoft.Imaging.Gdi.dll or Vintasoft.Imaging.Drawing.SkiaSharp.dll)
VintaSoft Office .NET Plug-in (Vintasoft.Imaging.Office.OpenXml.dll)
System.IO.Packaging nuget-package (nuget-package is used by Vintasoft.Imaging.Office.OpenXml.dll)
System.Drawing.Common nuget-package (nuget-package is necessary if GDI+ should be used as the 2D drawing engine in VintaSoft Imaging .NET SDK) or
SkiaSharp nuget-package (nuget-package is necessary if SkiaSharp should be used as the 2D drawing engine in VintaSoft Imaging .NET SDK)

Here is C#/VB.NET code that shows how to convert DOCX document to a TIFF file using ImageCollection and TiffEncoder classes:

/// <summary>
/// Converts DOCX document to TIFF file using ImageCollection and TiffEncoder classes.
/// DOCX document is rendered with specified resolution.
/// </summary>
public static void ConvertDocxToTiff(string docxFileName, string tiffFileName, float dpi)
{
    // specify that VintaSoft Imaging .NET SDK should use GDI+ for drawing of 2D graphics
    Vintasoft.Imaging.Drawing.Gdi.GdiGraphicsFactory.SetAsDefault();
    // specify that VintaSoft Imaging .NET SDK should use SkiaSharp for drawing of 2D graphics
    //Vintasoft.Imaging.Drawing.SkiaSharp.SkiaSharpDrawingFactory.SetAsDefault();

    // create image collection
    using (Vintasoft.Imaging.ImageCollection imageCollection = new Vintasoft.Imaging.ImageCollection())
    {
        // add DOCX document to collection
        imageCollection.Add(docxFileName);

        // set rendering settings
        imageCollection.SetRenderingSettings(new Vintasoft.Imaging.Codecs.Decoders.RenderingSettings(dpi, dpi));

        // create TiffEncoder
        using (Vintasoft.Imaging.Codecs.Encoders.TiffEncoder tiffEncoder = 
            new Vintasoft.Imaging.Codecs.Encoders.TiffEncoder(true))
        {
            // set TIFF compression to Zip
            tiffEncoder.Settings.Compression = 
                Vintasoft.Imaging.Codecs.ImageFiles.Tiff.TiffCompression.Zip;

            // save images of image collection to TIFF file using TiffEncoder
            imageCollection.SaveSync(tiffFileName, tiffEncoder);
        }

        // dispose images
        imageCollection.ClearAndDisposeItems();
    }
}
