How to convert word to tiff using C#, VB.NET

Platform: WinForms |
Control: DocIO

Syncfusion Essential DocIO is a .NET Word library used to create, read, and edit Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can convert Word to TIFF in C# and VB.NET.

Steps to convert Word to TIFF using C#:

  1. Create a new C# console application project.Create Console application in Visual Studio
  2. Install Syncfusion.DocIO.WinForms NuGet package as a reference to your .NET Framework applications from the NuGet.org.Add DocIO NuGet package reference to the project
  3. Include the following namespace in the Program.cs file.

C#

using Syncfusion.DocIO.DLS;

VB

Imports Syncfusion.DocIO.DLS
  1. Use the following code to convert Word to TIFF.

C#

// Loads an existing Word document.
WordDocument wordDocument = new WordDocument("Template.docx");
//Converts word document to image
Image[] images = wordDocument.RenderAsImages(ImageType.Bitmap);
//Closes the Word document instance.
wordDocument.Close();
 
#region Tiff conversion
ImageCodecInfo encoderInfo = GetEncoderInfo("image/tiff");
//Initialize EncoderParameters that contain specified number of Encoderparameter objects
EncoderParameters encoderParams = new EncoderParameters(2);
//Initialize EncoderParameter
EncoderParameter parameter = new EncoderParameter(Encoder.Compression, (long)EncoderValue.CompressionNone);
encoderParams.Param[0] = parameter;
// Initializes the new instance for EncoderParameter.
parameter = new EncoderParameter(Encoder.SaveFlag, (long)EncoderValue.MultiFrame);
encoderParams.Param[1] = parameter;
Image tiff = null;
for (int i = 0; i < images.Length; i++)
{
    if (i == 0)
    {
        tiff = images[i];
        // Saves the tiff image into local disk.
        tiff.Save("..//..//Output//WordToTiff.tiff", encoderInfo, encoderParams);
    }
    else
    {
        Image image = images[i];
        // Initializes the new instance for EncoderParameter.
        parameter = new EncoderParameter(Encoder.SaveFlag, (long)EncoderValue.FrameDimensionPage);
        encoderParams.Param[1] = parameter;
        // Adds the subsequent image to save into the local disk.
        tiff.SaveAdd(image, encoderParams);
    }
}
#endregion

VB

'Loads an existing Word document.
Dim wordDocument As WordDocument = New WordDocument("..\..\Template.docx")
'Converts word document to image
Dim images As Image() = wordDocument.RenderAsImages(ImageType.Bitmap)
'Closes the Word document instance.
wordDocument.Close()
Dim encoderInfo As ImageCodecInfo = GetEncoderInfo("image/tiff")
'Initialize EncoderParameters that contain specified number of Encoderparameter objects
Dim encoderParams As EncoderParameters = New EncoderParameters(2)
'Initialize EncoderParameter
Dim parameter As EncoderParameter = New EncoderParameter(Encoder.Compression, CLng(EncoderValue.CompressionNone))
encoderParams.Param(0) = parameter
'Initializes the New instance for EncoderParameter.
parameter = New EncoderParameter(Encoder.SaveFlag, CLng(EncoderValue.MultiFrame))
encoderParams.Param(1) = parameter
Dim tiff As Image = Nothing
For i = 0 To images.Length - 1
    If i = 0 Then
        tiff = images(i)
        'Saves the tiff image into local disk.
        tiff.Save("..\..\Output\WordToTiff-1.tiff", encoderInfo, encoderParams)
    Else
        Dim image As Image = images(i)
        'Initializes the New instance for EncoderParameter.
        parameter = New EncoderParameter(Encoder.SaveFlag, CLng(EncoderValue.FrameDimensionPage))
        encoderParams.Param(1) = parameter
        'Adds the subsequent image to save into the local disk.
        tiff.SaveAdd(image, encoderParams)
    End If
Next
  1. Include the following helper method.

C#

private static ImageCodecInfo GetEncoderInfo(String mimeType)
{
    ImageCodecInfo[] encoders = ImageCodecInfo.GetImageEncoders();
    foreach (ImageCodecInfo imageCodecInfo in encoders)
    {
        if (imageCodecInfo.MimeType == mimeType)
            return imageCodecInfo;
    }
    return null;
}

VB

Private Shared Function GetEncoderInfo(ByVal mimeType As String) As ImageCodecInfo
    Dim encoders As ImageCodecInfo() = ImageCodecInfo.GetImageEncoders()
 
    For Each imageCodecInfo As ImageCodecInfo In encoders
        If imageCodecInfo.MimeType = mimeType Then Return imageCodecInfo
    Next
 
    Return Nothing
End Function

Input Word document as follows. Input Word document

By executing the program, you will get the output TIFF as follows. Generated TIFF Image

Take a moment to peruse the documentation, where you can find basic Word document processing options along with features like mail merge, merge and split documents, find and replace text in the Word document, protect the Word documents, and most importantly PDF and Image conversions with code examples.
