How to convert word to tiff using C#, VB.NET
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#:
- Create a new C# console application project.
- Install Syncfusion.DocIO.WinForms NuGet package as a reference to your .NET Framework applications from the NuGet.org.
- Include the following namespace in the Program.cs file.
C#
using Syncfusion.DocIO.DLS;
VB
Imports Syncfusion.DocIO.DLS
- 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

If i = 0 Then

encoderParams.Param(1) = parameter
'Adds the subsequent image to save into the local disk.
tiff.SaveAdd(image, encoderParams)
End If

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