Syncfusion^® DocIO is a .NET Word library used to create, read, edit, and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can convert a Word document to image in WPF.

Steps to convert Word document to Image in WPF

• Visual Studio
• JetBrains Rider

Prerequisites:

• Visual Studio 2022.
• Install .NET desktop development workload with necessary .NET Framework SDK.

Step 1: Create a new WPF application project.

Step 2: Install the Syncfusion.DocIO.Wpf NuGet package as a reference to your WPF application from NuGet.org.

NOTE

Starting with v16.2.0.x, if you reference Syncfusion^® assemblies from trial setup or from the NuGet feed, you also have to add “Syncfusion.Licensing” assembly reference and include a license key in your projects. Please refer to this link to know about registering Syncfusion^® license key in your application to use our components.

Step 3: Include the following namespaces in the MainWindow.xaml.cs file.

C#

using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;

Step 4: Add a new button in MainWindow.xaml to convert Word document to image file as follows.

C#

<Button Click="btnConvert_Click" VerticalAlignment="Center" Height="30" BorderBrush="LightBlue" HorizontalAlignment="Center" Width="150">
    <Button.Background>
        <LinearGradientBrush EndPoint="0.5,-0.04" StartPoint="0.5,1.04">
            <GradientStop Color="#FFD9E9F7" Offset="0"/>
            <GradientStop Color="#FFEFF8FF" Offset="1"/>
        </LinearGradientBrush>
    </Button.Background>
    <StackPanel Orientation="Horizontal" Height="23" Margin="0,0,0,-2.52" VerticalAlignment="Bottom" HorizontalAlignment="Right" Width="100" RenderTransformOrigin="0.5,0.5">
        <StackPanel.RenderTransform>
            <TransformGroup>
                <ScaleTransform/>
                <SkewTransform/>
                <RotateTransform Angle="-0.226"/>
                <TranslateTransform/>
            </TransformGroup>
        </StackPanel.RenderTransform>
    <Image Name="image2" Margin="2" HorizontalAlignment="Center" VerticalAlignment="Center" />
    <TextBlock Text="Word to Image" Height="38" Width="187" Margin="0,4,0,3" TextWrapping="WrapWithOverflow" />
</StackPanel>
</Button>

Step 5: Add the following code in btnConvert_Click to convert Word document to image with simple text.

C#

using (WordDocument document = new WordDocument("Input.docx", FormatType.Docx))
{
    //Convert the first page of the Word document into an image.
    System.Drawing.Image image = document.RenderAsImages(0, ImageType.Bitmap);
    //Save the image as jpeg.
    image.Save("WordToImage.Jpeg", ImageFormat.Jpeg);
}

Step 6: Build the project.

Click on Build → Build Solution or press Ctrl+Shift+B to build the project.

Step 7: Run the project.

Click the Start button (green arrow) or press F5 to run the app.
