Syncfusion Essential DocIO is a .NET Core 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 AWS Elastic Beanstalk.

Steps to convert Word document to Image in AWS Elastic Beanstalk

Step 1: Create a new ASP.NET Core Web application (Model-View-Controller) project.

Step 2: Install the following Nuget packages in your application from Nuget.org.

• Syncfusion.DocIORenderer.Net.Core
• SkiaSharp.NativeAssets.Linux.NoDependencies v2.88.8

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 HomeController.cs file.

C#

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

Step 4: A default action method named Index will be present in HomeController.cs. Right click on Index method and select Go To View where you will be directed to its associated view page Index.cshtml.

Step 5: Add a new button in the Index.cshtml as shown below.

C#

@{
    Html.BeginForm("ConvertWordtoImage", "Home", FormMethod.Get);
    {
        <div>
            <input type="submit" value="Convert Word to Image" style="width:200px;height:27px" />
        </div>
    }
    Html.EndForm();
}

Step 6: Include the below code snippet in the Homecontroller.cs file to convert a Word document to image and download it.

C#

public ActionResult ConvertWordtoImage()
{
    //Open the file as Stream
    using (FileStream docStream = new FileStream(Path.GetFullPath("wwwroot/Data/Input.docx"), FileMode.Open, FileAccess.Read))
    {
        //Loads file stream into Word document
        using (WordDocument wordDocument = new WordDocument(docStream, FormatType.Docx))
        {
            //Hooks the font substitution event.
            wordDocument.FontSettings.SubstituteFont += FontSettings_SubstituteFont;
            //Instantiation of DocIORenderer
            using (DocIORenderer render = new DocIORenderer())
            {
                //Convert the first page of the Word document into an image.
                Stream imageStream = wordDocument.RenderAsImages(0, ExportImageFormat.Jpeg);
                //Unhooks the font substitution event after converting to image.
                wordDocument.FontSettings.SubstituteFont -= FontSettings_SubstituteFont;
                //Reset the stream position.
                imageStream.Position = 0;
                //Save the image file.
                return File(imageStream, "application/jpeg", "WordToImage.Jpeg");
            }
        }
    }
}

private static void FontSettings_SubstituteFont(object sender, SubstituteFontEventArgs args)
{
    if (args.OrignalFontName == "Calibri" && args.FontStyle == FontStyle.Regular)
    {
        args.AlternateFontStream = new FileStream(Path.GetFullPath("wwwroot/Fonts/calibri.ttf"), FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
