How to convert a Word DOCX to a PNG Array in C# .NET Framework

Converting document files into sets of single-page images is quite a challenge. If you can overcome the initial parsing of the format, then you must render it, rasterize it, convert to PNG, and finally split it into pages. All of that is a huge headache in C#, so I’m going to show you a much simpler way of getting this done using an API.

First we install our client package using this command here:

Install-Package Cloudmersive.APIClient.NET.DocumentAndDataConvert -Version 3.2.8

Next we go ahead with calling our function for DOCX to PNG:

using System;
using System.Diagnostics;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Api;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Client;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Model;
namespace Example
{
public class ConvertDocumentDocxToPngExample
{
public void main()
{
// Configure API key authorization: Apikey
Configuration.Default.AddApiKey("Apikey", "YOUR_API_KEY");
// Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
// Configuration.Default.AddApiKeyPrefix("Apikey", "Bearer");
var apiInstance = new ConvertDocumentApi();
var inputFile = new System.IO.Stream(); // System.IO.Stream | Input file to perform the operation on.
try
{
// Convert Word DOCX Document to PNG image array
DocxToPngResult result = apiInstance.ConvertDocumentDocxToPng(inputFile);
Debug.WriteLine(result);
}
catch (Exception e)
{
Debug.Print("Exception when calling ConvertDocumentApi.ConvertDocumentDocxToPng: " + e.Message );
}
}
}
}

And that’s all there is to it, really. Simple
