How to convert an HTML Document to PNG Array in C# .NET Framework

Sometimes it’s just much more convenient to have documents in image form. Unfortunately, this process is often quite difficult, as you need to first render the HTML, rasterize that into an image, then split the image into individual pages. This can take all day if you’re not careful. So instead of that, how about I show you a nice quick shortcut that will take care of your HTML conversion needs almost instantly.

First we install our client:

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

Next we can go ahead and call this function here:

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 ConvertDocumentHtmlToPngExample
{
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 HTML document file to PNG image array
PdfToPngResult result = apiInstance.ConvertDocumentHtmlToPng(inputFile);
Debug.WriteLine(result);
}
catch (Exception e)
{
Debug.Print("Exception when calling ConvertDocumentApi.ConvertDocumentHtmlToPng: " + e.Message );
}
}
}
}

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