How to convert a PowerPoint PPTX to a PNG Array in C# .NET Framework

Sometimes PPTX format can be quite inconvenient, leading to all sorts of problems with compatibility. To solve this problem once and for all, we will be exploring a solution today that will allow us to convert PPTX files into arrays of PNG images. This will take just a handful of minutes, mostly just waiting for our package to install and testing it.

So let’s grab that package first:

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

And next we will call our function for converting between the formats:

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 ConvertDocumentPptxToPngExample
{
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 PowerPoint PPTX to PNG image array
PptxToPngResult result = apiInstance.ConvertDocumentPptxToPng(inputFile);
Debug.WriteLine(result);
}
catch (Exception e)
{
Debug.Print("Exception when calling ConvertDocumentApi.ConvertDocumentPptxToPng: " + e.Message );
}
}
}
}

And that’s really all there is to it!
