How to Convert Keynote KEY to PNG in C# .Net Framework

By the end of this tutorial, all of the pain and suffering that Mac’s Keynote format was causing you will be a thing of the past. And that will be in a matter of mere minutes. How can we accomplish this so quickly? We are going to employ a Cloudmersive API that can seamlessly cut your KEY files into individual slides and convert them into images.

The first step on our process is to grab the Cloudmersive Convert API client:

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

And next in line is our function call. The details for this are laid out in this example 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 ConvertDocumentKeynoteToPngExample
{
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 Keynote Presentation (KEY) to PNG image array
KeynoteToPngResult result = apiInstance.ConvertDocumentKeynoteToPng(inputFile);
Debug.WriteLine(result);
}
catch (Exception e)
{
Debug.Print("Exception when calling ConvertDocumentApi.ConvertDocumentKeynoteToPng: " + e.Message );
}
}
}
}

Done.
