How to rasterize a PDF into an image-based PDF in Java

Rasterizing PDF files just got a whole lot easier. Forget about those hours of coding you were dreading, because today we are going to use an API to cut things down to a handful of minutes.

We will be using Jitpack to compile our library, which will require the following references:

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

And:

<dependencies>
<dependency>
    <groupId>com.github.Cloudmersive</groupId>
    <artifactId>Cloudmersive.APIClient.Java</artifactId>
    <version>v3.34</version>
</dependency>
</dependencies>

Once our library is ready, we can invoke editPdfRasterize and drop in our PDF file.

// Import classes:
//import com.cloudmersive.client.invoker.ApiClient;
//import com.cloudmersive.client.invoker.ApiException;
//import com.cloudmersive.client.invoker.Configuration;
//import com.cloudmersive.client.invoker.auth.*;
//import com.cloudmersive.client.EditPdfApi;
ApiClient defaultClient = Configuration.getDefaultApiClient();
// Configure API key authorization: Apikey
ApiKeyAuth Apikey = (ApiKeyAuth) defaultClient.getAuthentication("Apikey");
Apikey.setApiKey("YOUR API KEY");
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.setApiKeyPrefix("Token");
EditPdfApi apiInstance = new EditPdfApi();
File inputFile = new File("/path/to/file"); // File | Input file to perform the operation on.
try {
byte[] result = apiInstance.editPdfRasterize(inputFile);
System.out.println(result);
} catch (ApiException e) {
System.err.println("Exception when calling EditPdfApi#editPdfRasterize");
e.printStackTrace();
}

Ok, our PDF is now rasterized. Not bad, huh? If you liked this approach, we have a cornucopia of similar functions that run the productivity gamut.
