How to emboss an image in Java

Embossing an image can be a really nice touch, and makes an excellent addition to any photo app or website. Getting this effect to work can take a little doing if you approach it in the traditional way. Today, however, we will be doing things a little differently, which will allow us to finish in just a few minutes. Let’s get started!

First off, we need to add two references for Jitpack in pom.xml:

Repository

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

Dependency

<dependencies>
<dependency>
    <groupId>com.github.Cloudmersive</groupId>
    <artifactId>Cloudmersive.APIClient.Java</artifactId>
    <version>v2.75</version>
</dependency>
</dependencies>

Now we are ready to call filterEmboss and define our effect radius and sigma:

// 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.FilterApi;
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");
FilterApi apiInstance = new FilterApi();
Integer radius = 56; // Integer | Radius in pixels of the emboss operation; a larger radius will produce a greater effect
Integer sigma = 56; // Integer | Sigma, or variance, of the emboss operation
File imageFile = new File("/path/to/file"); // File | Image file to perform the operation on.  Common file formats such as PNG, JPEG are supported.
try {
byte[] result = apiInstance.filterEmboss(radius, sigma, imageFile);
System.out.println(result);
} catch (ApiException e) {
System.err.println("Exception when calling FilterApi#filterEmboss");
e.printStackTrace();
}

And… that’s it! No seriously, we are done. Eager to see the results? Let’s test it on this image:

Now let’s add our effect with a radius of 1 and sigma of 2:
