Generate Grayscale Image in Java

We are going to discuss the deatils and steps on how to generate Grayscale Image using Aspose.Imaging Cloud SDK for Java. With simple steps, we are going to load the source/input raster image from local drive, convert to Grayscale picture using CreateGrayscaledImage API. After the conversion, the resultant image is stored in Cloud Storage. For complete details, please visit Convert Image into Black and White.

// Get ClientID and ClientSecret from https://dashboard.aspose.cloud/
String clientId = "7ef10407-c1b7-43bd-9603-5ea9c6db83cd";
String clientSecret = "ba7cc4dc0c0478d7b508dd8ffa029845";

// create Imaging object
ImagingApi imageApi = new ImagingApi(clientSecret, clientId);

// load file from local drive
File f = new File("PinClipart.png");

// read the content of PNG image to byte array
byte[] bytes = Files.readAllBytes(f.toPath());
					    
// create Grayscale conversion request where we specify the name of resultant file
CreateGrayscaledImageRequest request = new CreateGrayscaledImageRequest(bytes,"grayscale.jpg",null);

// Convert Image into Black and White
imageApi.createGrayscaledImage(request);
