Kernel Operation
What does it do?
Kernel operation can be used to set 3 x 3 kernel to apply to image (null is converted to identity).
Apply a 3*3 kernel to a BufferedImage in Java
ImageProcessingOperations operations = new ImageProcessingOperations();
// You can chain several operations here such as scale, blur, etc
operations.kernel(new float[]{0.0f, 0.0f, 0.0f, 0.0f, 1.0f, 0.0f, 0.0f, 0.0f, 0.0f});
// Apply the operations to a BufferedImage
BufferedImage modifiedImage = operations.apply(BufferedImage originalImage);

Additional Code Examples
Process and convert between image formats using the following code examples:
Using File
File inputFile = new File("path/to/file");
File outputFile = new File("path/to/output-kernelApplied-file");
JDeli.convert(inputFile, outputFile, operations);
Using InputStream and OutputSteam
final InputStream inputStream = new FileInputStream(inputFile);
final OutputStream outputStream = new FileOutputStream(outputFile);
final String outputFormat = "format"; // format of the output file eg. png, jpeg,...;
JDeli.convert(inputStream, outputStream, outputFormat, operations);
Using byte[]
byte[] inputData = Files.readAllBytes(Paths.get("/path/to/file"));
final String outputFormat = "format"; // format of the output file eg. png, jpeg,...;
byte[] outputData = JDeli.convert(inputData, outputFormat, operations);
