Create a Thumbnail

What does it do?

Create a copy of the image with the specified dimensions. This operation uses a scaling routine designed to produce best output when the specified dimensions are smaller than the original.

Scale a BufferedImage in Java

ImageProcessingOperations operations = new ImageProcessingOperations();

// You can chain several operations here such as scale, blur, etc
operations.thumbnail(64, 64); 
// 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-thumbnail-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);
