Resize to Fit

What does it do?

The resize to Fit operation will rescale the image so that it fit into the defined pixel rectangle as closely as possible. Aspect ratio is preserved, so the image is not stretched and will end up being either the width or height specified but not both unless the aspect ratio of the image is the same as the specified new size.

Resize a BufferedImage in Java

ImageProcessingOperations operations = new ImageProcessingOperations();

// You can chain several operations here such as scale, blur, etc
operations.resizeToFit(100, 100); // make image fit into a box 100x100 pixels preserving aspect ratio
        
// 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-resizedToFit-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);
