Resize to Height

What does it do?

The resize to Height operation will rescale the image so that it is a set number of pixels high.

Resize a BufferedImage in Java

ImageProcessingOperations operations = new ImageProcessingOperations();

// You can chain several operations here such as scale, blur, etc
operations.resizeToHeight(100); // make image 100 pixels high 
        
// 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-resizedToHeight-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);

Why JDeli?

  • Support image formats such as AVIF, HEIC and JPEG XL (AVIF soon) that are not supported in Java.
  • Process images up to 3x faster than ImageIO and alternative Java image libraries.
  • Prevent JVM crashes caused by native code in other image libraries such as ImageIO.
  • Handle JPEG, PNG, TIFF image file formats fully in Java.
  • Keep your Image files secure as JDeli makes no calls to any external system or third party library.
