Quarkusproj

Step 1: Create a Quarkus project

You can use the Quarkus Maven archetype to create a new Quarkus project with the following command:

mvn io.quarkus:quarkus-maven-plugin:2.6.3:create \

    -DprojectGroupId=com.example \

    -DprojectArtifactId=image-resizer \

    -DclassName=com.example.ImageResizer \

    -Dextensions="quarkus-amazon-s3"

This will create a Quarkus project with the artifactId "image-resizer" and a Java class called "ImageResizer" in the package "com.example".

Step 2: Add dependencies

Open the pom.xml file of your Quarkus project and add the following dependencies:

<dependency>

    <groupId>io.quarkus</groupId>

    <artifactId>quarkus-amazon-s3</artifactId>

</dependency>

<dependency>

    <groupId>com.drew</groupId>

    <artifactId>metadata-extractor</artifactId>

    <version>2.15.0</version>

</dependency>

<dependency>

    <groupId>javax.media</groupId>

    <artifactId>jai_core</artifactId>

    <version>1.1.3</version>

</dependency>

<dependency>

    <groupId>javax.media</groupId>

    <artifactId>jai_imageio</artifactId>

    <version>1.1</version>

</dependency>

<dependency>

    <groupId>org.imgscalr</groupId>

    <artifactId>imgscalr-lib</artifactId>

    <version>4.2</version>

</dependency>

Step 3: Implement the ImageResizer class

Replace the contents of the "ImageResizer" class with the following code:

package com.example;

import io.quarkus.amazon.s3.runtime.S3Event;

import io.quarkus.runtime.annotations.RegisterForReflection;

import org.imgscalr.Scalr;

import org.jboss.logging.Logger;

import javax.enterprise.context.ApplicationScoped;

import java.awt.image.BufferedImage;

import java.io.ByteArrayInputStream;

import java.io.ByteArrayOutputStream;

import java.io.IOException;

import java.io.InputStream;

@ApplicationScoped

@RegisterForReflection // Required for Quarkus to serialize/deserialize S3 events

public class ImageResizer {

    private static final Logger LOGGER = Logger.getLogger(ImageResizer.class);

    public void resizeImageHandler(S3Event event) {

        LOGGER.info("Received S3 event: " + event.toJson());

        try {

            for (S3Event.NotificationRecord record : event.getRecords()) {

                String bucketName = record.getS3().getBucket().getName();

                String objectKey = record.getS3().getObject().getKey();

                LOGGER.info("Processing object: " + objectKey + " in bucket: " + bucketName);

                resizeImage(bucketName, objectKey);

            }

        } catch (IOException e) {

            LOGGER.error("Error processing S3 event: " + e.getMessage(), e);

        }

    }

    private void resizeImage(String bucketName, String objectKey) throws IOException {

        // Load the original image from S3

        InputStream input = S3Client.getInstance().getObject(bucketName, objectKey);

        BufferedImage image = ImageIO.read(input);

        // Get the desired percentage for resizing

        int percentage = 50; // Change this to the desired

maven add extension 

mvn quarkus:add-extension -Dextensions="quarkus-amazon-sqs"
