//package com.java2s;

import java.awt.image.BufferedImage;

public class Main {
    public static BufferedImage scaleImage(BufferedImage originalImage,
            int multiplier) {
        int imageWidth = originalImage.getWidth();
        int imageHeight = originalImage.getHeight();
        BufferedImage scaledImage = new BufferedImage(imageWidth
                * multiplier, imageHeight * multiplier,
                BufferedImage.TYPE_INT_ARGB);

                        / (double) scaledImage.getWidth()
                        * originalImage.getWidth()).intValue();
