The picture is automatically converted to icon

[lhDream]

Hi @fvarrui .
Are you considering adding the function of automatically converting pictures to icons?

I can provide the following sample:

import net.ifok.image.image4j.codec.ico.ICOEncoder;

import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class Demo {

    public static void main(String[] args) throws IOException {
        BufferedImage bufferedImage = ImageIO.read(new File("d://logo.png"));
        if(bufferedImage == null){
            System.out.println("File not find");
        }
        List<BufferedImage> icons = new ArrayList<>();
        icons.add(getScaledInstance(bufferedImage, 16, 16));
        icons.add(getScaledInstance(bufferedImage, 32, 32));
        icons.add(getScaledInstance(bufferedImage, 64, 64));
        icons.add(getScaledInstance(bufferedImage, 128, 128));
        ICOEncoder.write(icons,new File("d://logo.ico"));
    }

    public static BufferedImage getScaledInstance(BufferedImage bufferedImage,int toWidth,int toHeight){
        Image scaledInstance = bufferedImage.getScaledInstance(toWidth, toHeight, Image.SCALE_SMOOTH);
        BufferedImage newBufferedImage = new BufferedImage(toWidth,
                toHeight, BufferedImage.TYPE_INT_RGB);
        newBufferedImage.createGraphics().drawImage(scaledInstance, 0, 0, Color.WHITE, null);
        return newBufferedImage;
    }

}

Hi @lhDream! Thanks for your proposal. Maybe can we do that JavaPackager looks for a PNG file and convert it in an ICO file if it can't find this last one?

Hi @fvarrui !
Yes. Or automatically convert when configured like this.

<icoFile>yourPath/logo.png</icoFile>
