Java: Convert image to png format

• Make sure you have JAI & ImageIO plugins installed. Recommend to use standlone/independent jai-imageio-core from github.
• The example code:

import java.awt.image.BufferedImage;
import java.io.File;
import javax.imageio.ImageIO;

public static void main(String[] args) {

  ImageIO.scanForPlugins();

  // read a tiff image
  BufferedImage bufferedImage = ImageIO.read(new File("c:/tmp/1.tif"));

  // write back to another file in png format
  ImageIO.write(bufferedImage, "png", new File("c:/tmp/1.png"));

}
