How do I convert a TIF to PNG in Java?

Question

Under Java what is the best way to go about converting an TIF file to a PNG?

Simplicity is preferable, but if the simplest way is to use a third party library then I would consider that solution.

Answer 1

First, install JAI. Then install JAI/ImageIO. Then do

public static void main(final String[] args) throws Exception
{
    final BufferedImage tif = ImageIO.read(new File("test.tif"));
    ImageIO.write(tif, "png", new File("test.png"));
}

Answer 2

Use imageMagic java libraries like im4java, their performance and quality is much better then JAI

for example:

import org.im4java.core.ConvertCmd;
import org.im4java.core.IMOperation;

public static void convertTifToPng(File inputImage, File outputImage){
  IMOperation op = new IMOperation();
  op.addImage(); //place holder for input file
  op.addImage(); //place holder for output file

  ConvertCmd convert = new ConvertCmd();
  convert.run(op, new Object[]{inputImage.getAbsolutePath(), outputImage.getAbsolutePath()});
}

maven dependency for im4java is

<dependency>
  <groupId>im4java</groupId>
  <artifactId>im4java</artifactId>
  <version>0.98.0</version>
</dependency>
