Hi,
Does anybody know how to make the png file smaller? I used the following code to convert a jpg file to a png file but the problem is that the png file turned out to be much bigger than the origianl jpg file. Any idea of this? Thanks a lot.
-------------------
try{
File f = new File("pic1.jpg");
BufferedImage bi = ImageIO.read(f);
File outfile = new File("pic2.png");
ImageIO.write(bi, "png", outfile);
System.out.println("Converting is successful");
}catch(IOException e){
System.out.println("Converting is failed");
}
--------------------
