resizing images on the fly

Intro:

After determining where the files are and how to move them into another folder as I showed in my previous post Howto create a set of files on the fly, It is fun to resize the files which are images in this case (makes it easier).

The problem:

We have a set of images, which might change and dont want to resize them by hand everytime.

The solution:

The solution lies hidden in Java as many times. The following example shows howto resize:

private void createIcons(String path){

    int width=100;

    int height = 100;

    File imageInput = File(path);

   ImageIcon imageIcon = new ImageIcon(path);

   BufferedImage imageResize =

  new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);

  Graphics2D graphics2d = imageResize.createGraphics();

  graphics2d.addRenderingHints(

   new RenderingHints(RenderingHints.KEY_RENDERING,RenderingHints.VALUE_RENDER_QUALITY));

   graphics2d.drawImage(imageIcon.getImage(), 0, 0, height, width,

   null);

   String iconName = path.replaceAll(

   IMAGES, ICONS);

   try {

      ImageIO.write(imageResize,

      "png", new File(iconName));

    }

    catch (IOException ioe) {

      LOGGER.error("The image " + iconName + " could not be saved!");

    }

}

 In my previous post I had a line "String filePath =path.replace(IMAGES, ICONS); " all you have to do is to replace that line with:  "createIcons(image.getAbsolutePath());" and you be on your way with a full subset of folders and resized images. The only kind of images I had it never working with was BMP.
