Java 2D™ supports loading these external image formats into its BufferedImage format using its Image I/O API which is in the javax.imageio package. Image I/O has built-in support for GIF, PNG, JPEG, BMP, and WBMP.

To load an image from a specific file use the following code:

BufferedImage img = null;
try {
    img = ImageIO.read(new File("image.jpg"));
} catch (IOException e) {
   e.printStackTrace()
}

The safest way to convert a regular Image to a BufferedImage is just creating a new BufferedImage and painting the Image on it, like so:

Image original = ...;

BufferedImage b_img = new BufferedImage(original.getWith(), original.getHeight(), BufferedImage.TYPE_4BYTE_ARGB);
// or use any other fitting type

b_img.getGraphics().drawImage(original, 0, 0, null);

This may not be the best way regarding performance, but it is sure to always work.

use ImageIO.read(File) . It returns BufferedImage :

BufferedImage image = ImageIO.read(new File(filename));

Try this, Use class "javax.imageio.ImageIO" like

BufferedImage originalImage = ImageIO.read(new File("c:\\image\\mypic.jpg"));
