How do I write JPG or GIF files

I replied to a similar question in the Java programming forum. Here is the URL:

Here are steps to convert Image to BufferedImage,

1. Construct a BufferedImage object

2. Get the graphics context

3. Draw the Image object over this graphics context.

public static BufferedImage convertToBufferedImage(Image img,

int wid, int ht, int type){

BufferedImage bi = new BufferedImage(wid, ht, type);

Graphics2D g2d = bi.createGraphics();

g2d.drawImage(img, 0,0,wid, ht, null);

return bi;

}

The type parameter represents the type of the BufferedImage (such as TYPE_INT_RGB). See the Javadocs for the BufferedImage class.

To write to a GIF file, you may have to use a commercial package.
