If you are using Java 2D, you can create a JPEG image by using the
com.sun.image.codec.jpeg package. The code below creates a JPEG image and
saves it to a file.
public void save(BufferedImage destImage, String filename) {
try {
ByteArrayOutputStream boutstream = new ByteArrayOutputStream();
JPEGImageEncoder enc = JPEGCodec.createJPEGEncoder(boutstream);
enc.encode(destImage);
FileOutputStream fimage = new FileOutputStream(new File(filename));
boutstream.writeTo(fimage);
fimage.close();
} catch (Exception e) { }
The code snippet below shows how to crerate a BufferedImage:
BufferedImage bi = new BufferedImage((int)imWid,
(int)(imHt),
BufferedImage.TYPE_INT_RGB);
Graphics2D g2d = bi.createGraphics();
g2d.drawImage(img, dispTx,this);
img : Your image object.
dispTx: The Affine Transform.
You can use other drawImage()methods for drawing images.
Once the image is drawn, you can save it using the save() method.
