Hello,
I am trying to create and Image and diplay it on an HTML page
without ever writing it to disk.
This code currently giveas a broken image link :-( Although if I
output to a file the image displays fine ????)

public class TestGif{
private int LEFT_ALIGN = 12;
private String BASE_IMAGE = "x.gif";
public String getImage(){
String count = "0";
Image img = new ImageIcon(BASE_IMAGE).getImage();
BufferedImage bi = new BufferedImage( img.getWidth(null),
img.getHeight(null),
BufferedImage.TYPE_INT_RGB);
Graphics2D big = bi.createGraphics();
big.drawImage(img, 0, 0, null);
// big.setColor(Color.black);
// big.setFont(new Font("Arial",Font.BOLD,11));
ByteArrayOutputStream bos = new ByteArrayOutputStream();
try{
Acme.JPM.Encoders.GifEncoder encoder = new
Acme.JPM.Encoders.GifEncoder(bi,bos);
encoder.encode();
bos.close();
}catch(IOException e){ e.printStackTrace(); }
return new String(bos.toByteArray());
}
