Hi,
I'm trying to generate a black and whit barcode graphic image in a servlet.
I'm using the com.sun.image.codec.jpeg.JPEGImageEncoder.
This works fine but I get pretty good barcodes.
However if I look very closely at the image there are a number of grey
dots in areas that should be white.
Should I be looking for another type of encoder?
Any help with this would be really appreciated.
regards
Graham
.. here's the guts of the code
protected void doGet(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, java.io.IOException {
// Set the correct content type
response.setContentType("image/jpeg");
// get the output stream
ServletOutputStream out = response.getOutputStream();
// Create a new image object
java.awt.image.BufferedImage image = new
BufferedImage(WIDTH,HEIGHT,BufferedImage.TYPE_INT_RGB);
// Get a Graphics object we can draw into
java.awt.Graphics g = image.getGraphics();
////
// Draw the barcode using the Graphics object
////
// Create the encoder on our output stream
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
// pump out our image
encoder.encode(image);
// we're done
out.close();
}
