Using binarize... Getting Tiff Image in Black Background..

Question

Hi,
Basically my subject summarizes my problem, but I am trying to write some text to a blank JPEG file and then create a Tiff file from that JPEG...
But When i use the binarize i am getting the image as black background and the resolution is not that great...
I am using binarize, because i need to use TIFFEncodeParam.COMPRESSION_GROUP4 but i was getting bi-level error, that is why i am using binarize to create a GROUP4 with black and white color to minimize the file size...
I am posting the source code, i would appreciate someone can take a look at this code and figure out why i am getting black background...in the tiff file...
Any help will be greatly appreciated...
Thanks in advance...

try this:
BufferedImage bi = new BufferedImage(1728,500,BufferedImage.TYPE_BYTE_BINARY);
Graphics2D big = bi.createGraphics();
Graphics2D g2 = bi.createGraphics();
big.setFont(new Font("Dialog", Font.PLAIN, 20));
big.setColor(Color.WHITE);
big.fillRect(0,0,1728,500);
big.setColor(Color.BLACK);
big.drawString("Data/Time Created:" + new java.util.Date(), 80, 210);
big.drawString("POLICY NUMBER: 1711215 NAME OF CALLER: BENEFICIARY", 80, 230);
big.drawString("Requested: Loan Request XXXXXXXXXXXXXXXXXXXXXXXXXXXXX Current Loan Value: $0.00", 80, 270);
g2.drawImage(bi, 0, 0, null);
