Color values are 0-255

Look at getRGB in BufferedImage API:

http://java.sun.com/j2se/1.5.0/docs/api/java/awt/image/BufferedImage.html

And also at getSample in Raster API, you get the raster using BufferedImage.getData()

http://java.sun.com/j2se/1.5.0/docs/api/java/awt/image/Raster.html

Are you working with grayscale image or RGB?

If you work with grayscale images it would be easier to use image.getData().getSample(x, y, 0) it will return the pixel value for (x,y) coordinate.
