Jump to PostI don't if this is correct but what I did once, was to read the file line by line(like you read any other text file). You will get numbers. These numbers represent the RGB values. They are from 0 - 16777216 (256*256*256).

Java has an api for working with images. There is no need to read raw file values.
Take a look at some of the examples here:

Specifically you will probably want to work with a BufferedImage:
