Abstrakt: Instructors teaching beginning programming classes are often interested in exercises that involve processing photographs (i.e., files stored as .jpeg). They may wish to offer activities such as color inversion, the color manipulation effects archived with pixel thresholding, or steganography, all of which Stevenson et al. [4] assert are sought by students. However, instructors may not find textual support for these topics since widely used introductory textbooks do not illustrate the needed techniques, and the professional Java literature obscures these straightforward operations in elaborate discussions. This paper presents the code to make image processing accessible through fragments used to hide a text message in a read-in JPEG file, store the image as a PGN file, and extract the message from the stored image.
