Iteration 3 progress report

William Barratt

Plan:

  Goal: Develop a method for steganography using P5 .pgm image files, improving on the code from Iteration 2

  Needs: nothing right now

  Expected Outcome: a command-line program to insert a text message into a P5 PGM

  Success test: checking the modification of the file

  Timeline: completion by end of Second Quarter

Design: use algorithm used in Iteration 2

Coding: Had to use fread to read in the binary data.

Testing: not complete

Note: to the user, this program will operate identically to the program in Iteration 2; the main change is that it reads the more complicated P5 PGMs in addition to P2 files.
