A second project for the PUT Computer Architecture with Low-Level Programming - parsing BMP files
Task - write a C program to parse BMP files; Requirements:
- (3.0) program should accept one command line parameter in the format
./program PATH-TO-BMP-FILE, and print out parsed values from the file header - (3.5) additionally, program must print out parsed values from the info header
- (4.0) program prints out a histogram of RGB colors
- (4.5) program handles case when started with two command line parameters in the format
./program PATH-TO-INPUT-BMP-FILE PATH-TO-OUTPUT-BMP-FILE; the output BMP file should have exactly the same values as the input BMP, but the pixel array should be modified to make the image greyscale using the simplest formula gray = (r + g + b) / 3 - (5.0) program uses steganography to hide a text inside BMP pixel array, input in the format
./program PATH-TO-INPUT-BMP PATH-TO-ENCODED-BMP "text to be hidden"; the program should also ask the user if they want the message to be decoded from the output
