combing red green and blue files to make a .ppm file in a C programme

Question

i currently have 3 files, a red, a green and blue component file(s) and i need to code a program that will combine these three files into a single readable ppm file. how/whats the best route for me to take for this? thanks Sam

Answer 1

You mean, like this: rgb3toppm.c?

If you're doing this as an exercise, you can look at the source code for that utility. If you just need the utility, you'll probably find rgb3toppm in your netpbm distribution.
