    Writing Compressed Image Files

    Hi, first time poster here.

    I am making an image compressor that just takes in Bitmaps and produces a compressed output however I'm having a big problem, I cannot find a way to write values lower than 8-Bit Integers to files.

    is there a way to do this? Cause it's kinda pointless oututting 1011 as 00001011!

    Thanks

    Not that I'm aware. A byte is the smallest unit you can write to a file at a time.

    There are two ways to go about this. One way is to use the C++ STL bitset class, which allows you to manipulate individual bits (set, clear, etc). To use this, include <bitset>.

    A second way is to use the shift operators. That way you can take say 4 bits, shift them to the left, then use the or (|) operator to add 4 more.
