This small pieces of code used to demo some features or techniques and
In my post I illustrate the blending modes using Netpbm format which is
easy and not compressed image format comes in both binary and ASCII
variations and It's 8bit (1 byte per color channel).

If you know blending modes in GIMP you can see the pictures and
understand it.

Will those are small examples and I'm libreal in writing them and I do
that so I can declare them as global variables (Although I forget
to make them static even that is not important) and not care about
including them as parameters to functions also the memory are
dynamically allocated so because I load pictures in the commandline.

Stack arrays are limited and passing them to function will make lose it
size information with sizeof (even tho I can store in other var).

Preprocessor functions are awesome and they can improve performance (and
sometimes make debugging harder).

If you have any suggestion or comment about that send me private message
or in comment section of the post.
