Hi,
You can get every pixel and store into a file and also retrieve and use it as per your choice by using graphic commands in C language.Commands like getpixel(),sertpixel(),.. are there to code your requirment.These commands take pixel from worldview an dmap it to viewport and commands are there to do viceversa also.

To have a good reading of these commands and code your requirment have a reading of the book

Graphics in C - By Vijay Mukhi's - BPB Publications
Also for C++ you have C++ and Graphics - The Future of C - Vijay Mukhi's - BPB Publications

This gives a detailed explanation of syntax of all graphic commands in C
