Pixels, Images and Image Files

Summary

In this chapter, we have seen how images are stored on the computer. Any kind of graphics, whether a visually realistic simulation of the environment or a simple 2D drawing, is eventually saved as a 2D raster image on the computer. Storing and viewing these images is just the tip of the iceberg: we can use these images in our own projects and even modify them to achieve desired results and special effects. The techniques we have discussed here are used extensively in production suites for image processing and gaming. They form the basis for the more complicated image enhancements and effects used in the industry. In the next chapter, we shall put together all our current working knowledge to design and develop a 2D game.
