Principles of Design



Explaining Vectors

Next we need to know a little about the difference between Vector images and Bitmap images.

With BITMAP images, like the photographs taken with a digital camera, the image can only be scaled up to a certain size before the individual pixels become visible, and the image starts to lose quality. Vector images can be made as large as you like, as they're not composed of pixels, but are rather ‘instructions’ for drawing the image.

Vector graphics are sometimes called Object Oriented Graphics, because an image is made independently, without affecting the other parts of the image. Individual objects can also be duplicated and resized easily

Vector-based images are less commonly used than pixel-based ones. Instead of being recorded as blocks in a grid, vector images consist of lines, points, and curves. Since they’re made up of a series of mathematical coordinates, they can be blown up to any size and still remain sharp.

They’re chiefly used for graphic illustration as well as graphic and logo design. They’re not suited for detailed, painted or photographic imagery. Photoshop has some vector drawing tools, but Adobe Illustrator is the app designed for creating vector work.
