What is Vector Graphics ?

Vector graphics are not made with pixels, they are made with vectors. Vectors are defined directions used to draw graphics on screen using mathematical equations, as compared to raster images that use a grid of mapped pixels. Instead of placing pixels into a grid to create a circle, vectors based programs draw a circle from an equation. The advantage of using equations instead of pixels to draw shapes is that there is no "resolution" involved. Because the vectors based drawing program creates a circle based on an equation, a circle drawn with a 10 inch radius is no different than a circle drawn with 10,000 inch radius (one just has bigger number in the equation than the other). VectorGraphics can be resized to any size (bigger or smaller) without becoming "pixelated" or without losing resolution, unlike raster images than can only be re-sized down without losing clarity. Vector graphics are the best choice for line art (Example: logos, and text) because the outlines of these shapes are always sharp, and cleanly defined. Fonts are vectors based. For each character of a font there is an equation defining it's shape. In general, text should be made using fonts, and not raster images. I do not recommend laying out the text of your design in Adobe: Photoshop. Photoshop does handle nice clean vectors based fonts, however any fonts used in your file will have to be "rasterized" (or "rendered") and converted from vectors form to raster form. I would recommend Adobe: Illustrator for creating vectors text. Raster text is not as sharp as vector text. |
