Also because vector graphics are basically a A bunch of mathematical values that need to be calculated and rendered in real time to be displayed on the screen. Well, the answer is not all images best represented by a vector graphics, complex images like photograph, due to the nature of it is best represented in raster images. You might be wondering why now, why not we just use a vector for all of our graphics. This is something that you cannot do in purely raster images. For example, when we draw a circle like this in Illustrator, we can always select it and tweak the shape, or recolor it as we like, the shape is still alive and editable. Working in vector also gives us more flexibility.īecause we can always go back and change things around. We can resize or scale vector graphics to any size we want without the risk of losing any graphical information. Notice when we zoomed in to as far as we can go won't see any pixels. Vector Graphics are also resolution independent. These points and curves and color fields are stored as mathematical values, not as pixel great data like raster images do so as the result and generally speaking, vector images are smaller in file size than the raster image version. Basically, the higher the resolution, the bigger the file size, vector graphics or images made of points, curves connecting those points and color fields inside the area formed by those curves. high resolution images will have finer detail because more color information can be contained by the image, but the file size will be bigger. What do I mean by that? If we have an image of 100 by 600 pixels resolution for example, it means it has 100 columns and 600 throes of total pixels. Because raster images are made of pixels, they are resolution dependent. The word pixel is actually came from the abbreviation of picture element.Įach of the pixel has only one color applied to it.

But notice when we zoom in, we start to see the reality that this image is actually made of these small squares. When you see images like this, for example, it looks nice and smooth. First, let's talk about raster, raster graphic, or images made up of numerous small squares.

In computer graphic world, there are two types of graphic, raster, and vector.
