AMIRLYX: Vector and Raster Graphics

Vector and Raster Graphics

0 Comments

As for our first assignment, we are asked to identify vector graphics around us, therefore before I starts with it I wanted to clarify the definition of it. Here's something to help you understand;

vector graphics

Vector graphics are created in graphics packages and consist of shapes called objects. It is possible to edit each object separately, for example, change the shape, colour, size and position. Even if an object in a vector graphic is quite large, it doesn't need a lot of computer memory. Therefore the file size of a vector graphic is often very small. Vector graphics are scalable, when you resize them, they do not lose quality like raster graphics.

RASTER GRAPHICS

Pictures found on the Web and photos you import from your digital camera are raster graphics. They are made up of grid of pixels, commonly referred to as a bitmap. The larger the image, the more disk space the image file will take up. Raster graphics are digital images created or captured (for example, by scanning in a photo) as a set of samples of a given space. A raster is a grid of x and y coordinates on a display space. (And for three-dimensional images, a z coordinate.) A raster image file identifies which of these coordinates to illuminate in monochrome or color values. The raster file is sometimes referred to as a bitmap because it contains information that is directly mapped to the display grid.
