Vector graphics are one of the ways to represent graphic information in computer systems, which is the most modern in comparison with a raster image.

Step 1
The principles of constructing an image by means of vector graphics allow you to depict objects through the use of any elementary geometric shapes. These shapes can be points, lines, splines, and polygons. This means that a graphic picture built on the principles of vector graphics is a set of mathematical functions, which is completely opposite to raster graphics, where an image consists of a set of points (pixels) that form a matrix.
Step 2
In computer systems, both vector images and raster images are used. Therefore, to convert one format to another, special converters are used (both software and hardware based on the capabilities of the video card).
Step 3
The principle of constructing simple images in vector format, for example, a circle, is interesting. From a mathematical point of view, to create a circle, you only need to know the location of the center of the circle, the value of the radius, as well as two colors: the fill of the shape and the outline. Information about the thickness of the circle outline is also needed. These parameters are used when generating images in vector form.
Step 4
Vector graphics have distinct advantages over raster graphics. The information required to construct a vector image does not depend on its size. That is, it does not matter what size the circle is, the main thing is to know the value of the radius. This allows you to describe an object of any scale using a file of the minimum size.
Step 5
Another important quality of a vector image, because of which it is increasingly preferred, is the independence of the quality from such manipulations as scaling, rotating, moving, etc. Due to this, it becomes possible to work with graphics more boldly, without thinking about the deterioration in quality with a particular procedure.
Step 6
However, the vector representation also has its drawbacks. For example, not every object can be easily represented in vector format. The more complex the object, the more curves have to be used, which means that more and more memory is required to store such an image, as well as to outline it.
Step 7
It is also worth noting that there is no full-fledged raster-to-vector conversion. Tracing does not provide full preservation of image quality, and also requires significant processing power.
