Vector graphics, on the other hand, are not composed of points, but of primary graphic elements such as lines, circles and curves. These are called vectors, which are defined by mathematical parameters (coordinates) such as the start point, end point, radius, side length, line thickness, color, and fill pattern. The most modern vector design programs are even capable of reproducing color transitions and transparencies. These objects are not defined as a pixel alignment, but logically based on their qualities . To define a simple circle, for example, only the midpoint position and radius are required, as well as the color and thickness of the line, to be able to render it at any size.
And this is precisely the great advantage of vector images compared to bitmaps: it is an image that can be defined based on its qualities, regardless of its pixel density, it can be scaled without loss of quality , since the parameters they are recalculated based on the final size. On the other hand, if, for example, you want to scale a circle made of pixels, from a certain size you will begin to see the points that compose it due to its intrinsic lack of flexibility ( aliasing or? Step? Effect ). Hence, this type of distorted images are known colloquially as? pixelated images ?..
Regarding the size of these images and the storage space they require, the size of vector graphics has no effect on their weight, since it depends on the number of saved parameters, while bitmaps, in which larger images also need more pixels, they weigh more.
Since the display media (screens, printing) can only reproduce the images as raster graphics, vectorized images have to be transformed into bitmap graphics (rasterization) before being displayed. Depending on the complexity of the object, this is a preliminary step that requires more or less time and power from the team.
