# Vector Image

A vector-based image is a type of digital graphic that is composed of mathematical equations rather than a grid of pixels. It is created using geometric shapes, lines, and curves that are defined by their position, size, and direction. Unlike raster images, which are made up of a fixed number of pixels and can become pixelated when scaled up, vector images can be scaled infinitely without any loss of quality.

In a vector image, each element is represented as a separate object or entity, known as a vector. These vectors are stored as mathematical formulas that describe their characteristics. For example, a straight line may be represented by a starting point, an ending point, and the equation for the line connecting them. This mathematical representation allows vector images to be easily manipulated and edited.

A key advantages of vector-based images is their scalability. Since the shapes are defined by mathematical equations, they can be resized without any loss of detail or resolution. Whether you increase or decrease the size of a vector image, the curves and lines remain smooth, resulting in a crisp and clear image at any scale. This makes vector graphics ideal for logos, icons, and illustrations that need to be used across various sizes and media types.

Another important characteristic of vector images is their editability. The mathematical formulas that define the elements of a vector image can be modified, allowing for easy editing and manipulation. You can change the color, size, shape, or position of individual elements without affecting the rest of the image. This flexibility makes it possible to make precise adjustments and revisions to vector graphics, saving time and effort in the design process.

Also, vector-based images have a relatively smaller file size compared to raster images. Since the image is stored as a series of mathematical equations rather than a grid of pixels, the file size is determined by the complexity and number of objects rather than the resolution. This makes vector images ideal for use on websites and in digital media where file size and loading times are important factors.

### Summary

Vector-based images are digital graphics created using mathematical formulas to define shapes, lines, and curves. They offer scalability, allowing for resizing without loss of quality, and editability, enabling easy modification of individual elements. Vector graphics have smaller file sizes and are resolution-independent, making them versatile for various applications such as logos, icons, and illustrations.
