Vector graphics are a graphical representation method based on mathematical formulas. They use straight lines, curves, points, polygons and other geometric primitives to describe images. In contrast, bitmap images use arrays of pixels. To represent images, it can be infinitely scaled without distortion, has a small file size, supports editing and manipulation, is suitable for various types of image creation and design, is widely used in the design field and printing industry, and can provide high quality and Flexible imaging solutions.

Vector Graphics is a graphic representation method based on mathematical formula description. It uses geometric primitives such as straight lines, curves, points, and polygons to describe images. In contrast, a Bitmap image uses an array of pixels to represent an image.

Vector graphics describe images by determining the shape, position, color and line attributes of graphics. It uses mathematical formulas to describe graphics, so it can be infinitely scaled without distortion. This means that vector graphics retain crisp details and smooth curves, whether on a small icon or a large advertising poster.

In contrast, bitmap images use an array of pixels to represent the image, so aliasing and distortion will occur when scaling. When we enlarge a bitmap image, each pixel is stretched, causing the image to become blurry. Vector graphics don't have this problem because they are based on mathematical formulas and can be resized as needed.

Another advantage of vector graphics is their smaller file size. Because a vector image only needs to save the mathematical formula and attribute information of the graphic, its file size is usually much smaller than a bitmap image. This makes vector graphics more efficient when transmitted and stored over the network.

Vector graphics can create various types of images, including icons, logos, illustrations, maps, charts, and more. It is widely used in the design field and printing industry because of its ability to maintain the quality and clarity of images and allow for easy modification and editing.

Vector graphics also have some other features, such as the ability to use graphics processing software to edit and manipulate images. We can modify a vector image by adding, removing, or changing graphic elements without redrawing the entire image. This makes vector graphics more flexible and efficient in the design process.

In addition, vector graphics also support graphic fill and gradient effects, which can achieve more diverse and rich image effects. At the same time, vector graphics can be easily converted into bitmap images for display on web pages or for use in other applications.

To sum up, vector graphics is a graphic representation method based on mathematical formula description. It can be infinitely scaled without distortion, has a small file size, supports editing and manipulation, and is suitable for various types of image creation. and design. It is widely used in the design field and printing industry to provide high quality and flexible image solutions.
