Vector backgrounds are images made up of lines and geometric shapes, created using mathematical equations. They can be easily edited and have advantages over raster images, such as the ability to be enlarged without losing quality and smaller file size. However, they are not suitable for all types of images and require a special image editing application. Vector images are commonly used for maps, architectural plans, and logos.
A vector background is a type of image used as a website background or as a computer desktop background. Instead of the dots or pixels that make up raster images, vector images are made up of lines and geometric shapes, and mathematical equations are used to create the image. Each shape in the image is considered an object that can easily be changed to have a different color or size. To create or edit a vector background, you need to use one of the special image editing applications available for multiple platforms. Vector backgrounds have both advantages and disadvantages over raster images and are not the best format for all types of images.
Compared to a vector background image that uses mathematical formulas along with lines, curves, and shapes, a raster image uses square pixels that become less clear when the image is magnified in any way. Objects in vector images have two elements that determine how the image appears. The length of each line is how large it is, and the direction in which the line is placed determines the orientation.
Vector background images have an advantage over raster graphics in that they can be enlarged without losing image quality. Although raster graphics become distorted and noticeably lose quality when enlarged, vector images retain their appearance and are much more flexible with resolution. Another advantage is that vector backgrounds have a smaller file size than many other image formats. This makes them suitable for website backgrounds, because they load better for users with slower Internet connections.
Some disadvantages of vector graphics are that they are not the best choice for some types of images and can take longer to create. While they are suitable for illustrated backgrounds that contain complex shapes, they are not useful for photographic images. Also, vector graphics don’t support some advanced image editing techniques, including lighting effects, complex color shifts, and blurs. A special image editing application is required to edit vector images, so they are not universal like raster images and may display differently between different programs.
Vector images are commonly used for maps, architectural plans, and various other types of two-dimensional (2D) and three-dimensional (3D) images. Raster images, on the other hand, include images taken by cameras, imported from scanners, or made with many traditional image editing programs. In addition to vector backgrounds, vector images are often used for company logos, as they can be scaled for use on many types of signage, banners, and promotional materials.
