Relationship between raster graphics and vector

What is the difference between vector and raster graphics?

relationship between raster graphics and vector

Raster, or bitmap, images are made of pixels; little tiny squares of color or shades of black. Vector images are mathematical calculations from one point to. Bitmap (or raster) images are stored as a series of tiny dots called pixels. Each pixel is actually a very small square that is assigned a color, and then arranged in . Learn the difference between raster images and vector images, and when it is appropriate to use each.

The higher the dpi, the better the resolution. Thus, high resolution images should only be used if your equipment has the capability to display them at high resolution. Better resolution, however, comes at a price.

Just as raster files are significantly larger than comparable vector files, high resolution raster files are significantly larger than low resolution raster files. Overall, as compared to vector graphics, raster graphics are less economical, slower to display and print, less versatile and more unwieldy to work with. Remember though that some images, like photographs, are still best displayed in raster format. Despite its shortcomings, raster format is still the Web standard — within a few years, however, vector graphics will likely surpass raster graphics in both prevalence and popularity.

Unlike pixel-based raster images, vector graphics are based on mathematical formulas that define geometric primitives such as polygons, lines, curves, circles and rectangles.

The Difference Between Vector Graphics and Raster Graphics

Because vector graphics are composed of true geometric primitives, they are best used to represent more structured images, like line art graphics with flat, uniform colors.

Most created images as opposed to natural images meet these specifications, including logos, letterhead, and fonts. Inherently, vector-based graphics are more malleable than raster images — thus, they are much more versatile, flexible and easy to use. The most obvious advantage of vector images over raster graphics is that vector images are quickly and perfectly scalable. There is no upper or lower limit for sizing vector images.

Just as the rules of mathematics apply identically to computations involving two-digit numbers or two-hundred-digit numbers, the formulas that govern the rendering of vector images apply identically to graphics of any size. Further, unlike raster graphics, vector images are not resolution-dependent. Vector images have no fixed intrinsic resolution, rather they display at the resolution capability of whatever output device monitor, printer is rendering them.

Raster graphics are also excellent for catalogs, flyers, postcards, stationery, and other everyday projects. Raster images take more hard disk space than vector format images, even when they appear to look the same. That is because raster files include information about each pixel in the graphic. Compression techniques can mitigate this issue, although if space is a major concern these graphics may present you with a challenge.

Typical raster graphic file formats include. Some advantages of raster graphics include the following: The primary disadvantage of raster graphics is that they are not always usable for creating high-quality printed projects, especially when the desired end product is large-format. Vector graphics A vector graphic is not made up of pixels; instead, it is made up of paths, each with a vector or mathematical formula that controls its shape and color.

These are the vectors. Because the vectors are mathematically defined, vector graphics are scalable and can be blown up to any size without losing any quality or getting any of the fuzzy, pixelated qualities that you see when you zoom in on raster images. For this reason vector graphics are ideal for logos and other projects that need to remain sharp at multiple sizes.

Adobe Illustrator and CorelDraw are the most popular vector graphics editors. Common vector file types include. The principal advantage of vector graphics is that they produce the most precise, clearest designs at any scale.

The main disadvantages are that vector graphics demand professional design software and the ability to use it. Pros and cons of rasters and vectors Raster graphics can reveal a multitude of colors in a single image and allow for more precise color editing.

Vector and Raster: What’s the difference?

They showcase finer nuances in shading and light at higher resolutions. However, raster files, especially high resolution files, are very large.

They also have a limit to their scalability.
