On the other hand, vector images are composed of mathematical paths, or lines, that connect to make shapes. When you zoom in on a vector image, you’ll see the individual paths that make up the image. The main difference between raster and vector files is how they store information.
- When you take a picture with a phone or camera, the image is recorded as pixel data.
- If you look closely at a vector image you will see control points with curves between them, almost like a child’s connect the dots game.
- In this blog post, we’ll delve into the fundamental raster vs vector graphics, explore their advantages and disadvantages, and help you determine which format best suits your specific needs.
- You can identify whether an image is raster-based or vector-based by zooming in on it really closely.
- If you are on a budget choose Raster graphics as they cost less.
It comes without further saying that you will have the appropriate software in hand. If you’re one to surf the web, chances are that you’ve seen and used tons of raster images before. Whenever you take a photo with your phone, or take a screenshot on your computer, you’re creating a raster image. All digital images can be classified as either raster or vector.
Looking for Design Bundles or Cartoon Characters?
Vector images don’t lose their sharpness and clarity, no matter to what extend or how many times you change their size. Vectors’ scalability make them ideal for design work consisting of logos and icons. Both logos and icons require immense detail and many size options, usually depending on their application. For example, you might use a logo on something as small as a business card or something as large as a billboard. Vectors are ideal for both large and small format prints, because rasterized designs will lose quality when resized.
If you’re working primarily within a specific design software like Illustrator or CorelDRAW, using their native formats (AI and CDR) ensures full editing capabilities. Overall, whenever you need an image format that excels at capturing intricate details, realistic colors, and photographic quality, raster images are the way to go. The fundamental strategy underlying the raster data model is the tessellation of a plane, into a two-dimensional array of squares, each called a cell or pixel (from “picture element”). The size of each square pixel, known as the resolution or support, is constant across the grid. Raster or gridded data may be the result of a gridding procedure. If that technical explanation didn’t make much sense to you, think of it this way.
Pros and cons of rasters and vectors
Meanwhile, no matter how much you zoom in on the panther on the right, you will always see smooth lines. Another handy design resource is Shutterstock Create, a free raster-based image editor that lets users create and edit high-quality images on any device. Adobe Photoshop is one of the most popular raster-based editors available and has been used to edit photographs, create graphic designs, and illustrate. A vector image’s formulaic makeup keeps file sizes to a minimum in comparison to its raster counterparts. This comes in handy when there are restrictions to file sizes or image storage. While a vector image file has many advantages, there are compatibility issues when shared.
During the 1970s and 1980s, pen plotters, using Vector graphics, were common for creating precise drawings, especially on large format paper. However, since then almost all printers create the printed image as a raster grid, including both laser and inkjet printers. When the source information is vector, rendering specifications and software such as PostScript are used to create the raster image. Usually, raster images can’t be scaled any larger than their original width and height.
What are the differences between vector graphics and raster graphics?
Vector images represent mathematical calculations involving a point or place that form outlines or shapes(maintain quality.). Whenever one zooms over vector pictures, they look the same (infinitely scalable). When enlargement of images is performed without change of pixels, it looks blurry. If you add more pixels to the image the image becomes random and produces rarely excellent results. In this blog post, we’ll delve into the fundamental raster vs vector graphics, explore their advantages and disadvantages, and help you determine which format best suits your specific needs. Resolution applies to both raster and vector images, but it works differently.
As vector images are composed of mathematically-defined points, every change in color or tone would require you to create a new line, point, curve, and equation. A skilled designer using the best graphics design software can work wonders with a vector image. However, in terms of elements such as gradient, tone, color, and shadows, raster and vector graphics a vector image can never truly compare to what a raster image can offer. It is always going to fall short of the complexity and subtlety the latter provides. Vector graphics, on the other hand, are made up of plenty of paths, mathematically defined in terms of ratios, proportions, width, height, and other dimensions.
Scalability of vector and raster
They showcase finer nuances in shading and light at higher resolutions. However, raster files, especially high resolution files, are very large. Vector images are quite lighter than their raster peers because their dimensions are defined by mathematical calculations and not by millions of pixels. The high efficiency of their file sizes makes them much more convenient to transfer them from one device to another. Plus, they carry a lot of information in a relatively small file size format (compared to the same file size of a raster image format).
This is especially common with brochures, catalogs, and other print projects that combine illustrations and type with photographs. Vector images are not as accessible as rasters, but you can save your vector image as a vector PDF for sharing, as that’s a format most users can open. As a graphic designer, it’s important to know the difference between raster and vector image types. When working with digital files, these are two terms you’ll come across often. Each one has its own advantages and disadvantages, so it’s essential to have an understanding of what they are and when to use each one.
Flexibility of vector and raster
Photographs are the most common raster images, but any digital graphic can be a raster. Other common raster images include 3D graphics, abstract backgrounds, and watercolor backgrounds. Choosing the wrong format can result in a loss of quality—a degradation of individual pixels that lowers image resolution.
What this allows one to do is to zoom in an image to infinite precision. They are ideal for situations in which an image might be used at various resolutions and dimensions. If you want to create an image with intricate details mimicking natural textures like a digital painting choose Raster.
Sketchbook Pro and Corel Painter are other common raster editors, and file formats for raters include JPG, PSD, BMP, PNG, GIF, and TIF, just to site the most common examples. Rather than being comprised of square-shaped pixels, vectors are made up of mathematical curves and lines, meaning vectors display visual information differently than raster images. So, while vectors are ideal for scalable logos, typography, and design, they’re not the best choice for photographic images. In the example image above, the raster version of the photograph (on the left) looks best.
