A Raster image is not scalable as they have a fixed resolution and dimensions. The pixels get enlarged if you try to zoom the image that makes the image blurry. You can always scale down a Raster image to maintain its quality. If you look closely at a scalar image you will see many equally sized squares. Raster images are just grids of pixels, like what comes out of a digital camera or a scanner. They’re more flexible as each shape is separate and you can scale up and down as much as you like, but it’s harder to make the images look natural.

When you zoom in on an image, the pixels become more apparent while the details of the image become blurry. However, if you are or are about to become a professional illustrator or designer, you will quite often work with vector formats. It comes without further saying that you will have the appropriate software in hand. There is a significant difference in how the resolutions of vector and raster formats are defined. Vector images are infinitely scalable as the mathematical formulas change when you resize the image. They retain their clarity and sharpness even when you enlarge the image.

Pros and Cons of Vector Graphics in Digital Artwork

They excel at digital photography, image editing, and creating visually rich and textured artwork. When extending raster images, however, there is a need to take care of maintaining image quality. The reason is that they may suffer from pixelation when difference between raster and vector extended. You can choose between vector and raster graphics as per your individual needs of a design project. Vector graphics are great when accuracy and scalability are critical. Producing logos, vector icons, and pictures are common vector uses.

When you create an image with Vector programs the file types will be .ai, .svg, .eps, .pdf, and .cdr. Raster images have large file size defined by DPI or PPI with fixed height and width. To transfer Raster files, it’s a good idea to compress them first. These paths are defined in terms of proportions, ratio, height, width, and other dimensions. When you resize a Vector image the mathematical equations recalculate the curves, lines, and nodes, so the image remains sharp and clear.

Vector and raster belong in every designer’s toolbox

Raster images and vector graphics have different purposes in design, and it is essential for you to understand when and where to use them for the right purpose. Raster graphics can reveal a multitude of colors in a single image and allow for more precise color editing. They showcase finer nuances in shading and light at higher resolutions. However, raster files, especially high resolution files, are very large. 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. 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.

It is because their mathematical nature allows for limitless scaling without loss of quality. Vector graphics are also ideal for text-heavy designs and infographics, where clarity and precise lines are vital. Vector images are scalable, so one version of a design will always work for every iteration of a project. However, vector images cannot display photographs in a natural looking way, and vector formats are not as well supported online as are raster formats. Adobe Illustrator and CorelDraw are the most popular vector graphics editors. In raster images zooming in can cause some tiny squares (lose quality) to appear.

Pros and cons of rasters and vectors

High-resolution vector images can be scaled infinitely without losing quality. They don’t just carry pixels but also all the information regarding the assortment of the pixels. Rasters, on the other hand, are made up of pixels or tiny dots that compose an image using color and tone. Since their building blocks are pixels, raster images do not feature the kind of scalability that vector images do. Being significantly different in nature, the two kinds of graphics have different uses, strengths, and weaknesses.

• In raster images zooming in can cause some tiny squares (lose quality) to appear.
• Raster graphics are best used when it’s important to show the smooth transition of shades and colors—for example, in photos.
• Vectors are also ideal for when you want to store a large number of files without compromising on your storage space.
• For scalable designs with fewer colors, vector graphics are ideal, despite their inability to render totally smooth color transitions.
• These designs capture the vibrant, subtle nuances of our environment.

Adobe Illustrator (and most vector programs) does provide automated tools for image tracing, though the results can be somewhat random. A vector image is an infinitely scalable digital graphic made out of mathematically calculated paths. Vectors are essentially geometric shapes that can be stretched or curved as need be. Adobe Photoshop is one of the most popular raster-based editors available and has been used to edit photographs, create graphic designs, and illustrate.

Raster vs. Vector: A Comprehensive Guide for Designers

For example, if the PDF was created in Photoshop, it will be saved as a raster file. And sometimes, a PDF can contain raster images, like JPEGs and PNGs as well as vector images. 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.

A single dot symbolizes a color, but the colorful dots together form a vibrant and complex artwork. This raster graphics approach produces images with a lot of detail. Raster graphics are excellent for picture editing and digital painting. The most common raster graphics formats are .JPG, .GIF, .BMP, and.PNG.

What is a raster image?

Resolution limits the size the image can be scaled up without being able to see pixels. On the other hand, vector images are made of equations translated into code and so they take up far less space. Since businesses need to store a large number of files on their devices, saving on space is just one more reason to opt for vector images over rasters. As a graphic designer, it’s important to know the difference between raster and vector image types.

Zoom in on a raster picture to view the information it contains – data on the color of each pixel. Zoom out, and the pixels appear to combine flawlessly to form a picture. On the other hand, allows you to view the smooth forms and curves of the image’s parts rather than individual pixels.

Finally, remember that you can always turn a vector graphic into a raster file with ease. Overall, it is important to ask yourself at the start of the designing process what it is that you are designing, and what style you are aiming to achieve. Whether it is a poster, book cover or logo design, once you have a clear vision it will be easy to decide to choose between a raster and a vector image. Using vectors in a raster-intended design is permissible because the whole image can easily be exported as a raster file. One advantage of doing so might be to incorporate different art styles within a single image for contrast. Technically, it is possible to mix vector and raster data in the same image.
