What are Vector Graphics?
In the most fundamental of fashion, vector graphics are a type of digital image that uses mathematical equations to create shapes, lines, and colors. Unlike regular photos or images on your phone or computer, which are made up of tiny dots called pixels, vector graphics are created using points, lines, curves, and polygons. This makes them unique because they can be scaled up or down without losing quality. Changing the size of a vector graphic is like drawing a picture with a pencil and then erasing it to make it bigger or smaller—it still looks just as sharp and clear.
They are important because they are widely used in graphic design, advertising, and web development. Logo designs, animations for a video game, and app UI are some of the most common applications where vector graphics are the preferred industry choice. They are also lightweight in terms of file size, making them easy to share and work with.
How Vector Graphics Work
At the heart of vector graphics is mathematics. Instead of storing information about each image in pixels, vector graphics use mathematical formulas to define shapes. For example, a circle in a vector graphic is not made up of thousands of tiny colored dots but is defined by a mathematical equation that describes its center, radius, and color code. Data about mathematical functions takes less space to store than data about color information or pixels, making vector graphics suitable for a majority of web-based designs.
The key components of vector graphics are paths and anchor points. Paths are lines that connect points, and anchor points are the points that define the shape of the path which can be straight or curved. Since 2D designs are made of shapes that can be outlined using curved lines, these paths and anchor systems form the basis of all vector graphics. Colors, gradients, and patterns can then be applied to these paths, or a careful arrangement of mathematical equations, to create even the most complex of designs.
This mathematical approach makes vector graphics resolution-independent, meaning they can be scaled to any size without losing quality. They are ideal for designs that need to be used in multiple formats, such as logos, icons, and illustrations. Again, the data is stored in math, so it is easy to manipulate or scale across different printing/display mediums. In other words, it is easier to tell a printer to print along a mathematical function than a set of color boxes. Similarly, it is easier to tell a TV display to light up all the pixels that fall on a certain equation of lines, than to light up a set of specific pixels.
Another important aspect of vector graphics is the file formats they are saved in. File extensions like .SVG, .AI, .EPS, and .PDF are commonly used for vector graphics. Each of these formats has its own purpose and advantages. For example, “.svg” (Scalable Vector Graphics) is a web-friendly format supported by all web browsers. “.ai” (stands for Adobe Illustrator) is the format for saving vector files created using Illustrator and is widely used by professionals. “.eps” (Encapsulated PostScript) is a format that can be used across different software and “.pdf” (Portable Document Format) can be viewed on almost any device.
Raster Graphics vs. Vector Graphic
The term ‘raster graphics’ comes from the word ‘raster’, which has its roots in the Latin word ‘rastrum’ meaning ‘rake’. Historically, the term was used in the context of scanning and displaying images. In the early days of television and computer displays, images were created by scanning a beam of light or electrons across a screen in a series of horizontal lines, much like the teeth of a rake moving across a surface. This process of scanning lines to build an image became known as raster scanning, and the grid of lines formed by this process was called a raster.
When digital imaging technology emerged, the concept of raster scanning was applied to how images were stored and displayed on computers. In this context, a raster image is essentially a grid of tiny squares like a piece of graph paper, or pixels (short for ‘picture elements’), arranged in rows and columns. Each pixel contains color information, and when viewed together, these pixels form a complete image. The name ‘raster graphics’ stuck because it reflects the grid-like structure of these images, which is reminiscent of the raster scanning process. Examples of raster graphics include photographs and images taken with a digital camera.
However, because raster images are made up of a fixed number of pixels or have a fixed resolution, resizing them can lead to distortion or pixelation. On the other hand, vector graphics can be scaled infinitely without losing quality because they are based on mathematical equations.
So, when should you use which version? Vector graphics are perfect for designs that need to be resized frequently, such as logos, icons, and illustrations. Raster graphics, on the other hand, are better suited for detailed images like photographs where color gradients and fine details are important. Color gradients and fine details make images look realistic in the way our eyes see them –our eyes do not see in mathematical equations but in reflections, blurs, and gradients of color and light.
Each type has its pros and cons. Vector graphics are lightweight (take less storage space), scalable, and ideal for precise designs, but they may not be suitable for highly detailed or realistic images. Raster graphics, while great for detail, can become large in file size and lose quality when resized.
Applications of Vector Graphics
Vector graphics are used in a wide range of industries and applications. One of the most common uses is in graphic design. Designers use vector graphics to create logos, posters, and brochures because they can be easily resized and edited without losing quality. For example, a company logo designed as a vector graphic can be used on a business card, a website, or a giant billboard without any loss of clarity.
Another important application is in motion graphics and animation. Vector graphics are often used in cartoons and animated videos because they can be easily manipulated and scaled. In the world of fashion and textiles, vector graphics are used to create patterns and designs for clothing. They are also used in engineering and architecture to create technical drawings and blueprints. The precision and scalability of vector graphics make them indispensable in these fields.
How to Create Vector Graphics
Creating vector graphics might sound complicated, but with the right tools and a bit of practice, anyone can do it. Here’s a step-by-step guide to help you get started:
1. Choose the Right Software
The first step in creating vector graphics is selecting the right software, and this choice can significantly impact your workflow and the quality of your designs. Popular options like Adobe Illustrator, CorelDRAW, and Inkscape each offer unique features for different needs. Adobe Illustrator is the industry standard, known for its catalog of tools and integration with other Adobe products. CorelDRAW is great for beginners, while Inkscape is a free, open-source alternative perfect for those on a budget.
2. Start with Basic Shapes
Most vector graphics begin with basic shapes like circles, squares, and triangles. These simple forms serve as the foundation for more complex designs. Using the shape tools in your software, you can quickly create these elements and manipulate their size, proportions, and orientation.
3. Combine and Edit Shapes
Once you’ve created your basic shapes, the next step is to combine and edit them for more complex designs. For instance, the Pen Tool allows you to draw custom paths and curves. The Pathfinder Tool lets you merge, divide, or intersect shapes to create new forms –you can combine a circle and a rectangle to create a cloud or use the Pathfinder Tool to cut out a star from a square. This step is where you can transform simple shapes into intricate and visually appealing designs.
4. Add Colors and Gradients
Most vector graphics editors offer a wide range of tools for customizing colors, such as solid fills, and gradients that mix multiple shades. You can also apply patterns or textures to your design. For example, a gradient fill can turn a simple circle into a realistic sphere, while a pattern can make a rectangle look like a brick wall.
5. Refine Your Design
Refining your design is where you need precision and patience to add the finishing touches to your design, so it looks unique. For example, you might use a pen vector graphic tool to tweak the curve of a leaf to make it look more natural, adjust the angle of a line to create a sense of movement, or add a shadow to the sphere to give it a 3D appearance.
6. Export Your Work
Once your design is complete, you can export it in various formats, such as SVG, Ai, EPS, or PDF. These formats are widely supported and ensure that your vector graphic retains its quality.
