Vector Graphics Explained

Do you need to produce illustrations on your computer for your business or organisation? Finding out how to happy Halloween use object-oriented graphics will enhance your company’s literature and the vector drawing software is not difficult to use.

Vector graphics make such a difference to any form of representation produced on a computer. This article explains what they are and the differences between vector and raster graphics. Learn how to use object-oriented graphics to enhance your organisation’s cards, flyers and letterheads.

What are vector graphics?

They are created on a computer and are a popular representation format.

In the following article, we’ll explain exactly what they are, what benefits they have over raster graphics and when they are best used.

A vector is a line

But it doesn’t have to be a straight line. Object-oriented graphics are statistical equations that consist of co-ordinates, positions and challenge information. They’re similar to a dot-to-dot drawing, albeit slightly more sophisticated.

Think about an aeroplane taking off from the ground and rising to an altitude in the sky. There is a series of factors that determine the challenge between the point at which the planes leaves the earth and the point at which it reaches cruising altitude, such as speed, angle at takeoff etc.

And it’s a similar case with object-oriented graphics. To draw a curled line, for example, the vector graphics programme requires the co-ordinates of the line’s two end points. Once these have been plotted, you can create a challenge between them. The mathematics will have been calculated in the background.

If a shape needs to be enflamed, numbers are added to the equation behind the scenes presenting the same shape at the same quality, but much bigger. Colours and styles are then added.

But object-oriented graphics don’t restrict you to simple 2nd images; incredibly detailed, almost photo-like results can be achieved.

Increase size without decreasing quality

No matter what size you widen or dissove object-oriented graphics, the quality will remain exactly the same; it will be 100% sharp and clear.

Compare this to raster graphics where the images consist entirely of squares of colour known as pixels. Resizing these graphics forces the software to estimate which pixels will fill an increased image, causing pixelation giving a blurry and unclear effect.

The ability to increase a vector’s size without sacrificing quality is also closely connected to file size. Even if your vector visual is the size of a billboard, the file size will still be relatively small, especially when compared to that of a raster image.

This is because a vector file only records the information related to the graphic’s objects, i. e. co-ordinates, positions etc., whereas raster graphics need to record every single pixel in an image, leading to a much bigger file size.

One disadvantage to vector graphics in the past was that you couldn’t achieve anywhere near the photographic, lifelike quality you could in a raster image. However, developments in software mean that this is now more feasible, although the process can be time-consuming.

Perfect for print and screen

Vector graphics are used in websites, animation and business branding materials such as logos, letterheads and flyers. A logo, for example, needs to be flexible and versatile in its design so it can be applied in varying sizes and across a range of media which could be anything from an A4 page of paper sideways of a car.

The fact that you can easily widen and dissove vector graphics to any size makes this possible. And it’s not just in printed materials where vector exceeds expectation.
The format has become popular on websites too because of a combination of small file size, high quality, and compatibility with all major internet browsers and most smartphones one the market.

Raster graphics, on the other hand, can boast high quality, but at a cost of a larger file size. The downside here is that a larger file forces page load times to increase, which might mean a potential visitor has to wait for a website to appear.

Vector graphics software makes it easy

As you can see, vector artwork is ideal for a number of situations and, with software readily available and far from expensive, there really is every reason to try your hand at it.
