photographs) are used for any image that requires editing.īecause a raster file has to store individual colour information for every single one of those millions of dots, the size of the file can be quite large. It's for this reason that raster graphics (i.e. Even if you changed the colour value of a thousand dots, the image would look largely the same. Imagine if you were to change just one of those 20 million dots, you'd hardly notice any difference. This gives editors a great amount of control over the customisation of an image. The reason for this is that every single one of those millions of dots can actually be edited one-by-one. Raster graphics also offer more control than vector graphics during the editing process. So if your image is 300 DPI, there are 300 dots in one square inch of the image. It refers to how many 'dots' of colour are present in one inch squared of an image. Similarly, if you've ever heard your graphic designer use the term DPI (Dots Per Inch), this is essentially the same concept. As you can imagine, this is going to be exceptionally high quality. So if you have a 20 megapixel camera, the image you end up with is made up of around 20 million dots. If you've ever wondered what megapixels actually means, it's roughly a million pixels (or dots).
Because most raster graphics are made up of so many dots (most modern cameras have millions of dots), you achieve a level of detail that just isn't possible with a vector graphic.
Difference of raster and vector full#
The quality and detail of many modern day raster graphics is extremely high and generally, they're more detailed than vector graphics (click the link above to see the full quality of the raster image). Photographs are by far the most common type of raster graphics used in the modern world. The more dots there are, the higher quality your image will be as the dots are smaller. When you buy a camera with X amount of megapixels, this is essentially just a reference to the amount of dots that make up the image. If you've ever taken a photograph, you'll already be familiar with a raster image. The important thing to realise is that these are essentially the same thing, so don't get confused if your graphic designer uses them interchangeably.Įach of these thousands of dots of colour combine to create a raster image. When you're viewing an image on a computer screen, these dots are referred to as pixels whereas when talking about printed media, they are often just referred to as dots. magazines, newspapers etc).Įssentially, a raster graphic is an image that is made from thousands or millions of dots of colour. Most of the images and icons we see on the web are raster graphics and so are most of the images we see in various printed media (e.g.
Trust us, they'd much prefer it that way.Ī raster graphic is the most common type of graphic we see in today's world. So next time, instead of baffling your clients with puzzling words, just show this article to them and let them read through it in their own time. In this post, we'll be explaining the differences, advantages and disadvantages of vector and raster graphics in plain English. raster argument to every single one of your clients? We think this is a poor solution and so, we've done all the hard work for you. So what's the solution? Should you just carry on explaining the lengthy vector vs. Nobody likes it when their graphic designer starts using overly-complex words because understandably, not everyone is a graphic design geek with nothing better to do than learn the intricacies between vector and raster graphics. you've been a client looking to have an image enlarged) then you might have been the one feeling bemused. If, on the other hand, you've ever been on the other side of the fence (i.e.
It involves using terms like vector and raster graphics, both of which are terms that will likely serve no purpose other than leaving a bemused look on your clients face. It's at this point that you likely embark upon a long-winded explanation as to why they simply cannot enlarge a photograph of their children (taken on a disposable camera) into a ten foot canvas. Often, clients will come to you with a photograph or perhaps a business logo and depending on the quality and/or format of the file, enlargement might not be possible (due to an extreme loss of quality). If you're a graphic designer, there's probably been countless occasions where a client has come to you asking how they can enlarge an image they have, as they want to use it somewhere else.
