When viewed from a distance, these pixels mix or blend together to form a clear image. They’re like a mosaic made up of tiny pixels and each pixel is a tiny square with a specific color. Raster images, also known as bitmap images, are made up of a bunch of tiny pixels. When viewed at 100%, each dot corresponds to an individual pixel. An image made up of a collection of pixels is known as a bitmap.īitmap – a bitmap is a digital image composed of a matrix of dots or pixels. Most photos we see on a computer screen are raster images as they are made up of hundreds of pixels. Pixel – in computer graphics, a pixel is a dot or the smallest addressable element of an image represented on a screen. Two basic terms to take note of as we go along: What are Raster and Vector Images?īefore we actually delve into the differences between raster and vector graphics, let’s first understand what they are individually. Read on so you’ll always choose the right format for your digital printing job. In this article, we will banish all the confusion and explain the major raster and vector differences in a way that’s easy to understand. Both types also have their own applications, as well as their advantages and disadvantages. After all, both electronic files are made up in different ways to represent images.

Having known the difference between vector and raster graphics, you will now have an idea as to the software you'll use for your projects such as a business card or postcard. While all printed images and photos were taken with digital cameras are in raster format. Keep in mind that vector graphics can be only created with specialized software such as Adobe Illustrator making it impossible for photos to be taken in vector format. In short, the main difference between vector and raster graphics is that while raster graphics are composed of pixels, vector graphics are composed of paths. As a result, converted images are prone to losing quality. Take note, the size of the vector image to be converted always remains the same.Ĭonverting from raster to vector format is another story and is not an ideal choice since the image size reduces drastically, exact conversion is quite impossible. So for one to print a vector image it has to be converted from vector to raster. There are called raster devices such as printers and display devices. Vector images are identified with the following file extensions. Commands are being used to describe a series of points to be connected rather than having a bit in the file for each of line drawing. The file, in vector graphics, is created and saved as a sequence of vector statements. For this reason, vector image does not blur or becomes pixelated even when enlarged. Vector image or graphics make use of sequential commands, or mathematical formula, or programs, or line art which places lines or shapes in a 2-D or 3-D environment thus making them ideal for printing due to its series of mathematical curves. Raster images are identified with these file extensions. It is easy to scale down these images but enlarging it would mean enlarging a bitmap which makes it pixelated or blurred. Jpeg and gif are common compressed image formats so as referred to as in raster format. ![]() Algorithms are used to compress images, to help reduce file sizes. So it is simply identified that an image is a collection of pixels referred to as a bitmap. Another example of a raster image is that selfie we took with our mobile phones. Every individual pixel is simply the tiniest known element of a picture represented on a screen so therefore, the majority of pictures that we see on our computer screen are raster images. Pixel or dots is defined as a physical point in a picture. Accordingly, a bitmap is 1 bit per pixel. Larger files, therefore, need large bitmaps and more disk space. Raster graphics or images use bitmaps to store details. ![]() Behind these photographs and documents that we capture and printout are what we call vector and raster graphics. How we can capture images using our gadgets and how it is reproduced. It is quite amazing how a technology works.
