Vector vs Raster

The main difference between raster and vector is that a raster image is made up of pixels, whereas vectors are made up of mathematical calculations, meaning that it creates geometric shapes. Thus meaning that when a raster image is zoomed in, one is able to see each individual pixel of the image. On the other hand if one where to zoom in on a vector image it would still be visible and consist of smooth lines.

The pros and cons of a vector images:

Pros

• The images can be scaled indefinitely, as the image is never going to lose its quality.
• The file size is going to be smaller as a vector files only needs 4 points to create a square.

Cons

• Detail is limited, as it is not efficient enough for complex images that need exact colours. Basic gradients are possible, but its very difficult to include the detail a raster image would have.
• Effects are limited, as vectors are created from simple points and lines.

Moreover the pros and cons of a raster image are the following:

 

Pros

• Detail is unlimited, as a raster image is able to comprehend various effects, such as blurring and drop shadows.
• Detail is also unlimited as each pixel is able to have its own gradient, meaning that it can leave open endless gradients and hues.

Cons

• once an image is zoomed in it loses all of its sharpness, as a  raster image would try to guess the missing pixels.
• it takes a lot more data, as each pixel has an individual colour. Eg. if someone where to create a square, it would need 300 individual pixels of colour
