1
What is each black and white bit mapped graphic made up of?
A grid of pixels
What happens when you ‘blow up’ a bit mapped graphic?
It will look blocky/pixelated
What is an advantage of using a bit mapped graphic? What is a disadvantage?
- An advantage is that you can edit the fine detail by zooming in at pixel level
- A disadvantage is that bit-mapped graphics take up a lot of storage as it requires millions of pixels and colour codes
What are vector graphics made up of?
A number of shapes layered on top of another and these shapes are made up of a list of attributes
What happens when you ‘blow up’ a vector graphic?
The edges of each shape stay smooth and clean
What would a vector graphic be suitable to be used for?
From logos on small business cards to billboard signs as they don’t become blocky when they are scaled
What is an advantage of using a vector graphic? What is a disadvantage?
- An advantage is that the file size is small as it’s only saving the objects and their attributes
- A disadvantage is that you cant zoom into fine detail at pixel level
