Learning objective

Vector graphics: Explain how vector graphics represents images using lists of objects. The properties of each geometric object/shape in the vector graphic image are stored as a list. Give examples of typical properties of objects. Use vector graphic primitives to create a simple vector graphic. 70

Read the explanation, check the common trap, then practise with flashcards and questions.

  • This point belongs to Representing images, sound and other data, especially Vector graphics.
  • You need to be able to vector graphics: Explain how vector graphics represents images using lists of objects. The properties of each geometric object/shape in the vector graphic image are stored as a list. Give examples of typical properties of objects. Use vector graphic primitives to create a simple vector graphic. 70.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Why it matters

This objective helps connect Vector graphics to exam-style questions, flashcards, and revision notes for Representing images, sound and other data.

Quick student answer

What is the fundamental way a vector graphic represents an image?

Direct answer

As a list of objects and their properties

Key terms

  • Vector graphic: An image represented as a list of geometric objects, with the properties of each object stored in the representation.
  • Primitive: A simple geometric object or shape, such as a rectangle, circle or line, used to create a vector graphic.

Common trap

Describing pixels instead of objects: Explain that a vector graphic stores a list of geometric objects and the properties of each object.
