Lesson 16- Vector Images
Download as PPTX, PDF0 likes101 views
Vector images are made of geometrical objects and shapes defined by mathematical formulas, rather than a bitmap grid of pixels. This allows vector images to be scaled to any size without loss of quality or pixilation. Examples shown include circles drawn with SVG/HTML5, demonstrating how vectors store geometric data rather than a pixel representation. Vector images are best for graphs, diagrams, and illustrations rather than photographs.

- 2. Learning Outcomes By the end of this lesson, you should be able to : (a) Differentiate between a vector and bitmap image?
- 3. What is a vector image? • A vector image is made of geometrical objects/shapes. • The computer stores mathematical formulas that tell it how to draw the shapes and lines. • It is best used for graphs and diagrams. • Vector graphics are not a good way to store photographs. • The file extension for vector image is .svg. • No pixilation effect occurs with vector images.
