- Vector graphics are created from mathematical formulas used to define lines, shapes and curves.
- Edited in draw programs.
- Shapes can be edited by moving points called nodes(drawing points).
- Computer displays are made up of grids of small rectangular cells called pixels.
- A vector graphics program uses these mathematical formulae to construct the screen image.
- The mathematical formulae determine where the dots that makeup the image should be placed for the best results when displaying the image.
- Resolution Independent
- Small File Sizes
- One example of vector graphics format is SVG(Scalable Vector Graphics).
Simplest geometric objects
1. Lines and polylines.
3. Circles and ellipses.
4. Bezier curves and bezigons.
Advantages of Vectors
-
→Regardless of how much the image is enlarged or reduced, the image definition and quality remain the same.
-
→Easily transferred over the Internet.
