Functioning of hardcopy devices and Output primitives
1. Functioning of hardcopy devices-laser printers and dot matrix printers, plotters.
2. Output primitives: Graphics programming packages provide basic geometric shapes such as line segments, circles, ellipses and other simple curves as building blocks for defining more complex structures. These are known as output primitives.
What is scaling and shearing? The scaling transformations alters the shape of an object and can be carried out by multiplying every vertex (x,y) by scaling factor Sx, Sy where
