Output Primitives and Geometric Transformations
You learnt how some basic geometric objects such as line segments, circles, ellipses and other curves are processed for plotting on a display unit. In most of the graphics packages you will find that polygons are also used as standard output primitives. Filled polygons with single solid color (or other alternatives for filling the interior) are provided as shape primitives.
QUESTION (a) In Automatic Contrast Adjustment briefly explain how to stretch an image to its full intensity (b) Write down a mathematical function of a Modified Automatic Con

Hue and Saturation: A light source produced by a sun or electric bulb emits all frequencies within the visible range to give white light. When this light is incident upon an objec
What is translation? Translation is the process of changing the position of an object in a straight-line path from one coordinate location to another. Each point (x, y) in the
Magnify a triangle with vertices A = (1,1), B = (3,1) and C = (2,2) to twice its size in such a way that A remains in its original position. Answer: You need to apply scaling b
