  Scan Conversion in Computer Graphics “When we represent regular objects in the form of discrete pixels, it is called Scan Conversion.”  Every graphics system must transform the primitives into a collection of pixels. The scan conversion is also called  “Rasterization.”  Each pixel in the graphical system has two states either  on  or  off . “The Scan Converting rate is a technique that is used in video processing. In this technique, we can change the horizontal and vertical frequency for many different purposes.”  We use a scan converter to perform scan conversions. We can define a line by its starting and ending points. On the other hand, we can define a circle by its radius, circle equation, and center point. Methods of Scan Conversion We can perform scan conversion by using two methods. Analog Method Digital Method Analog Method:  It is the best method for analog videos. A large number of delay cells perform the analog method. The Analog...
