WebApr 9, 2024 · Scan conversion Explanation: The translation of a specified picture description into a series of pixel-intensity values for storage in the frame buffer is known as digitization, it is also known as Scan conversion. Question 14: A most suitable feature of a Graphics Card is to, Send graphical data to the output unit WebSCAN CONVERTING LINES, CIRCLES and ELLIPSES LINE DRAWING Description: Given the specification for a straight line, find the collection of addressable pixels which most closely approximates this line. Goals (not all of them are achievable with the discrete space of a raster device): •Straight lines should appear straight.
WebFeb 20, 2024 · We can define a straight line with the help of the following equation. y= mx + a Where, (x, y) = axis of the line. m = Slope of the line. a = Interception point Let us assume we have two points of the line ( p1, q1) and ( p2, q2 ). Now, we will put values of the two points in straight line equation, and we get y = mx + a q2 = mp2 ... (1) WebSep 1, 2024 · What is Scan Conversion?
