Explanation:
Detailed explanation-1: -On raster systems, lines are plotted with pixels, and step sizes in the horizontal and vertical directions are constrained by pixel separations. That is, we must “sample” a line at discrete positions and determine the nearest pixel to the line at each sampled position.
Detailed explanation-2: -Answer: c Explanation: Using pixels lines can be plotted.
Detailed explanation-3: -Answer: d Explanation: The DDA is a faster method for calculating pixel positions.
Detailed explanation-4: -Answer: d Explanation: Bresenham’s line algorithm is a very efficient and accurate algorithm.
