problem 1: What do you mean by the term raster graphics? Distinguish between raster and vector graphics?
problem 2: Describe how Bresenham’s algorithm takes benefit of the connectivity of pixels in drawing straight lines on the raster output device.
problem 3: Describe mid-point line algorithm? prepare the algorithm in your own words.
problem 4: What steps are needed to plot a line whose slope is between 45º and 90º by using Bresenham’s method?
problem 5: What steps are needed to plot a dashed line by using Bresenham’s method?
problem 6: Show graphically which an ellipse has four-way symmetry by plotting four points on the ellipse:
x = a*cos(0) + h
y = b*sin(0) + k
Where a = 1 b = 1 h = 0 k = 0
θ = π/4, 3π/4, 5π/4, 7π/4
