Objective
Work with loops Work with graphics
Assignment
This assignment will have you create an image that will show your initials in the display. As a demonstration, I’ve including my initials, with a variation on how I could draw the M. In order to ensure practice using loops, the only graphics command that can be used to draw in the display is point. You CANNOT use the line command, or any other command other than point. This will require a loop in conjunction with the point command to draw each line in each letter.
Specifics
Write your initials, or any other combination of 3 unique letters, to the display. Before starting each letter, write a comment stating the letter to be displayed and then give the variables startX and startY a value. The startX and startY variables will be the upper left hand corner of the letter. These variables do not have to be called startX and startY, the point is to have variables which store the starting location of that letter.
Use relative locations, using the startX and startY variables, to create your letter using the point command. ALL commands used to draw the letter MUST use startX and/or startY or distances from startX or startY, such as startX + 100 or startY + 60.
To simplify the drawing of the letters, set the width of the line from the default of 1 to something larger using setLineWidth(). I set the width in my example to 15.You can draw block letters, as I did with the leftmost M, or figure out how to include the slope to draw angled lines. Either approach is valid, you will not be graded on artistic style. However, each letter must include at least 2 lines/for loops.
I decided to make each letter 100 pixels by 100 pixels. You do not have to use these dimensions. I think it will be easier if all of your letters have the same width and the same height. I would also draw the letters by hand on a graph, noting the starting and ending points of each line, and how they relate to the starting x and y.
Challenge
If you look at the letter “O” you will find 4 lines. In the simplest solution you will have 4 for loops. However, the letter can be created with less than 4 loops, since several of the loops will have some of their coordinates in common. Nothing says that two lines (parallel lines) can’t be draw with a single loop. I was also able to use a single loop to draw the diagonal lines in the second M.
Starter code
from SimpleGraphics import * setSize (700, 300)
setBackground ("light gray")
setOutline ("dark blue")
setLineWidth (15)
setWindowTitle ("Drawing TOM")
#drawing T startX = 100 startY = 100 #I’ll give you the top line of the T for x in range (startX, startX + 100):
point (x, startY) ...
#drawing O
setOutline (“white”)
startX = 220
startY = 100
#now draw the lines for the O …
#drawing M – approach 1
setOutline ("dark red")
startX = 340
startY = 100
#now draw the lines for the first M …
#drawing M – approach 2
startX = 460
startY = 100
#now draw the lines for the second M …
