Assignment 2
We briefly talked about circles in Assignment 1 and it was made in the center of the drawn square on your graph paper. You can use the same drawing or make another 200x200 square, which would be 20 squares by 20 squares.
Suppose you wanted a circle in another place on your square? Here's an example---
+100+100 was the exact center of the blank and also the center of the circle in Assignment 1. If you want a circle in the lower right of your blank, make a dot on your paper where you want your circle to be. Now, count over two or three squares to the left and make a dot. Do the same for the top, right side and bottom. Now, connect the dots with a curved line and see if that's what you want.
Count the squares from the left side of your drawn square to the center dot. Label the dot with the number. Count the squares from the top of the square to the center dot.
My circle was 170 (17 squares) from the left and 170 from the top.
Now, count the squares to the left side of your circle. That number will be the same as the number of squares to the top of your circle. Mine was 2 squares or 20. Therefore, my numbers would be +170+170 +20+20 +0+360. The first +20 is the number of squares to the left side of your circle. The second +20 is the number of squares to the top side of your circle.
Take your 200x200 blank to Image Magick, click on "draw" and choose "ellipse". Put your numbers in the slot, choose a fill color or a stroke color and a stroke width, if needed. Click draw.
Do the same procedure for the other three corners. If you want your design to be geometrical, your circles will all be the same distance from the sides of the blank and will all be 20 squares from the center to the sides.
The numbers for my circle in the upper left would be +30+30 +20+20 +0+360.
My circle in the upper right hand corner would be +170+30 +20+20 +0+360.
The circle in the lower right hand corner would be +170+170 +20+20 +0+360.
The circle in the lower left hand corner would be +30+170 +20+20 +0+360.
Now if I want a circle in the direct center of that drawn square. I know that the first set of numbers will be +100+100. So I counted over 3 squares on each side and drew a curved line. Therefore, my second set of numbers would be +30+30 and then of course, the +0+360.
I decided to draw criss-cross lines. I drew from the center of the circles to the opposite corner. Use line when you draw. My first line was drawn using +30+30 +170+170. The second line was drawn using +30+170 +170+30.
Remember, every point on your drawn square on the graph paper, will have a set of numbers----it will be so many squares from the left and so many squares from the top.
