A Help Page by Mary
After studying several different tutorials relating to the drawing of circles, this is only my interpretation. Thanks to all the writers for their good instructions. If there are similar phrases or words from other Circle tutorials in this Help Page, it is purely coincidental.
I have made an illustration using a 200x200 blank.
Using "Circle" in the drop-down menu at Draw, there will be two sets of numbers for drawing a circle. The first set is the center of your circle. In the illustration, it is in the exact center or +100+100.
The second set of numbers is figured from any point on the circle; however, for this exercise, we will use the center of the left side. Use point and click to find the two numbers for the center of the left side.
In her tutorial, Susanna Mitchell says "you should always keep the vertical numbers (second numbers of both sets) the same." Therefore, your numbers for this circle would be +100+100 +50+100.
(Note: This rule only applies when you use the center of the left side of your circle to obtain your numbers.
Here's an image of a lighthouse that I have used point and click to find the center. (eyeballing)
For printers' convenience, the url is http://www.wtv-zone.com/Kitkat3l/Help_Pages_2/lighthouse_2_keep.jpg.
I then went to the side where I thought the edge of the circle would be. I pointed and clicked and got the numbers +32+166. The center is +144+162; therefore, I changed my second set of numbers to +32+162 as per Susanna's tutorial. So my two sets of numbers are +144+162 +32+162. I always do a test draw in case I need to adjust the circle.
Here's my version of cutting the circle out.
Back up and click Input and make a white blank the same size as the image (400x300). Go to draw, choose circle, use the same numbers, and a fillcolor of mistyrose. Matte out your white around the mistyrose circle. Composite your picture using "In".
If you'd like an edge on your picture, click on Draw, choose Circle, use the same numbers and a color of your choice and a width of 4 or 5.
Trim your picture and upload.
My finished circle--
Something to try---With a 200x200 blank, try these numbers--
Use +200+200 as the first set of numbers. Then try each of these as your second set of numbers.
+120+140
+260+120
+280+260
+120+260
You'll find that they all make the same circle.
