How To Draw a Polygon
A Simple Help Page by Mary

Note: See Page Two - Compositing on a Polygon
NOTE: There have been many tutorials written on how to draw a polygon. This is merely my interpretation and written for my own benefit; if anyone else can get some good out of it, well and good. :-)
I would recommend using graph paper--there is printable graph paper on-line or buy a pad of paper. Mine has 1/4 squares and I count each square as 10. So I drew a square that was 30 squares by 30 squares--in other words, 300x300.
First, make a blank at Image Magick. Go to the first page, scroll down to the slots. Put 300x300 in the size, under Format, choose "xc", and color is "none". Scroll back up and click "view".
On the next page, scroll below the picture to the paint options. Choose "replace", "color" and
type "mistyrose" in the color slot. Scroll up to the blank and click on it to activate the yellow arrow. Click in the center of your blank. On the next page, you'll see your mistyrose blank.
Here is a picture of what I will be explaining.

There are nine sets of numbers, the last set being back at the starting point. Each set is a point on the blank. Start at the upper left hand corner.
The first set of numbers is +100+50, which means 100 pixels from the left and 50 pixels from the top.
The second set of numbers is +200+50 which means 200 pixels from the left and 50 pixels from the top. Notice they are both 50 pixels from the top.
The third set of numbers is +250+100 which means 250 pixels from the left and 100 pixels from the top. And so on around the polygon. The last set will be the same as the first set because that's the starting point. It completes the polygon.
After making your mistyrose blank, click on "draw" at the top. Choose polygon in the menu. The numbers in the text area would be +100+50 +200+50 +250+100 +250+200 +200+250 +100+250 +50+200 +50+100 +100+50. Put white in as your fill color and click "draw".
Notice that the first and last sets of numbers are the same. They are the beginning and ending point.
Each set of numbers is a point on your graph paper.
I hope this helps to clear up some of the mystery of drawing. If you have any questions, you can e-mail me at Kitkat3L(remove)@webtv.net or find me here. Feel free to share this help page with whomever or wherever you wish.
Have fun!!!
