# This program illustrates how to draw some primitives by determining their (x,y) coordinates
# in the drawing area as well as how to set some of the physical properties (size).

# Reminder: to run this program you need Quickdraw to be in the same directory or folder
# as this program. Also double check if the suffix for Quickdraw ends with ".zip" or ".jar".

import subprocess
quickdraw = subprocess.Popen(['java', '-jar', './quickdraw.zip'], stdin = subprocess.PIPE)

# Draw a circle: center at (x,y) = (0,0), radius = 100 pixels
quickdraw.stdin.write("circle 0 0 100")
quickdraw.stdin.write("\n")

# Draw a circle: center at (x,y) = (100,200), radius = 50 pixels
quickdraw.stdin.write("circle 100 200 50")
quickdraw.stdin.write("\n")

# Draw a filled rectangle: top left corner (x,y) = (200,200) width = 50 pixels, height = 200 pixels
quickdraw.stdin.write("fillrect 200 200 50 200")
quickdraw.stdin.write("\n")
