Code Snippet

import e32
import time
import appuifw
import graphics
import math
can=appuifw.Canvas()
appuifw.app.body=can
img=graphics.Image.new(can.size)
img.clear(0xffffff)     
running=1
def quit():
    global running
    running=0
appuifw.app.exit_key_handler=quit
while running:
 
	for i in range(180):
    		k=1.417*i
    		j=(0,k,k)
    		i=(i*math.pi)/90        
    		img.pieslice((50,50,100,100),0.0,math.pi/180+i,outline=None,fill=j)
 
    		img.pieslice((60,60,90,90),0.0,math.pi/180+i,outline=None,fill=0xffffff)
 
    		can.blit(img)
    		e32.ao_sleep(0.001)
 
	for i in range(180):
    		k=1.417*i
    		j=(0,255-k,255-k)
    		i=(i*math.pi)/90        
    		#can.clear(0xffffff)
    		img.pieslice((50,50,100,100),0.0,math.pi/180+i,outline=None,fill=j)
 
    		img.pieslice((60,60,90,90),0.0,math.pi/180+i,outline=None,fill=0xffffff)
    		can.blit(img)
