opencv: getPixel() not reflecting drawRectangle()

Question

When I draw a red square into an image, I expect the pixels in that square to be 'red'. However, they turn out to be black...

>>> from SimpleCV import Image,Color
>>> Color.RED
(255, 0, 0)
>>> i=Image((100,100))  
>>> i.drawRectangle(10,10,20,20,Color.RED,0,255) 
>>> i.getPixel(15,15)
(0.0, 0.0, 0.0)                     

Any Ideas what I'm doing wrong?

Answer 1

.... Apparently, the drawRectangle call draws onto the current drawing layer. After a call to applyLayers(), the pixel was more as expected.

>>> from SimpleCV import Image,Color
>>> Color.RED
(255, 0, 0)
>>> i=Image((100,100))  
>>> i.drawRectangle(10,10,20,20,Color.RED,0,255) 
>>> i.getPixel(15,15)
(0.0, 0.0, 0.0)   

Here goes:

>>> i=i.applyLayers() 
>>> i.getPixel(15,15)
(254.0, 0.0, 0.0)
